DMI � BULLDOG REAR 

PRODUCT GUIDE

VOL. X

Welcome to the 2011 Bulldog Rear End / DMI Racing Components Product Guide. 

2010 was a very good year for Diversified Machine. 

It seems the release of our Bulldog CT-1 was just what the racers were waiting for. The response has 

been fantastic. It was really exciting everyday seeing who the next call would be looking to buy the 

product. It’s always a great feeling when a new racer or dealer joins the DMI family. It lets you know 

that the hard work and pride that we try to put into every product does not go unnoticed. As the year 

progressed, a real who’s who of racers were using the product. Some great CT-1 moments during 

the year was the first victory, courtesy of Don O’Neal in the Mastersbilt house car, sweeping the top 

4 positions at the Victoria 200 dirt modified race, winning the prestigious Eastern States 200 with Tim 

McCreadie and sweeping the Knoxville Late Model Nationals with Billy Moyer. See, in case you didn’t 

know, we’re kind of competitive here at DMI/Bulldog. We want our products to win as much as you want 

to win. It’s why we work so hard to not only build a great product but make it user friendly so you can 

spend your time before the main event picking the right tires and springs and not fighting with your quick 

change. Getting to victory lane, isn’t that what it’s all about? When you’re at the track in 2011 and see a 

late model or modified in victory lane, take a peak underneath, there is a good chance that it will have a 

Bulldog Rear under it. 

On the open tube side for 2010 we redesigned the “ironman” of the Bulldog lineup, the XR-1. We made 

it even more user friendly and incorporated many of the same ideas we used on our XR-2, the rear that 

shocked the industry when it was released for the 2009 racing season. Now for the 2011 season, we 

have redesigned the XR-2 to feature more strength in the snout area while maintaining the size and 

weight savings the design provides. Also for 2011, we have two new rears in the lineup, the SMXR-1 

for super modified racing and the much anticipated BB-1 for midget racing. We are very proud of both 

products and fell they are the nicest rears available in either market. 

We also spent a great deal of 2010 developing and testing new products for the DMI line. Some of the 

new items released during 2010 or for the 2011 season are the 2K11 line of u-joints, the “Big Unit” torque 

tube, fabricated tubular driveshaft, redesigned torque ball housings and open driveline components. 

Our minds never stop thinking of better ways to produce lighter, faster and safer components. We have 

also added stainless sprint car bumpers to our line and have become a stocking W.D. and authorized 

re-builder and re-valver for Pro Shocks. 

As you can tell, we’ve been busy. We’ve been busy because we feel an obligation to you, 

our customer, to continue to be the leaders in research and development of new racing 

components for short track racing. Sure, copying parts might be easier, but developing 

and producing new cutting-edge components is something only an American driven 

company like DMI/Bulldog can handle. It’s a job we take seriously. 

Have a safe and prosperous 2011.

The XR-2 was introduced for the 2009 season. Redesigned for 2011, 

the XR-2 features improved strength in the snout area with the 

addition of three ribs and added material on the internal casting. 

Stevie Smith, Gary Wright and Dale Blaney are some of the drivers 

who take advantage of the weight savings and performance offered 

by the XR-2. 

for 2011, the XR-2 is also available in aluminum. The aluminum 

version weighs less than 2 lbs. more than the XR-1 rear and is super 

strong! 

The space age design of the XR-2 puts it in a class by itself. One look 

at the XR-2 will make you say, “The future is now!”

There are a few important things you should know to get the most out of the CT-1 quick change. 

Here are a few tips. 

Oil 

Fill rear end through the large inspection plug on the right side. The oil should just cover the lower shaft. The rear 

is equipped with a fill level plug just below the large inspection plug. Fill rear until the oil runs out of the level plug. 

Please be sure to check the oil level often and after every gear change. We also recommend the use of a high 

quality gear lube, such as BullDog Blood by Champion Racing XP Synthetic or Joe Gibbs 75W110 Gear Oil. 

(We stand behind premature failure/pitting only if using BullDog Blood.) 

Torque Specs and Rear Settings 

Side Bell Nuts - 35 ft/lbs.

