ATTACHING THE LOWER BRACKET
1. Set the assembly on the axle with the tall, wide vertical leg of the upper bracket on the
outside of the frame rail. The lower bracket spacer sets just inboard of the jounce bumper
pad on the axle housing.
2. Some models may require prying the brake line slightly away from the axle so that the
axle clamp will not pinch the brake line.
3. Insert a carriage bolt (N) into the rearward hole in the lower bracket. Attach the bracket
using the axle clamp (P), flat washers (J), and lock nuts (O). Torque to 20 ft-lbs.
ATTACHING THE UPPER BRACKET
1. Align the air spring vertically and horizontally and clamp the upper bracket to the frame
rail using a pair of vise grips or c-clamp.
BEFORE DRILLING, BE SURE TO CHECK THE BACK SIDE OF THE FRAME RAIL FOR
BRAKE LINES, GAS LINES, OR ELECTRICAL LINES THAT MAY BE IN THE WAY. IT IS
NECESSARY TO MOVE ANY INTERFERING LINES PRIOR TO DRILLING.
2. Using the upper bracket as a template center punch and drill a 3/8” hole through the
outboard side of the frame rail and upper bracket (Figure 9).
CAUTION
Use hole in upper bracket as a
template to center punch and drill
3. Install one bolt (M), one flat washer (J), one oversized flat washer (K), and a lock nut
(O). Torque to 44 ft-lbs and leave clamp in place.
4. Do not use the existing jounce bumper holes in the frame rail. Instead, use the holes in
the upper bracket as a template along the bottom of the frame rail and center punch and
drill two 3/8” holes through the holes in the upper bracket. Do not attach to the frame
rail at this time. Remove the clamp or vise grips.
INSTALLING THE FRAME BRACE
1. It may be necessary to cut or trim off the plastic locator studs (on ’97 and new models)
before installing the frame brace.
2. Install the frame brace (F) with the access holes toward the bottom of the frame rail.
This is a tight fit and may require tapping with a hammer or mallet.
3. Align the access holes with the holes already drilled in the bottom of the frame. Using
a large screw driver or punch through the already drilled hole, push the frame brace
forward or backward until the holes are aligned.
