REPARE THE VEHICLE
With the vehicle on a solid, level surface chock the front wheels. Remove the
negative battery cable. Raise the vehicle by the axle and remove the rear wheels.
After the removal of the wheels lower the vehicle so the axle rests on jack stands
rated to support your vehicles weight. Remove the jounce bumpers as shown in
Figure “C”. The jounce bumper bracket is held to the frame by a single small
tack weld on the outside of the frame. This weld can be broken and the bracket
removed by gripping with pliers and twisting off.

ASSEMBLE THE KIT
Select one air spring and one upper bracket from your kit. Insert the 1-1/2"
carriage bolt upward into square space in upper bracket. Attach the upper bracket
to the air spring using the 3/8”-16 flange lock nuts.
Tighten the air fitting securely
to engage the orange thread sealant. Position the fitting to point to the anticipated
location of the air inflation valves, see Figures "A" & "E".
Select one lower bracket
from your kit. Assemble the lower bracket assembly to the air helper spring using
the 3/8”-16 x 3/4" flanged hex bolt as shown in Figure "A".

NSTALL THE ASSEMBLY TO THE VEHICLE
Place the assembly on the vehicle by installing the upper bracket so that it lays
against the outside of the frame rail. Insert the carriage bolt in the upper bracket
in the existing hole in the frame rail from the jounce bumper removal. Attach
with a 3/8”-16 flange lock nut. The lower bracket will rest on the axle. Push the
lower bracket toward the leaf spring stack until it rests next to the leaf spring “U”
bolts.
Using the upper bracket as a template, drill a 7/16" hole in the side of the
frame rail. Before drilling, ensure that there are no electrical, fuel, or brake
lines on the opposite side of the mounting surface that can be damaged by the
drill. Inserting a piece of wood between the frame rail and any lines in the path
of the drill can help avoid damage to these lines. Using the previously drilled
hole, attach the upper bracket to the frame rail using a 3/8"-16 X 1-1/2" hex bolt
and 3/8"-16 flange lock nut.
Center the lower bracket on the jounce pad. Use the "J" bolts and 5/16"
flanged lock nuts to secure the lower bracket to the jounce pad as shown in
Figures "A" and "B". Using your fingers, tighten the flanged lock nuts on as far as
possible. While making sure that the lower bracket stays centered on the jounce
pad, tighten each nut two turns at a time with a wrench, switching to opposite nuts
to ensure that the bracket is mounted evenly on the jounce pad. After the
installation of the driver's side assembly is complete, secure the brake line to the
corner of the lower bracket, using a nylon tie, to avoid interference with the air
spring, refer to Figure "D".

NSTALL THE AIR LINE AND INFLATION VALVE
Uncoil the air tubing and cut it in two equal lengths. DO NOT FOLD OR KINK
THE TUBING. Make the cut as square as possible. Insert one end of the tubing
into the push-to-connect elbow fitting installed in the top of the air helper spring
as far as possible.
Select a location on the vehicle for the air inflation valves. The location can
be on the bumper or the body of the vehicle, as long as it is in a protected location
so the valve will not be damaged, but still maintain accessibility for the air chuck
see Figure "E". Drill a 5/16" hole and install the air inflation valve using two
5/16" flat washers per valve as supports see Figure "F". Run the tubing from the
air helper spring to the valve, routing it to avoid direct heat from the engine, exhaust
pipe, and away from sharp edges. Thermal sleeves have been provided for these conditions. The air line tubing should not be bent
or curved sharply as it may buckle. Secure the tubing in place with the nylon ties provided. Push theend of the air line tubing into
