“RBT” <strong>Steel</strong> <strong>Billet</strong> <strong>Connecting</strong> <strong>Rods</strong>Aircraft quality, 12-point capscrew fastening system providesadded security at high rpm.Crower’s all new Radial Beam Technology design ( “RBT” ) is theultimate connecting rod, often copied by competitors, but neverreplicated to Crower's engineered standards. The radial shapebeam delivers unsurpassed beam support while reducing overallweight for greater throttle response...quicker deceleration intothe corner and faster acceleration off the corner.Drilled and chamfered pin oilhole on all Crowerods providesadditional oil at the pin end toprevent galling. The high alloy,aluminum-bronze, one piecebushing delivers long, reliableservice.H11 - Tool <strong>Steel</strong> bolts rated to220,000 p.s.i. come standard.For extreme duty, Crower highlyrecommends the AMS5844 rodbolt upgrade rated to 280,000 p.s.i.for ultimate clamping ability.Extra strength at the critical web areareduces the big end pinch foundin other inferior designs. Big endroundness is paramount for longbearing and connecting service.Pin boss dynamics are essentialwhen designing a highperformance connecting rod. Tomaintain trouble free operation,Crower beefs up the pin eye area.The Crower Maxi-Light is aproven performer on the racetrack. Tapered beam designdelivers the strength you need ina lightweight, yet reliable profile.Hollow dowel alignmentfastening system providespositive cap alignment andprevents unwanted cap walk.RADIAL BEAM TECHNOLOGY (“RBT”)MAXI-LIGHT DESIGNCrower’s exclusive “RBT” Maxi-Light design is arevolutionary new beam shape that removes excessmaterial from noncritical stress areas for the lightest,yet strongest connecting rod available on the market.Choose from a wide variety of weight configurations,depending on your individual horsepower and rpmrequirements.AMS5844 ROD BOLT UPGRADECrower’s AMS5844 rod bolt upgrade is availablefor all steel billet and titanium rods. Highlyrecommended for extreme duty rpmand endurance applications. Rated at280,000 p.s.i., these bolts are corrosionresistant, nonmagnetic and deliverultimate clamping capabilities for thehighest cycle life. Specify desired rod boltpart number when ordering.Proper bolt torque: Torque rod bolts to 10 ft lbs on both sides,then torque to proper spec with one pull.Upgrades: 280,000 p.s.i. rod bolts, specify #90842 for 3⁄8280,000 p.s.i. rod bolts, specify #90830 for 7⁄16182For technical support call 619-661-6477 (7am to 5pm PST) • 24 hour fax: 619-661-6466 • www.crower.com

<strong>Steel</strong> <strong>Billet</strong> <strong>Connecting</strong> <strong>Rods</strong>STEEL BILLET ROD WITH 12 POINT CAP SCREW BOLTUnquestionably the most critical part of a high performance, internal combustionengine is the connecting rod. <strong>Connecting</strong> rods support the primary tension loadscaused by engine operation in each revolution or cycle of the crankshaft. Therefore,it is of utmost importance that the rods you choose to put in your engine are madefrom only the finest quality materials, manufacturing methods and fastening systemsavailable on the market. For over 30 years, Crower has beenmeeting this challenge by using the finest quality steel inthe production of our steel billet connecting rods. Every rodis fully CNC machined to remove all surface imperfections,100% magnaflux inspected, checked for hardness and thenmachined to finalize the exact tolerance within 0.0001" of aninch. Each set of rods is fully balanced and then shot peenedto achieve the ultimate in strength and reliability. Choosefrom premium H-11 tool steel rod bolts or available as anupgrade, AMS5844 bolts.An assortment of computerdesigned beams are availablefor different horsepower andweight requirements.Crower’s RBT beam featuresa radius beam design forthe utmost in strengthcapabilities while reducingoverall weight of the rod forimproved throttle response.Drilled and chamferedpin oil hole onCrowerods providesadditional oil at pin endto prevent galling.Available in aluminum/bronze bushed orpressed fit pin.Pin boss dynamicsare critical whendesigning a highperformanceconnecting rod. Tomaintain troublefreeoperation,Crower beefs up thepin eye area.CROWER H-BEAM DESIGNHollow dowel alignmentfastening system providespositive cap alignment and“no hassle” removal.Integrally threaded beamcan be made to acceptbolt diameters of 5⁄16, 3⁄8and 7⁄16.Deep, double-ribbedcap guaranteessuperior strengthand reliability at highengine rpm.Only Crower offers you, the engine builder,the choice of “I-Beam or H-Beam” design.AMS5844 ROD BOLT UPGRADECrower’s AMS5844 rod bolt upgrade isavailable for all steel billet and titaniumrods. Highly recommended for extremeduty rpm and endurance applications.Rated at 280,000 p.s.i., these bolts arecorrosion resistant, nonmagnetic anddeliver ultimate clamping capabilitiesfor the highest cycle life.

Both feature12-point heads.MAXI-LIGHT DESIGNCROWER “H-BEAM” CONNECTING RODSAlthough Crower is known mostly for it’s “I-Beam” rods, we also build a varietyof European influenced “H-Beam” designs as well. The thicker cross sectionsof the H-Beam are better suited for the EDM oil hole that runs the length ofthe beam delivering added oil to the pin. Weights are equivalent to Crower’sstandard “I-Beam” billet rod. Specify H-Beam when ordering.
