Forged Automotive Racing Pistons 

Wiseco’s new ArmorGlide TM skirt 

coating is the result of extensive testing, 

development, and benchmarking 

through our in-house dyno program. 

6 

The outcome: 

Minimized friction 

Maximum horsepower 

Improved wear resistance 

In addition, ArmorGlide allows the 

piston to be fitted tighter within the 

bore than a non-coated piston. This 

produces better ring seal, reducing 

noise due to piston rock. 

Skirt Coating

Designed to accommodate the reluctor ring on 

stroker cranks without having to notch the pin bosses. 

Offset pins like O.E. and skirt shapes specifically 

designed for street applications make these the best 

pistons available.

excellent wear properties. 

• Anti-detonation Grooves help keep the top ring 

groove free of carbon.

parts are the best available. 

Contoured domes and other 

special features, along with a 

dedicated forging, ensure more 

than adequate thickness for the 

highest horsepower.

proprietary ArmorGlide material. 

Benefits include - longer engine 

life, increased HP, noise reduction, 

and much tighter dimensional 

tolerances than typical spray-on 

coatings. Controlled curing 

processes guarantee the best 

possible results.

Wiseco Quick 16 pistons are designed to fit conventional heads from today's leading manufacturers. 

Wiseco Quick 8 pistons are designed to allow for additional flycutting as necessary. Domes that can be cut to a 

lower rise to tune volume for different combustion chamber volumes. Every 2.76 grams off dome/valve pockets = 1cc 

volume. 

• New skirt coatings use Wiseco’s proprietary ArmorGlide material (Superior to graphite or Teflon based formulas). 

Benefits include - longer engine life, increased horsepower, noise reduction, and much tighter dimensional 

tolerances than typical spray-on coatings. Controlled curing processes guarantee the best possible results. 

• Designed with input from today's leading edge engine builders and Pro Stock technology to fill the demands of 

today's big valve, big cubic inch Sportsman Series engines. 

• Vertical Gas Ports located away from valve pockets. 

• Oil reservoir below oil drainbacks allow the lower rail to act more efficiently for optimal oil control. 

• In stock availability of kits and singles keeps you racing all season.

World renowned for our work building race winning pistons, Wiseco 

utilizes experience from a diverse background of the most sophisticated 

engines. 

Wiseco's Pro Tru line creates the best value in forged pistons today. 

These American made pistons are forged and machined by skilled Ohio 

craftsmen with state-of-the-art forging presses and CNC machines. 

By using dedicated forgings specific to the final piston shape, Pro Tru 

pistons are stronger and lighter than industry standards. 

Pro Tru pistons also come in a variety of volumes that allow the engine 

builder to choose the exact compression ratio required for their engine. 

1 Dome and reverse dome shapes have smooth contoured surfaces for better combustion 

and optimal quench for detonation reduction! 

2 Symmetrical valve pocket designs allow maximum flow around the valves during overlap 

and accommodate oversize valves and high lift cams. 

3 New screen printed skirt coatings for 2010 use Wiseco’s proprietary ArmorGlide 

material. Superior to graphite or Teflon based formulas, benefits include longer piston 

life, increased horsepower, noise reduction, and much tighter dimensional tolerances 

than typical spray-on coatings. Controlled curing processes guarantee the best possible 

results. 

4 Complex Piston skirt profiles reduce power robbing friction and rock, which promotes 

stability in bore for optimum ring seal. 

5 Precision machined ring grooves provide excellent surface finish and flatness for 

maximum ring seal and minimized blow-by and oil consumption. 

6 World class, ISO Certified, forging facility that utilizes the latest technologies, featuring 

complex forged shapes, advanced materials, and feature- aligned grain flow technology.

With the leading tip of the lock in 

the 12 o'clock position, insert your thumb thru the 

center of the lock and hook it under your thumbnail 

at the 10 o'clock position (roughly 1/2" to the left 

of the leading tip). Install the leading tip into the 11 

o'clock position of the groove. (If the wrist pin hole 

intersects the oil ring groove, lock installation is 

slightly more difficult as the lock will catch on the 

bottom ring land). 

