how to adjust rear shocks on rocker c
#1
#3
Use the SPANNER WRENCH (Part No.
94455-89) and extend or compress the springs to the
rider’s desired position. Mark the adjuster plates so you
adjust both springs to the same position.
a. Turning the adjuster plates OUT (toward the locknut)
increases the spring preload to carry a heavier load.
b. Turning the adjuster plates IN (away from the locknut)
decreases the spring preload to carry a lighter
load.
Tighten the locknuts against the adjuster plates.

This is for an upgraded system, but is relatively the same.
SUSPENSION ADJUSTMENTS
Preload
NOTE
Adjust spring compression to compensate for motorcycle load.
1. Place a mark in the same position on the keeper plate of each shock.
2. Loosen the jam nut on each shock.
3. See Figure 3. Use the shock absorber spanner wrench (1) (Part Number HD-94455-89) to rotate each keeper plate (2) to release or compress the springs.
For heavier loads: Turn the keeper plates OUT (counter clockwise, toward the jam nut), to increase spring preload.
For lighter loads: Turn the keeper plates IN (clockwise, away from the jam nut), to decrease spring preload.
4. Adjust both shock absorbers equally, the same number of turns, and to the same position relative to the marks.
5. Tighten the jam nut against each of the shock-absorber keeper plates.
Ride Height
NOTE
Ride height is adjusted with the motorcycle suspended and a screw jack under the rear wheel to raise/lower the suspension.
1. Loosen the flanged locknut on the front of the frame bracket.
2. Turn the adjuster collar in the direction of the desired ride height.
To increase rear wheel travel and raise the height:
Turn the adjuster collar IN towards the shock end of the stub shaft.
To decrease rear wheel travel and lower ride height:
Turn the adjuster collar OUT towards the frame bracket.
NOTES
Longer shock length from the frame bracket to the shock eye
will equal lower motorcycle ride height. With this kit, ride height
is adjustable from 0.5 to 1.0 in. (12.7 to 25.4 mm). Each complete
revolution of the flanged nut equals approx. 0.140 in.
(3.55 mm) of ride height.
Adjust ride height according to rider preference. However,
when operating under heavy loads, the lowest ride height setting
with the minimum preload setting, may cause the rear tire
to contact the rear fender.
3. When the desired ride height has been reached, tighten the flanged locknut on the front of the frame bracket to 32-39 ft-lbs (43.4-52.9 Nm).
4. Repeat for the opposite shock.
NOTE
Equal settings are required on both shock absorbers to maintain handling.
