Step 5 – Rear arm and component installation
Rear arms
A. Prepare the rear of the vehicle for control arm and component installation by removing the following items: shocks,
sway bar links, coil springs, track bar, brake line brackets at the frame, e-brake cables at the body and the driver’s side
upper and lower control arms.
B. Pre set the lower rear Radius Long Arm™s to 41 3/4” center to center and install the coupler end into the frame
brackets with the supplied 9/16” bolt, flat and lock washers. Attach the rubber bushing end into the lower control arm
mount on the axle housing using the factory hardware. Do not tighten the rubber bushing until the vehicle is on the
ground to avoid bushing preload.
C. Set the upper control arm to an initial setting of 17” center to center, install the coupler end at the mounting point on
the lower arm with the supplied ½” hardware and the other end at the upper mount on the axle using the factory
hardware. (photo 22)
D. Repeat steps A – C on the passenger side.
E. The upper control arms may need to be to be readjusted after the installation is complete for proper pinion angle.

Rear track bar bracket and factory track bar (photo 23)
NOTE: With the installation of the rear track bar bracket you may notice that at ride height, the axle is
not completely centered under the chassis; this is intentional. The reason for such offset at ride height
is to allow for proper tire to frame, and/or control arm clearance. Centering the axle under the chassis
at ride height may cause the tire to contact the frame and/or control arm which may result in tire
damage or failure!
A. With the axle properly supported remove the driver’s side rear lower control arm from the frame and axle.
B. Place the new track bar bracket over the factory track bar mounting point on the axle while aligning the two 3/8” holes on
the back side of the lower control arm bracket. Loosely install the two 3/8” bolts, washers, and nuts thru the lower control
arm bracket and track bar bracket.
C. Install the 9/16x3.5” bolt thru the factory track bar location being sure to use the supplied spacer to keep the factory
bracket from collapsing. Tighten the two 3/8” bolts to 35 ft/lbs then tighten the 9/16” bolt to 90 ft/lbs.
D. Using the supplied 9/16x3” install the factory track bar into the new bracket. Install the nut on the back side near the coil
spring but do not tighten at this time.
Rear Bump stops, coil springs and sway bar links
A. Install the rear bump pads (RE1387) on the top of the axle using the supplied 3/8” hardware.