The leading edge of the lock should catch in the 

groove, allowing it to stay on its own. Continue by 

applying pressure with a counter-clockwise motion 

until it fully snaps into place. 

The correct number of Spiro Locks MUST 

be installed in each piston or severe engine 

damage may occur. Do not over-stretch or reuse 

Spiro Locks. Do not install Spiro Locks in 

press-fit pin applications.

The Multi-Valve Piston Technology Leader 

Wiseco is world renowned for their work building 

race winning pistons for compact engines 

featuring small bores, multi-valves, and high 

RPM applications for many years. Wiseco utilizes 

experience acquired from a diverse background 

of the most sophisticated engines in such venues 

as Formula 1, Indy Racing League (IRL), NHRA 

Pro Stock Bike, AMA Superbike, and AMA Motocross 

to design and manufacture the highest 

technology Sport Compact piston available. 

• Generous Valve Pocket designs that allow maximum flow around valve. Note: Piston to 

valve clearance must be checked. 

• Piston Crown shapes designed to promote maximum Intake Charge efficiency thru 

scavenging mixture “Cross Flow” during intake and exhaust valve overlap. More fuel and 

air equals more horsepower! 

• Pistons designed to optimize squish or quench during compression combustion cycle 

event, resulting in resistance to detonation and pre-ignition. The end product is longer 

engine life and increased horsepower potential. 

• Complex Piston skirt profiles that reduce power robbing friction, yet promote stability in 

bore for optimum ring seal. Wiseco has added skirt coatings to the long list of standard 

features on our stocked Sport Compact pistons! 

• Precision machined ring grooves with proper orifice/accumulator volume using calculated 

groove root diameters and axial widths, featuring excellent surface finish and flatness 

providing maximum ring seal and minimizes blow-by and oil consumption. 

• World class forging facility that utilizes the latest technologies featuring complex forged 

shapes, advanced materials, and featured-aligned grain flow technology. 

• Piston weights listed may vary. 

• All specs based on U.S. engine codes unless noted. 

• All Sport Compact pistons sold complete with rings, pins & clips.

• Pistons listed with a compression ratio range: low number is with un-cut deck, high number is block decked to .030" piston to cylinder head clearance. 

• Always check piston to valve clearance - If using VTEC or like mechanisms-check w/ longer duration higher lift lobe. 

• Always run at least .030" piston to head clearance including gasket thickness. 

• If piston appears to be different than expected, please do not hesitate to call Wiseco at 800-321-1364 to verify compatibility. 

1. Most Wiseco Pistons have a offset pins. Pins must be offset same as OEM for quitest operation. 

2. Due to compression height that may protrude above the deck, it is recommended that a 1.00mm thick head gasket is used. 

3. Uses an extra thick (.200") wall piston pin. Optional .225" wall, tool steel pin also available.

MLS Head Gaskets 

These gaskets use a high pressure steel laminate design. They withstand 

extremely high shear forces that occur between an aluminum head and iron block. 

It's internal embossments expand with heat to create a better seal when under 

extremely high combustion pressures and temperatures - as is the case with heavy 

nitrous and turbo-charged applications.

These Brush hones have been specifically designed to 

clean the surface of the cylinder bore and provide a fresh 

cross-hatched surface without removing material (which 

can increase piston to wall clearance and ring end gap). 

Always use an ample amount of honing oil to carry away 

debris. Wash cylinders thoroughly, with hot soapy water, 

until paper towels remain clean with no signs of discoloration. 

Then prep cylinders with any anti-rust agent.

Tapered Ring Compressor Sleeves 

• Machined from Wiseco sleeve forgings for the same Wiseco forged piston toughness. 

• Hard anodized and Teflon coated for low friction and long wear resistance. 

• Sleeves have a smooth radius that tapers down to the specific bore size. 

• Compresses the piston rings smoothly and evenly. 

