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
Figure "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 Figure "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 Figure "A" & "C". Visually align the air spring so that
it is as vertical as possible refer to Figure "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 13/32" 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 Figure "A" and "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 Figure "A"
& "C". Insert (2) of the 7" carriage bolts capturing both the 1" spacer
and the lower bracket see Figure "A". The carriage bolts should
stradle the leaf stack refer to Figure "A" & "B". The 6" carriage bolts
will be used on the right side towards the rear of the vehicle of the
lower bracket were no spacer is used. The 6" carriage bolt closest
to the tire will be reversed to avoid contact with the brake caliper as
