1.
Using a properly rated jack, raise the front of the vehicle and support the frame rails with jack stands. Ensure the jack stands are
secure and set properly before lowering the jack. NEVER WORK UNDER AN UNSUPPORTED VEHICLE. Remove the front wheels.
2.
With a fl oor jack under the front axle, slightly raise the axle housing to remove tension then loosen the lower shock mounts. Make
sure the axle is secure and well supported.
3.
Carefully remove the nuts from the upper and lower shock mount stems. Use caution to make sure that the axle doesn’t drop.
4.
CAUTION: As you lower the front axle watch for binding of the front drive shaft on the sway bar and overextension of brake lines
and diff erential breathers. Disconnect the sway bar and brake line brackets if necessary.
5.
Slowly and carefully lower the front
axle and remove the OEM shock. Continue
to lower the front axle until there is
suffi
cient room to install the longer ICON
shock.
6.
Fasten upper shock mounting location:
Install stem bushings and hardware as
shown in the diagram. Install the lower nut
and fasten until there are enough exposed
threads available to secure the upper jam
nut. Install jam nut until it is fl ush with the
top of the stem (DO NOT OVERTIGHTEN)
and torque to 50 ft-lbs while holding the
lower nut with a 19mm wrench.
Do not overtighten bushing assembly, as
this can lead to shock stem failure. Failure
caused by incorrect installation of stem
bushings and hardware is NOT covered
under ICON’s warranty policy.
