REPARE THE VEHICLE
Remove the positive battery cable. With the vehicle on a solid, level surface
chock the front wheels. 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. This installation assumes that there is no
load in the bed of the truck.
Your vehicle is equipped with rubber jounce bumpers. The bumpers are
attached to the frame directly above the axle. Remove these bumpers by unbolting
from the inside of the frame flange see Figure "C". This bumper will not be reused
with this kit.
The brake line bracket and brake-line/axle vent tube clip will need to be loosened
and removed to allow installation of the frame brace. The brake-line bracket is
attached to the top flange of the frame with two hex bolts. Remove the hex bolts
to allow the brake-line bracket to be moved far enough to facilitate installation of
the frame brace. The brake-line/axle vent tube clip is attached to the top of the upper
frame flange with a plastic pin. Remove the pin with a panel tool or screw driver
see Figure "C". Pull the clip out of the way of the frame brace.

ASSEMBLE THE KIT
Pre-assembly will begin with the left (driver's) side of the vehicle. All pictures
depict the installation on the left side of the vehicle unless noted otherwise. Install
the elbow fitting into the air spring. 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 Figure "A" & "F". Secure the upper bracket to the air
spring using 3/8" -16 flanged lock nuts. Next, select a lower bracket and secure to
the air spring using a 3/8" -16 x 3/4" flanged hex bolt see Figure "A". Be sure that
the lower bracket is attached to the air spring so that the bracket orientation is
perpendicular to the upper bracket. When the upper bracket of the air spring
assembly is attached to the frame rail, the lower bracket should rest in-line on top
of the axle without twisting the air spring see Figures "A" & "B".

NSTALL THE ASSEMBLY TO THE VEHICLE
Insert the left-side frame brace into the frame rail so that it straddles the jounce
bumper brace see Figure "A". Ensure that the frame brace does not pinch any
existing brake, electrical, or fuel lines that may be inside the frame rail. The brake-
line bracket and brake-line/axle vent tube clip will have to be held clear to allow
installation of the frame brace.
Place the air spring assembly on top of the jounce bumper pad on top of the
axle housing. Align the air spring over the axle. Slide the upper bracket onto the
frame rail and frame brace. Visually align the holes in the upper bracket with the
slots in the frame brace. It may be necessary to use a rubber mallet to force the upper
bracket onto the frame. Mark the frame with a center punch in the center of the holes
on the upper bracket. Use the upper bracket as a template to drill two 7/16" mounting
holes in the frame rail see Figure "A". Before drilling the holes make sure all
electrical, brake, and fuel lines are cleared from the path of the drill. In order to
prevent any damage to these lines it is recommended that a thin piece of wood be
placed between the frame rail and the existing lines. Attach the upper bracket with
the 3/8"-16 x 4" hex bolts and 3/8" -16 flanged hex nuts see Figures "A" & "B".
With the assembly attached to the frame rail, the next step is to attach the lower
bracket to the jounce pad on the axle housing. Center the lower bracket on the
jounce pad. Use the J-bolts and 5/16" -18 flanged lock nuts to secure the lower
bracket to the jounce pad see Figures "A" & "B". Spin the nuts on as far as
possible by hand. 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 left-side assembly is complete, re-attach the brake-line
bracket and brake-line/axle vent tube clip to the frame.
