GETTING STARTED
Your vehicle may be equipped with a rear brake proportioning valve. Any type of load
assist product could affect brake performance. We recommend that you check with your
dealer before installing this type of product. If your vehicle DOES NOT have a rear brake
proportioning valve or is equipped with an anti-lock type brake system, installation of a
load assist product will have NO EFFECT on brake performance.
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.
1. Raise the vehicle and support the axle with jack stands, setting the jack stands as
wide as possible on the axle (Fig. 2).
2. Drop the axle or raise the frame up to make room for the assemblies to be put into
position between the frame and axle.
ASSEMBLING THE AIR SPRING ASSEMBLY
1. Set a roll plate (D) on both ends of the air spring (C). The radiused (rounded) edge of
the roll plate will be toward the air spring, enabling the air spring to be seated in both
roll plates (Fig. 3).
2. Install a 90° elbow fitting (E) to the top of the air spring. Tighten finger tight plus 1 1/2
turns. Be careful to only tighten on the metal hex nut. Do not overtighten (Fig. 3).
3. Install the upper bracket (A) onto the air spring assembly. Use slot “A” when installing
on the driver’s side and use slot “B” when installing on the passenger’s side. Attach
using two 3/8” bolts (G), lock washers (K), and flat washers (J or V). Leave the bolts
loose at this time (Figs. 3 & 4).