• Greatly reduces the difficulty with installing thin high-performance oil rings.

Crankshafts & Connecting Rods 

The relationship between K1 and Wiseco is an 

industry first. For the first time, rotating assembly 

components are being designed around each other 

from their inception. This enhances strength and 

eliminates mass. 

The professional engine builder will note that the 

assembly balances well and fitment is exceptional. 

Power and longevity are increased through a reduction 

in mass, friction, and windage. 

K1 Technologies 

is dedicated to providing 

world-class 

energy-transfer technology 

at an affordable price. 

Our vast experience designing, engineering and 

manufacturing connecting rods and crankshafts 

assures that we will continue providing the same top 

of the line product and customer service we have 

always provided. 

Our mission is to bring, to the racing market, high 

quality parts at an affordable price and to provide our 

customers with world-class customer service. 

We welcome your phone calls, comments, 

requests and certainly welcome the 

opportunity to be your company of choice 

when it comes to connecting rods and 

crankshafts.

Crankshafts 

• True 4340 forging. 

• Core hardened, tempered to reduce stress and 

optimize tensile strength. Nitriding process for 

hardening rather than induction heat treated 

(which leaves the area between the journals 

soft and subject to post-running deformation 

from internal stresses being relieved). 

• Magnetic particle inspection. 

• Straight oiling to journals insures constant flow 

rather than stalling at intersection as seen with 

cross drilled cranks. 

• Wide pin-end widths designed to support the 

wrist pin (which reduces pin flex and associated 

problems). 

• Excellent Journal dimensional tolerance 

(roundness, taper, bell mouth & barrel) .0002 

maximum. 

• Counterweights placed for optimal load reduction 

and ease of balancing. 

• Exception Journal finish. 

• Stress relieved. 

• Internally balanced. 

Connecting Rods 

• 4340 steel forgings. 

• Special bushing material for optimum friction reduction. 

• Proprietary bolts produced by ARP to K1 specification with 

asymmetrical threads to equally load each thread when 

under tension. 

• Pin oiling. 

• Heavy radii. 

• Thicker blades. 

• Double bridged caps reduce housing bore distortion. 

• No ridge between the blades to act as a stress riser. 

• Rod offset is designed to center small end to bore center. 

• Big end housing bore is held to +/ .000050” (50 millionths). 

• Center to center less than .001”.

You've spent a lot of time and money building an engine... 

don't risk damage by failing to take a few minutes to put it together correctly. 

It's important to note that a fastener is like a very stiff spring and it must be stretched a 

specific amount. The material’s ability to “rebound” like a spring is what provides the 

clamping force to keep the rod bolted together. If you do not stretch the bolt enough 

there may not be enough clamp load to keep the rod cap in place, which could result 

in broken bolts or spun bearings. If you stretch the bolt too much, you can exceed 

the yield strength of the fastener which will weaken it and cause it to fail. Either of 

these two conditions can result in catastrophic damage to your engine. Always 

follow the manufacturer’s instructions to prevent damage to your engine. 

Methods used for tightening Rod Bolts 

Stretch Method: Measuring bolt stretch is the most accurate method for tightening 

rod bolts and insures the correct pre-load. Simply measure the free length of the 

bolt before tightening, lube the bolt threads and rod spotface. Install the bolt into the 

rod and tighten until the bolt is stretched the proper amount. K1 Technologies offers 

an economical bolt stretch gauge for this purpose. 

Torque & Angle Method: Do not confuse this with the “Torque to Yield” method. Torque 

to Yield stretches the bolt to a point where it will no longer return to the original length when 

loosened and requires the bolt to be replaced after each use. When using the Torque & Angle method, you 

lube the bolt threads and rod spotface, tighten the bolt to a low torque value (as prescribed on the instruction 

sheet) then, using an angle gauge, turn the bolt a prescribed number of degrees to properly stretch the 

bolt. This method uses the highly accurate pitch of the bolt thread to control the amount of stretch. 

