Pacbrake 1988-2000 GM/Chevy Air Helper Spring Kit

Heavy Duty Air Helper Springs (double convoluted bags) are a great addition to your truck when you need to adjust the rear ride height when hauling a heavy payload. These helper kits mount between your axle and your frame directly above the rear-end of your truck. This bolt in kit is easy to install and easy to adjust just simple add air and level your ride.

Notice:

It is important before ordering the kit to measure the clearance between the jounce bumper mounting plate on the frame to the jounce bumper contact pad on the axle.

This clearance is important to ensure the correct height of air spring is installed.

Vehicles with less than 7-¼" between the jounce bumper mounting pad on the frame and the axle jounce bumper contact pad, must use a single convoluted air spring (Pacbrake kit 1PAC-HP10120).

Vehicles with more than 7-¼" between the jounce bumper mounting pad on the frame and the axle jounce bumper contact pad, must use a double convoluted air spring (Pacbrake kit 1PAC-HP10088 - this kit).
