Follow this tech tip to properly install pivot balls
into the top pivot and bottom ball joint.
Parts Needed:
• M3 x 16 SH screw
• M3 shim
Note that the composite parts have two sides,
noticeable around the pivot ball hole: one side
has a shiny fi nish, the other side has a regular
fi nish.
Install pivot balls into top pivot or
lower ball joint as shown, on the
proper sides.
Note that the lower pivot ball has
an extra shoulder.

After the shock is assembled you have to set the Shock Rebound.
1. To set the Shock Rebound, release the shock composite lower cap.
2. VERY SLOWLY do the following: Fully pull out the shock rod, push it back in fully, and then fully pull
it out once more. Repeat this procedure the following number of times to achieve the desired Shock
Rebound setting:
10 times - approximately 75% rebound (high rebound - suggested for very low traction track)
15 times - approximately 50% rebound (medium rebound - suggested for standard track)
20 times - approximately 25% rebound (low rebound - suggested for very high traction track)
During the Rebound Adjustment procedure shock oil will leak out of the shock body through the O-ring
on the shock rod... this is normal. During the Rebound Adjustment procedure DO NOT open the upper
shock cap.

Shock length adjustment:
It is VERY important that all shocks are equal length.
Fully extend the shock absorber and measure the end-to-end
length; we recommend using digital calipers to give an accurate
measurement. If a shock absorber is shorter or longer than others,
adjust the shock length by tightening or loosening the ball joint on
the shock rod.
Damping adjustment:
If you built the adjustable shocks, fully extend the shock rod and turn it
slightly to lock the piston in the shock body.
Turning the shock rod fully CCW aligns 4 holes in the pistons (softest
damping). Turning the shock rod fully CW aligns 1 hole in the
pistons (hardest damping). The shocks have four settings, each of
which can be felt by a slight "click".
Set all four shocks initially to position 3 (3 holes open): turn fully
CCW, then turn CW by 1 click.

3. After you have set the Rebound Adjustment, re-install the shock lower composite cap.
4. Check the Shock Rebound setting by pushing the shock rod fully into the shock body, releasing it, and
observing how far the shock rod extends by itself:
* 25% out of the shock body (low rebound)
* 50% out of the shock body (medium rebound)
* 75% out of the shock body (high rebound).
If the shock rod rebounds too much, return to Step 1 and repeat the procedure.
If the shock rod does not rebound enough, you will have to refill the shock with shock oil, and then repeat
the bleeding and Shock Rebound procedure.
