Step 1 – Front coil and component installation
A. With the vehicle and axle properly supported prepare the front end suspension component installation by removing the following
items; shocks, sway bar links (from the axle end only), and track bar. Loosen but do not remove the lower control arm bolts at
the axle, they will be replaced later with caster adjusting cam bolts. The factory shocks and track bar will not be reinstalled on the
vehicle.
B. Remove the brake line attaching screw at the frame and let the lines hang loose until later in the install. DO NOT remove the
brake lines or loosen the brake line fittings. Lower the breather hose clip on the shock tower approximately 3”.
C. Lower the axle and remove both coil springs.
D. Place the front bump stop on the center of the lower spring mount on the axle tube. Insert a center punch thru the center hole in
the bump stop and mark the hole to be drilled. Drill the marked hole to 5/16”
E. With the lower bump stop placed inside the new front coil spring, raise the small diameter end of the coil into the upper spring
bucket and over the lower spring cup and bump stop pad. Rotate the coil spring so the end of the coil properly sits in the factory
pocket and install the supplied 3/8” self tapping bolt thru the bump stop and secure to the axle. (Photo #1)
F. Raise the axle towards the chassis and install the new shock absorbers. (Purchased separately)

Front Track bar
A. Set the track bar at an initial setting of 32 7/8”. Loosely install the bushing end of the track bar into the axle mounting bracket
reusing the factory bolt and nut.
B. Using the factory bolt and supplied misalignment sleeves install the rod end into the factory track bar mount at the frame. Do not
fully tighten the track bar at this time, the axle center needs to be checked after completion of the entire system and the vehicle
is on the ground. The bend on the track bar will be with the elbow up to clear the front differential cover.
NOTE: It may be necessary to use a ratchet strap to pull the axle to the drivers side and install the track bar. Otherwise wait
until the vehicle is on the ground under its own weight to install the track bar at the frame end. Moving the steering wheel back and
forth will assist in connection the track bar if the vehicle is on the ground.
