Installation Instructions
1. Raise the vehicle to a safe and comfortable working height by the frame with the axle
supported.
2. Remove the shock absorbers and the shorter leaf springs from the pack. Leave at least
two of the longest leafs in place. On this particular car we left 3 leafs and used a 2” lowering
block.
3. Bolt the eye to stud adapter to the
factory lower shock mount using the ½”
x 1 ½” carriage bolt, flat washer and
Nylok nut.
4. Fasten the lower Shockwave eye to
the eye to stud adapter with the ½” x 2
¼” bolt and Nylok nut.
5. Insert the stud on top of the
shockwave up through the factory
shock hole. Secure with a 12 mm
Nylok jam nut ..
6. Ride height on this Shockwave will
be approximately 15 ¾” measuring
from center eye to the bottom bushing
on the stud top.
7. Depending on how much you want
to drop the vehicle you may need to
install a lowering block.
8. Check air spring clearance
through full suspension travel.
Allowing the air spring to rub will
cause failure and it not a
warrantable situation.

The care and feeding of your new ShockWaves
1. Although the ShockWave has an internal bumpstop, DO NOT DRIVE THE VEHICLE
DEFLATED RESTING ON THIS BUMPSTOP. DAMAGE WILL RESULT. The internal
bumpstop will be damaged, the shock bushings will be damaged, and the vehicle shock
mounting points may be damaged to the point of failure. This is a non warrantable situation.
2. Do not drive the vehicle overinflated or “topped out”. Over a period of time the shock valving
will be damaged, possibly to the point of failure. This is a non warrantable situation! If you
need to raise your vehicle higher that the ShockWave allows, you will need a longer unit.
3. The ShockWave is designed to give a great ride quality and to raise and lower the vehicle. IT
IS NOT MADE TO HOP OR JUMP! If you want to hop or jump, hydraulics are a better choice.
This abuse will result in bent piston rods, broken shock mounts, and destroyed bushings. This
is a non warrantable situation.
3. Do not let the ShockWave bellows rub on anything. Failure will result. This is a non
warrantable situation.
4. The ShockWave product has been field tested on numerous vehicles as well as subjected to
many different stress tests to ensure that there are no leakage or durability problems. Failures
have been nearly nonexistent unless abused as described above. If the Shockwave units are
installed properly and are not abused, they will last many, many years. ShockWave units
that are returned with broken mounts, bent piston rods, destroyed bumpstops or
bushings, or abrasions on the bellows will not be warrantied.
