12) Apply a thin layer of chassis grease to faces of bushings before installation.
13) Install HP trailing arms with the grease fittings facing down and the sway bar
mounting holes toward (offset) the rear of the car.
14) Install the new trailing arm by locating the front bolt first.
15) The trailing arm should then pivot smoothly on the chassis.
16) Pivot the arm and install the rear bolt. You may have to pry on the rear end
to install the longer arm, since the new Hotchkis arm in ½” longer then stock.
17) Once installed, torque all four bolts to 70 ft./lbs.
18) Install the rear sway bar using the supplied bolts.
19) Torque sway bar bolts to 35 ft./lbs.
20) Repeat procedure for other lower control arm.
NOTE: This is a really good time to replace the rear shock absorbers!

22) Take the two supplied aluminum shock spacers and install between the
shock and the rear end bracketry.
23) Tighten the shock nuts.

ADJUSTMENT OF THE PINION ANGLE USING THE HOTCHKIS
ADJUSTABLE UPPER CONTROL ARMS
1) Once it has been determined that the pinion angle in your vehicle needs adjustment, you
will then need to decide if that angle must be adjusted up or down.
2) To accomplish this, remove one stock upper control arm and measure the distance
between the mounting holes. (from center to center) Write this measurement down!
*NOTE
3) If the pinion angle needs to be adjusted downward, the upper arm hole-to-hole distance
must be shorter than it currently is in the car.
- The Hotchkis adjustable arms are pre-set at ½” longer than stock upper
arm center to center length. One rotation (360deg.) of the female end, will equal
approx. 1/2deg. One half of a rotation (180deg.) of the male end will equal approx.
1/4deg.
4) The Hotchkis adjustable arms can be shortened 3 turns shorter or 7/32” or .218”. If a
shorter arm is required, 1/4” of the threaded portion can be ground.
5) If the pinion angle needs to be adjusted upward, the upper arm hole-to-hole distance
must be longer than the current distance.
6) The Hotchkis adjustable arms can be lengthened 10 turns or 1/2” or .500”
