Installation Guide

Step 1: Removing the Jounce Bumper and Placing the Assembly on the Axle

Raise the vehicle and support it using safety stands so that the axle can be safely dropped away from the frame and the air spring assemblies can be put into position between the axle and frame.

Unbolt and remove the jounce bumper from the frame.

Attach the Upper mounting bracket A (item 1 in the parts list) to the frame. The slot hole in the middle should face toward the inside of the truck.

Place the assembly on the axle with the legs of the lower bracket on either side of the axle.

Step 2: Installing the Upper Bracket

Push the axle up so that the Upper mounting bracket B (item 2 in the parts list) can be bolted to the previous bracket (item 1 in the parts list). Then tighten the nuts.

Step 3: Installing the Lower Bracket

Adjust the assembly so that the air spring is perpendicular to the bottom and top mounting brackets without twisting.

Install the Fastening block (item 5 in the parts list) to the axle and Lower mounting bracket (item 4 in the parts list) with washers and lock nuts, then tighten the nuts.

Install the Lower mounting bracket with U-bolt (item 8 in the parts list) to the leaf spring.

Step 4: Installing the Heat Shield (Passenger's Side Only)

Install the heat shield to the exhaust port where it is closest to the passenger's side air spring.

NOTE: Must slide the air line protective sleeve over the air line near the exhaust port.

Step 5: Installing the Air Lines

Cut the air line appropriately and push the hose into the fitting, then pull back and make sure it's locked in place.

Install the inflatable valve in a selected location, usually on the license plate at the rear of the vehicle.

Check Air Tightness

• Put some air into the air spring bag and then spray a soapy solution on all connections and valves while checking for exiting air bubbles.
