NOTE
This instruction manual is for kits 88216 and 88128. The only difference between the two kits
is the bellows. The drawings depict a double convolute bellow, as found in kit 88216. But all
instructions and illustrations apply to kit 88128 as well, which uses a single convolute bellow.
The air springs will last much longer if they are not the suspension limiter in either compressor
or extension. The air spring compresses to 2.8” and extends to 9.1”. Regardless of load, the
air pressure should always be adjusted so that the Normal Ride Height is maintained at all
times. The shock absorber is usually the limiter on extension. If this is not the case, then the
use of limiting straps should be considered, in particular for vehicles that are used off-road.
COMPRESSED AIR CAN CAUSE INJURY AND DAMAGE TO THE VEHICLE AND
PARTS IF IT IS NOT HANDLED PROPERLY. FOR YOUR SAFETY, DO NOT
TRY TO INFLATE THE AIR SPRINGS UNTIL THEY HAVE BEEN PROPERLY
SECURED TO THE VEHICLE.
GETTING STARTED
1. The 88216 kit requires a minimum of 7.25” from the top of the jounce bumper strike plate
to the bottom of the frame rail. Before installation is begun, check for sufficient clearance.
If the measurement is less than 7.25”, then use kit 88128 (Figure 2).

2. Determine the Normal Ride Height. The Normal Ride Height is the distance between
the bottom edge of the wheel-well and the center of the hub with the vehicle in the “as
delivered” condition. In some cases, Normal Ride Height is not perfectly level.
a. Remove unusual loads and examine your vehicle from the side to ensure it is on a level
surface.
b. If necessary (in cases where your leaf springs are sagging badly), use a jack to raise
the rear end so that the vehicle achieves the original “as delivered” ride height.
