STEP 1 - PREPARE THE VEHICLE
With the vehicle on a solid, level surface chock the front wheels.
Raise the vehicle by the rear axle and remove the rear wheels. After
the removal of the wheels lower the vehicle so the axle rests on jack
stands rated for your vehicles weight. Make sure the negative battery
cable is disconnected from the battery.
STEP 2 - PREASSEMBLE THE KIT
Select one air helper spring from your kit and an upper bracket.
Align the studs on the air spring with the holes on the upper bracket
making sure the air inlet hole can be seen through the slot in the
upper bracket, see Figure "A". Use the 3/8"-16 flange lock nuts
to secure the upper bracket to the air spring. Install the air fitting
as shown in Figure "A". Tighten the air fitting securely to
engage the orange thread sealant. Point the elbow fitting in the
direction of the inflation valve location. Position the lower
bracket as shown in Figures "A" & "C" and fasten the lower
bracket to the air helper spring using a 3/8"-16 flange bolt
(finger tight). The lip on the lower bracket will face towards the
tire. See Figures "A" & "B".
STEP 3 - PRE-FIT MARK AND DRILL HOLES
Place the assembly on the driver’s side on top of the leaf stack
stradling the leaf spring retainer and inserting the 1" spacer as
shown in Figures "A" & "C". Visually align the air spring so
that it is as vertical as possible refer to Figures "A" & "B".
Place the upper bracket against the frame rail and use the holes
in the bracket as a template to mark the holes to be drilled in the
frame rail. The distance between the upper and lower bracket
should be 5"-6 1/2" as shown in Figure "C". Mark holes to be
drilled with a center punch and remove the air spring assembly.
Before drilling the holes make sure all electrical, brake and
fuel lines are cleared from the path of the drill. Damage to lines
can be avoided by inserting a piece of wood between the frame
rail and any lines in the path of the drill. Drill the four holes in
the frame rail using a 7/16" drill bit. See Figure "A".
STEP 4- INSTALLATION TO THE VEHICLE
After drilling the holes in the frame rail place the assembled air
spring back on the leaf stack making sure the lower bracket is placed
over the retainer (see Figure "A" & "C"). Install the 3/8"-16 x 1
1/2" hex bolts and 3/8" washers through the upper bracket holes
and the holes that were drilled in the frame rail. Next fasten the
upper bracket to the frame rail using the 3/8"-16 flange lock
nuts and special flat washers to the back side of the frame rail
refer to Figures "A" & "B". The next step is to attach the lower
bracket to the leaf spring assembly. Notice that the lower
bracket is angled with the arc of the suspension. Use the 1"
spacer placed between the lower bracket and the leaf spring
towards the front of the vehicle as shown in Figures "A" & "C".
Insert the 8" carriage bolts capturing both the 1" spacer and the
lower bracket, see Figure "A". The carriage bolts should
stradle the leaf stack, refer to Figures "A" & "B". Slide the
bracket straps onto the carriage bolts as to clamp the lower
