INSTRUCTION MANUAL BEFORE
Installation of Anti-Squat Kit
1
Raising Car
Raise rear of the vehicle by using a 4 post lift. Securely block the front wheels
of the vehicle. Do not remove the rear wheels during installation.
2
Support the Rear Section
Once the truck is on a 4-post lift, jack up the rear section of the truck. Support
the truck at the frame rails and not at the axle. Raise the rear until most of the
load is off the rear wheels. The wheels should still be touching the lift surface.
Use another jack to support the front ends of the trailing arms.
3
Remove Original Front Trailing Arm Mounts
Unfasten the large ¾” bolts holding the front ends of the trailing arms. Lower the
jack supporting the trailing arms and they should slide down from the bracket
mounts.
Each mount is secured with 6 factory rivets. Use an air chisel to remove the rivet
heads. Once the heads are removed, you can punch the rest of the rivet out and
remove the original bracket from the truck.
4
Install Hotchkis Trailing Arm Mounts
Replace the original mounts with the Hotchkis Mounts. Mounting hardware is provided
to replace the rivets that were removed. Install the bracket as shown in the
diagram.
5
Reinstall the Trailing Arms
The Hotchkis trailing arm brackets have 4 holes to choose from. The lowest hole is
the same as the original. As you move up in holes, the angle of the trailing
increases by 1°. The higher the hole used, the more anti-squat you will get. You
may want to experiment with different holes to determine the best setup for your
truck. As a default you can install the trailing arm in the lowest hole.
You Hotchkis kit utilize spacer washers to give the trailing arm some room to
articulate. Install 1 spacer on each side of the trailing arm. So each arm will
have 2 spacers used total. Install the new hardware. Fasten the large bolts, but
do not fully tighten at this time. You do not want to preload the bushings!

Optional Pinion Shim
We also include an optional shim in case you would like to change your pinion angle.
The shim will change your pinion angle by 5°. Depending on the ride height of your
truck and driveline angle, this shim may or may not be needed. The shim goes between
the rear end mount and the trailing arms. Use the included longer u-bolts when
using the shim and/or with our #18390 Rear Suspension Package.
Tighten Hardware
Lower all jacks and let the load rest on the wheels. Fully tighten the ¾” bolts at
the front of the trailing arms.
