Rolling Chassis With Tiger Rear - Mastering Your Rear - Drivetrain

The jam nut for the thrust block will get adjusted once the whole rearend is in place. The thrust block works by putting tension against the backside of the ring gear, keeping it in place. To adjust it, tighten it down until the block touches the backside of the ring gear, then back off one quarter turn and lock down the jam nut to the housing. Everything is held in place.

We assembled the new right side of the rearend completely before placing it onto the center section. You can clearly see our new birdcages from Bert. Yes, we didn't know Bert Transmission made birdcages either, but they're really nice looking parts and we can't wait to get on the track to let you know how they perform. We also decided to stick with our 007 hubs from Winters. We loved the way they performed over the last year and a half so there was no reason to change.

A soft hammer lends a little persuasion to get the birdcage lined up on the axle tube correctly.

With the rearend positioned under the chassis and the birdcage in the right spot, we set about connecting the lower bar to the birdcage. You can see the mounting point for the top bar just above the new brake rotor. Those rotors and the accompanying calipers are a subject for a different story. So stay tuned for that one.

The left side upper and lower bars are attached. Racers who run these cars know about the infinite adjustability which you can see in the wide variety of hole choices where the bars mount to the chassis.

The lower bar which goes from the bottom side of the birdcage to the frame sits in front (or to the outside) of the dummy shock.

Here's a view of the completed rearend which shows both the coilover shock, which is mounted to the rear of the axle tube, and the dummy shock in front.

The completed right side.

From this angle looking forward, you can see the lift arm assembly which features Port City Racing's aluminum lift bar. This bar cuts weight significantly while retaining plenty of strength.

In this closer look at the lift bar, you can see the J-Bar, also from Port City, behind it.

Our car has rod-ends from Aurora Bearing Company. This one attaches the J-Bar to the BSB mount on the chassis.

A little bit of creativity goes along way for a sponsor. Using an X-acto knife we cut out the Tiger from a decal and then highlighted the cast letters on the rear using a silver Sharpie.