Torque Method: Torque does not measure clamp load and only measures the amount of friction that must 

be overcome to turn the bolt. The friction of the mating surfaces of the threads, rod spotface and bolt flange 

change with each tightening. When you consider the fact that different amounts and types of lubes also 

change the friction, using the torque method is like trying to hit a moving target that you cannot see. K1 

Technologies does not recommend the use of or provide torque values for tightening bolts. 

Not only do connecting rod bolts see the same tension 

loads that try to pull a connecting rod apart, the total weight 

of the tower portion of the rod is trying to follow the piston 

up through the cylinder head. Connecting rod bolts are the 

most highly stressed fastener in the engine! They need to be 

properly tightened. 

Setting a torque wrench at a given number and tightening 

until this set amount of torque is reached is easy, but it can 

be highly inaccurate. A torque wrench only measures the 

amount of resistance it takes to turn the bolts. The amount 

and type of lube that is used will affect the actual clamp load 

provided by the bolts. Also, each time a bolt is tightened, the 

mating surfaces of the threads, the spotface on the rod and 

flange of the bolt get smoother, which changes the amount of 

torque that is required to properly tighten the fastener. 

A bolt is simply a very stiff spring and it must be stretched 

a predetermined amount to keep the rod cap on and the 

bearing from spinning.

Boring & Honing Instructions 

Adherence to proper boring and honing procedure is essential to overall 

ring performance. To ensure that the bore finish will retain an oil film, it is 

vital that the guidelines listed below are followed for cast iron bores. 

• Install and torque main bearing caps 

• Use torque plates. This simulates the distortion that occurs when the 

cylinder head is mounted to the block. (hint: After boring and honing, leave 

the torque plates in place and fit/gap the piston rings to their respective 

cylinders.) 

• Allow for a minimum of .003" excess material for use as honing stock. 

• Intermediate hone to within .0005" of finished size with #220-#280 grit 

stones. (With diamond stones use #280-#400 grit.) 

• Finish hone with #400 grit stone or higher. (Use #600 grit diamond stone. 

If using hand operated equipment, set drill speed between 200-450 rpm.) 

• Finish with an appropriate stone or tool to achieve desired plateau finish 

(see below). 

Why a Plateau Finish? 

Plateau honing is the popular name for the process that replicates the 

cylinder bore surface finish normally produced by the rings after they have 

worn down the surface peaks during "break in". This technique produces 

flat areas or plateaus (Rk) on the cylinder wall after finish honing by using 

a very fine grit stone or a PHT type brush tool to remove the peaks (Rpk) 

from the surface. This lowers the overall roughness average (Ra) while 

maintaining valley depth (Rvk) in the cross-hatch pattern of the cylinder 

wall. A high Rvk value is very desirable for oil retention qualities and will 

substantially reduce "break in" time and increase ring life. 

Ra (Roughness Average) = Used to describe surface roughness as an 

average between the peaks and valleys that exist in a finish over a specified 

area, usually micro inches. 

Rpk (Peaks) = Average peak height. 

Rvk (Valleys) = Average valley depth. 

Cross Hatch = The pattern of intersecting parallel lines left after finish 

honing operations are completed. The smaller the intersecting angle, the 

larger the area (Rk) between the hone marks. 

Cross Hatch Pattern 

Maintaining the proper cross hatch angle is important for two reasons; 1. Oil 

retention on the cylinder wall and 2. The rate of ring rotation. Excessively 

shallow cross hatch angles can hinder or slow down the necessary ring 

rotation that allows dissipation of heat. It can also leave too much oil on the 

cylinder wall allowing the rings to skate over the surface leading to excess oil 

consumption. Too steep of a cross hatch angle may not provide adequate 

oil retention and can result in dry starts and premature ring wear. A steep 

pattern angle can also create excessive ring rotation that will accelerate 

ring and piston ring groove wear.

Ring Terminology 

Axial Clearance: The distance between the ring axial height and the piston 

ring groove width. 

Axial Height: The width (thickness) of the ring in the axial direction. 

