I. Assembling the Air Spring 1. Install 90 degree air swivel fitting (D) to the top of the bellow. This fitting is precoated with sealant. Using an open-end wrench, tighten 1 and turns (Figures 1 and 2). IMPORTANT: Tighten on the metal hex nut only. Do not over tighten.

4. Set the assembly on the axle housing between the shock absorber bracket and the leaf spring (Figure 4). Loosely attach lower bracket and straps around the axle using carriage bolts (I), flat washers (G) and lock nuts (J) (Figure 4). NOTE for Non-Disc Brake Models Only: The brake line should be between the carriage bolt and the axle housing (Figure 6).
III. Installing the Air Line Air Line to Vehicle body or bumper Bellows 1. Choose a convenient location for mounting the inflation valves. Popular locations for the inflation valve are in the wheel well flanges, in the stowage area, under the body flange. NOTE: What ever the chosen location is, make sure there is enough clearance around the inflation valves for an air chuck.

No. Adding air springs will not change the weight ratings (GAWR, GCWR and/or GVWR) of a vehicle. Exceeding the GVWR is dangerous and voids the Air Lift warranty. Q. Is it necessary to keep air in the air springs at all time and how much pressure will they need? The minimum air pressure should be maintained at all times.
