Tow Kit Installation Instructions

Congratulations! You have just purchased the best engineered, highest

quality air suspension kit available on the market for your 2001-2010 GM

HD Pickup. When installed, this kit will allow complete control and

adjustability over your truck’s suspension. Be sure to fully read and

understand the instructions before starting your installation. As in any

suspension installation, it is the installer’s responsibility to assure a

correct installation. The installer is also responsible for providing

adequate clearances between vehicle components such as axles, shocks,

exhaust and mechanical linkages to ensure a safe and reliable installation.

WARNING

DO NOT EXCEED THE MANUFACTURER’S RECOMMENDED GROSS
VEHICLE WEIGHT RATING (GVWR).

1. Raise the vehicle until wheels are off the ground and support with jack stands under

the frame.

2. It is recommended that the truck’s bed be removed to allow working clearance in

and around the chassis. Use care to insure that the OEM lighting wire harness
connectors, fuel filler neck(s) and grounding straps are disconnected prior to lifting
the bed from its mounts

3. Support the rear axle with jack stands and remove the wheels.

Extreme caution should be used in the next few steps to prevent personal injury
and/or property damage. Make sure springs are unloaded before attempting to

remove them. Failure to do so can cause the spring to eject. Use a floor jack to find

the “neutral” position of the springs before removal.

4. Remove the leaf springs and the rear shackle assembly

5. Remove the secondary overload spring pads (if applicable)

6. Remove the rivets securing the factory leaf spring hanger to the frame. The holes in

the frame will need to be chased with a ½” drill.