Back Clearance: Distance between the inside diameter of the ring and 

the back of the ring groove when the ring is flush with the ring land. 

D-wall: A specification established by the Society of 

Automotive Engineers (S.A.E.) that dictates the radial 

width of a standard automotive piston ring by the use of 

the following formula: Bore diameter divided by 

22 = radial thickness (3.386” divided by 22 = .154”) 

➞ 

.154"➞ 

End Gap: The end gap clearance when the ring is compressed to the 

bore diameter. 

Gas Nitrided: A process used to harden the perimeter of a ring where 

nitrogen atoms penetrate the base material and form an extremely hard 

outer layer that provides excellent wear and scuff resistance. 

Ring Gaps 

As a piston moves down on the power stroke, combustion pressure 

accumulates in the land area of the piston (between the top ring and 

the 2nd ring.) This accumulation of pressure can cause the top ring to 

unseat from its sealing area at the bottom of the ring groove. 

This is addressed by increasing the gap area of the 2nd ring. This 

affords a controlled release of the inter-land pressure, and keeps the 

top ring seated on its lower sealing surface for improved performance. 

Ring Gap Table Instructions 

1) Cylinder bore size must be in inches. If measuring millimeters, divide 

bore by 25.4. 

2) Multiply your bore size by the “x Bore” column for your application. 

Proper Ring Gap Measuring Procedure 

Good 

1) Torque Plate should be attached to engine 

block or cylinder and torqued to specifications. 

2) Cylinder bore should be free of taper. 

Bad 

3) Piston ring should be square in the bore 1” 

down from the deck. 

Proper Ring Gap Filing 

1) Ring gap should be filed using proper 

ring gap filing tool. 

2) Ring gap should only be filed in an 

inward direction and square to the 

sides. 

Oil Rails & Rail Supports 

Correctly butted tips 

Use caution when grinding 

ring end gaps - A stone or 

cutter which is too coarse can 

remove material too quickly. 

Wiseco oil rail supports feature a special dimple to prevent rotation of 

the oil rail. This dimple should be positioned directly in line with the piston 

pin. Keep the rail support gap 90 degrees from the pin bore opening.

A. Neutral Barrel: A term used to describe a piston ring that 

has no torsional bias or twist. 

B. Positive Twist: An asymmetric change in the ring cross 

section that causes it to twist in an upward direction 

(toward the piston crown) aiding ring sealing of the top and 

bottom of the ring groove. Positive twist is used only on 

top compression rings. 

C. Reverse Twist: An asymmetric change in the ring cross 

section causing the ring to twist downward (toward the 

piston skirt) that enhances the second compression ring’s 

oil scrapping properties. 

Radial Width: The width of the ring in the radial direction. 

Ring Axial Sides: The top and bottom surfaces of the ring. 

Ring Face: The section that contacts the cylinder wall. 

Torsional Twist: The installed position of the ring due to a 

chamfered area on either ring side that helps the ring cross-seal.

NOTE: The chart above is a general end gaps guideline. Each ring should 

be fitted to the particular cylinder in which they are to be installed. The 

gap on the 2nd ring should always be larger than the top ring end gap, 

this will help 

reduce top ring 

flutter.

“ WhY DO I NEED TO CALIbRATE ThE O2 SENSOR WITh 

INNOvATE PRODUCTS?” ThE ANSWER IS SIMPLE… ACCURACY! 

Innovate Motorsports is the only wideband O2 device manufacturer on the market that allows the user to field calibrate the O2 sensor. 

Our patented sensor calibration allows compensation for the two main causes of inaccurate air/fuel ratio data; sensor wear and altitude. 

The alternative to calibrating your sensor in the field is to rely on the sensor’s Bosch factory calibration. The Bosch factory sensor 

calibration is done using a fixed atmospheric pressure value that may be incorrect for your location from the start! 

