Step 10
Locate four 8-32 x 5/8” screws and 4 nylon lower suspension arm spacer. Use 1 thin and 1 thick nylon spacer
under each pad on the arms.
Pass a screw through the chassis and slide a nylon riser over the screw. Start threading the screw into the
lower suspension arm but do not tighten it. Pass another screw through the chassis and slide a nylon riser over
that screw. Start threading the screw into the other hole on the lower suspension arm. Tighten both screws.
Repeat on the other side.
Special Note:
In testing, we found we preferred to not use any suspension brace, strap or tube to connect the left and right
suspension assemblies. This was true on high traction carpet tracks to low bite asphalt tracks. You can add
or remove lower arm spacers to adjust ride height and to compensate for tire wear.
Locate two flex plates*, 2 flex plate pivot ball
housings w/ the pivot balls installed, and 4 2-56
button head screws.
1.Slide pivot ball housing through the flex plate so
the flex plate encloses the boss on the lower side of
the housing.
2.Pass the 2-56 screws through the pivot ball
housing from the top so they thread into the flex
plate.
