Step 9

Locate four 8-

32 x 5/8” screws and 4 thin and 4 thick nylon lower suspension arm risers.

Pass a screw through the chassis and slide a thin and a thick 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 
thin and a thick 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 the photo we are using alloy ride height spacers.  The kit includes black nylon spacers.  You will have to add 
or subtract spacers in order to achieve your desired ride height.  If you want to use the alloy spacers you can 
get a variety of sizes from

Locate two flex plates*, 2 Nickel Teflon plated Alloy 
pivot balls, 2 delrin pivot ball housings, 2 delrin
housing caps, 2 10-32 set screws* and 4 2-56 
button head screws.

1.

Place a pivot ball in a pivot ball housing with the 
shoulder on the ball facing down.

2.

Place a housing cap over the ball.

3.

Place the flex plate over this assembly.

4.

Pass the 2-56 screws through the pivot ball 
housing from the bottom up so they thread into 
the flex plate.

5.

Thread 10-32 set screw into the large hole on 
the flex plate above the housing cap.  Just get 
the 10-32 started into the flex plate for now as 
we will adjust it later.

The 10-32 set screw is there to adjust tension on the 
pivot ball so it can move freely but have zero play.

*Black flex plates and 10-32 set screws were used 
for photos.  The production links are natural G10 in 
color and the production screws are stainless steel.
