INSTALLATION OF HOTCHKIS PERFORMANCE
ADJUSTABLE TRAILING 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
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.
3) If the pinion angle needs to be adjusted downward, the upper arm hole-to-hole distance
must be shorter than the stock arm center-to-center distance.
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 stock arm center-to-center distance.
6) The Hotchkis adjustable arms can be lengthened 10 turns or 1/2” or .500”
- The Hotchkis adjustable arms are pre-set at stock upper arm