There are a few important things you should know to get the most out of the XR-1 or XR-2 quick change. 

Here are a few tips. 

Oil 

Fill rear end through the large inspection plug on the right side. The oil should just cover the lower shaft. The rears 

are equipped with a fill level plug just below the large inspection plug. Fill rear until the oil runs out of the level plug. 

Please be sure to check the oil level often and after every gear change. We also recommend the use of a high 

quality gear lube, such as BullDog Blood by Champion Racing XP Synthetic or Joe Gibbs 75W110 Gear Oil. 

(We stand behind premature failure/pitting only if using BullDog Blood.) 


The swivel coupler must be serviced every 4-6 races. Disassemble, clean thoroughly, replace worn out seal and 

o-rings and re-assemble. Pack splines liberally with Bel-Ray Assembly Lube available from DMI part # GR-600.

If you’re looking for the hub that stands out from the crowd, look 

to DMI’s Black Widow front Hubs. Increased strength in the web 

of the hub where you need it most and substantial weight savings 

around the perimeter make it not only the strongest, but also the 

lightest hub available. a new low profile threaded dust cap tops off 

this beautiful piece. If you liked the GoldStar front Hubs, you’ll love 

our Black Widows.

Squaring the Rear Axle: 

There are many different ways to square the rear end 

depending upon mechanical preference and comfort. This 

is one popular technique utilized by many professional 

teams. Place the rear end in the chassis and bolt up the 

torque tube. Set the axles on 6" blocks if it’s a standard 

chassis, 5" on the left side and 6" on the right if it’s a raised 

rail car. Secure the birdcages with spacers and the wheel 

nuts. Measure the distance from the rear round machined 

portion of the torque tube to the outer edge of the chassis 

by placing a straight edge vertically against the frame. 

Center the rear end by equalizing this distance on both 

sides of the car. This distance should measure between 10 

1/8" and 10 ¼". Now with the rear centered side-to-side, 

start with the right side and measure from the leading edge 

of the rear axle to the front edge of the motor plate. On a 

39" car this measurement is 37 5/8", 38 5/8" on a 40" car. 

Roll the axle forward or back on the blocks to achieve the 

correct distance. Once you have secured that distance on 

the right side check the left side. Ensuring that the rear is still 

centered in the frame and the right side measures correct, 

the left side may vary by as much as 1/8". This is generally 

left to lie as is. With the radius rods connected, place a level 

on the flat bottom portion of each bird cage and adjust the 

rods so that each cage is level with the bottom frame rail. 

Now bring your rear arms up to each bird cage flag and 

adjust each rod end so that the lower bird cage bolts slide 

freely through the cage and the rod end. Having completed 

this, recheck all of your measurements to ensure that 

nothing was moved during the previous processes. If all 

measures correct bring your jacobs ladder to the rod end 

or clevis and adjust the rod end or clevis in or out so that 

the bolt also slides freely. With these operations complete 

check your work by ensuring the torque ball is free and the 

jacobs ladder is not bound. Now you are ready for race 

height setup blocks and stops. 

Squaring the Front Axle: 

Set the front axle on 4" set-up blocks, or 3" and 4" if it 

is a raised rail car. Offset the axle 1" to the left side by 

adjusting the sway bar. This gives clearance to the left front 

torsion arm and combo steering arm. Measure 14" from 

the center of the right front torsion tube to the center of 

the axle on both sides. After roughing in the radius rods to 

this measurement, measure from the leading edge of the 

rear axle (still on 6" blocks) to the rear edge of the front 

axle on the rightside. After having gained this measurement 

we will set the lead. Check the left side the same way and 

adjust the rod length so that the left measurement is equal 

to or up to ¼" set back depending upon driver preference 

and size of track. With the axle now square we can adjust 

the caster. Place an angle fi nder on the right front steering 

arm. Adjust the top right front radius rod so that the angle 

reads anywhere from 6 to 10 degrees. Again this is driver 

preference, some drivers like more positive feel in the front 

end than others. With this complete you can drop the axle 

down to race height set-up blocks and adjust the stops. 

Don’t forget to set the tow. An 1/8" of tow out is generally 

the norm.
