Insert the larger #308071 (O 5x1) O-ring onto the shock body,
until it seats around the shock body extension.

Lubricate the small #308070 (O 3.1x1.6) O-ring with a drop
or two of shock oil. Taking care not to rip or damage the O-ring,
slide it over the end of the shock rod.

Install the end-cap onto the bottom of the shock body. Lock it in
place by pressing it on, then turning it CW about 1/8 of a turn.
For easy assembly, use a #183010 HUDY Shock Assembly Tool.

Place the #308350 collar over the top pivot mount, and thread it fully onto the shock body.

Turn the shock upside down and pull the shock rod out to full extension. Release the shock end-cap by turning it CCW and
pulling it slightly away from the shock body. Let the shock “vent” for at least 10 minutes; excess oil should seep out the end
of the shock body. If the shock rod doesn’t retract slightly into the shock body, push it in by 1~2mm. Replace the end-cap.
Check the shock for proper operation. The shock rod must move in and out freely with only "hydraulic" dampening.
The shock rod should not extend out by itself when pushed in and released, nor should it be drawn into the shock body when
extended and released. If this happens, reopen the shock, refill with oil, reassemble, and repeat the bleeding procedure.

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.

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).

Fully extend the piston rod so the piston is at the bottom of the shock body.

Hold the shock upright and slightly overfill the shock body with shock oil.

Let the oil settle and allow air bubbles to rise to the top. Slowly move the
piston up and down until no more air bubbles appear. Add shock oil as necessary.

Pull the piston rod most of the way out of the shock body.

Place the rubber bladder on top of the shock body. Some oil should spill out.

Move the piston out very slightly so the bladder seals against the top of the
shock body.

Grip the top of the shock rod’s exposed thread
with side-cutting pliers.
Thread the ball joint onto the shock rod until
approximately 1mm of thread is exposed.
HINT: Pre-thread the ball joint using an M3 screw.
WARNING! Be careful not to pre-thread too far, since the ball joint may split or the plastic threads may strip out
