NOTE:
Please read thorough this manual completely before installing the air
spring kit on your vehicle.
STEP 1 — PREPARE THE VEHICLE
With the vehicle on a solid, level surface chock the front wheels.
Remove the negative battery cable.
Your vehicle is equipped with
rubber jounce bumpers. The jounce bumpers are bolted to the frame
above the axle. Remove the jounce bumpers from the vehicle.
STEP 2 — PRE-ASSEMBLE THE KIT
Select a lower bracket from your kit and determine which side of the
Figure
“A”
.
NOTE: The smaller side is for the gasoline engine axle and
the larger side is for Diesel engine axle
.
Select one air spring, bail
clamp and lower bracket from your kit. Place the bail clamp in the
correct position in the slot of the lower bracket for your vehicle. Install
the air spring to the lower bracket using the hole for your vehicle with
Please
see the lower right section of Figure “A”.
The bolt will be tightened
up in STEP 5.
STEP 3 — INSTALLING THE UPPER BRACKET TO THE
VEHICLE
Select an upper bracket from your kit. Install the upper bracket to the
Figure “A”
.
STEP 4 — INSTALLING THE ASSEMBLY TO THE VEHICLE
Position the lower bracket and air spring assembly from STEP 2 on
the axle as shown in
Figure “A”
. Put the large threaded stud though
the large hole on the upper bracket and the locating pin of the air
spring in the small hole on the upper bracket as shown in
Figure “A”
.
Make sure the aliment pin is in the locating hole before fasting
air spring to the upper bracket.
Fasten the air spring to the upper
bracket using ¾"-16 hex head nut and ¾" star washer. Fasten the
lower bracket to the axle housing using the bail clamp and the axle
securely to engage the orange thread sealant.
STEP 5 — INSTALLATION OF THE PASSENGER’S SIDE
ASSEMBLY
Before following STEPS 1-4 with reverse orientations for assembly
and installation of the passenger’s assembly, a heat shield will need
to be mounted between the upper bracket assembly and the top plate
of the air spring,
see Figure “B”
. Position the heat shield directly
between the closest heat source and the air spring. Ensure that the
heat shield will not interfere with normal operation of the air spring
or the vehicle’s suspension. Do not position the heat shield directly
above the axle, as it may contact the axle on full suspension travel.

(Step 5)
Important:
In order for the air spring
to function properly, there
must be a minimum of 1/2"
of clearance around the air
spring.