SENSOR WEAR 

Most popular wideband systems, including Innovate, utilize the Bosch LSU 4.2 wideband O2 sensor. This sensor has an integrated 

calibration resistor located in the connector on the plug end. Like all sensors in a vehicle, O2 sensors wear over time and being 

able to recalibrate the sensor is the only way to ensure continued accuracy. Innovate Motorsports is the ONLY wideband controller 

manufacturer that makes it possible for the sensor to be recalibrated because we do not rely on or utilize the Bosch calibration resistor. 

Without the ability to calibrate, your wideband will continue to rely on the Bosch factory pre-calibrated resistor settings as your sensor 

wears. The results of doing so have been published by Bosch in a technical document referenced below: 

LSU test bench at constant 20 degC gas temp and constant 14.7 PSI ambient. 

New After 500hr test bench run After 2000hr test bench run 

Calibrated measurement gas for 24.99 AFR 24.99 ± .73 AFR 24.99 ± 1.47 AFR 24.99 ± 2.20 AFR 

Calibrated measurement gas for 11.76 AFR 11.76 ± .15 AFR 11.76 ± .29 AFR 11.76 ± .59 AFR 

According to the Bosch spec the sensor leaves the factory with a ± margin of error of .15 AFR. In IDeAL lab conditions sensor wear will cause 

the sensor to drift to an accuracy of ± .29 AFR after approximately 500 hours and ± .59 AFR after approximately 2000 hours. In aftermarket 

performance applications where engines typically see richer conditions with higher exhaust gas temperatures, the sensor will degrade at 

a greatly accelerated rate compared to the Bosch spec. Other factors such as detergents, additives in the fuel, sensor placement and lead 

will also accelerate sensor wear even further. The Innovate Motorsports patented digital wideband sensor controller technology eliminates 

any and all inaccuracies caused by sensor wear. The simple and quick free air calibration process will ensure that you have measurements 

accurate to ± .1 AFR for the life of the sensor. 

ALTITUDE COMPENSATION 

Changes in altitude will also affect the accuracy of the 

measurements. It is important to note the Bosch spec 

tests the accuracy of the sensor at 14.7 PSI atmospheric 

pressure (sea level). In the same way that the precalibrated 

resistor can not compensate for sensor 

wear, it can not compensate for changes in altitude. 

To illustrate how important a difference in altitude 

we can look at the difference between Innovate 

Motorsports’ office in Huntington Beach, CA which is 

at sea level, and Willow Springs Raceway in Rosamond, 

Source: Bosch Y 258 K01 005-000e technical document. 

Innovate Motorsports’ recommended calibration schedule: 

Normally aspirated 

daily driver 

Turbo car, daily 

driver (tuned rich) 

Race car (running 

leaded race fuel) 

Dyno use 

Calibrate before installation of the new sensor. Calibrate the 

sensor again after 3 months of use. Thereafter calibrate once 

a year or every 20,000 miles, whichever comes first. 

Calibrate before installation of the new sensor. Calibrate the 

sensor again after 3 months of use. Thereafter calibrate twice 

a year or every 10,000 miles, whichever comes first. 

Calibrate before the new sensor. Calibrate once per race 

weekend. 

Calibrate the new sensor. Calibrate every 2-3 days, or more 

frequently, depending on usage. 

CA. The difference in altitude is approximately 2400 ft. between the two locations; this will make a difference in your measurements 

by as much as .2 AFR. If you do not have the ability to calibrate your sensor, and you happen to live in Denver (5280 ft. above sea level), 

your readings will be incorrect right from the start and will progressively get worse as the sensor degrades. 

CONCLUSION 

The purpose of installing a wideband O2 system in a high performance engine is to accurately monitor the engine’s operating air/fuel 

ratio to ensure maximum performance and safety. If you are using a wideband system that does not allow the sensor to be recalibrated, 

you are putting your engine at risk. Whether you only perform the simple calibration once when you first install a sensor, or at the 

recommended intervals; Innovate Motorsports’ patented digital wideband O2 sensor controller technology will ensure that you have 

the fastest and most accurate wideband instrument available at any price. 

The difference between a wideband that does not require calibration and an Innovate Motorsports wideband is ACCURACY.
