Please read these instructions carefully and if you have any questions regarding

than happy to help.
THANK YOU FOR PURCHASING HOTCHKIS PERFORMANCE PRODUCTS
1) With the front wheels securely blocked, raise the rear of the vehicle to an adequate
working height, then support the vehicle / chassis / body securely with jack stands,
leaving the differential slightly supported with the jack.
2) Remove the rear wheels then remove the bolts that retain the lower shock absorber
mounts. If you have a Quad-Shock equipped car remove the nuts on the frame side
of the axle dampening shock and pull it from the pivot.
3) Gradually lower the differential far as possible ( be very careful not to over extend the
flexible brake line that runs from the chassis to rearend.). At this point there should be
little or no tension on the rear springs so they can be easily removed from the car
allowing the easiest and safest trailing arm installation possible. NOTE – pay
attention to the position of the cutoff spring end and be sure to re-install the springs
clocked in the same position as this will affect ride height and ride quality.
4) Unbolt the rear sway bar from the lower trailing arms and remove the bar.
5) Working on one side of the car at a time, remove the two trailing arm pivot bolts. The
front pivot bolt has very limited clearance between the muffler and frame rail, but can
be reached with a deep socket / ratchet combination. Remove the old trailing arm. Be
sure to only remove and install one trailing arm at a time, failure to do so will let the
rearend housing rotate and will make your installation much more difficult.
6) Clean the surface of the pivot points on the car checking to make sure there are no
rough edges that may tear into the new bushings. After apply a light coat of grease to
the outer surfaces of each bushing, slide the forward end of the new trailing arm up
into the position and reinstall the front pivot bolt. Note – for proper sway bar
installation – make sure the arms are positioned so that the stickers are towards the
outside of the vehicle – the arms are marked left and right.
7) Slide the rear of the trailing arm into place, reinstall mounting bolt and torque both
bolts to 70 ft./lbs. Note – locating and aligning the rear pivot bolt is a little tougher
and may require the use of a small pry bar or similar tool to line up the mounting
holes correctly.
Repeat steps 5 & 6 for the opposite side of the vehicle

8) Reinstall the rear springs, making sure of proper position. (See note in step 3)
9) Remove the nut clips from the sway bar and slip them over the holes on the tabs of
the new trailing arms with the threads towards inside of vehicle. Install sway bar onto
trailing arms with the ends on the outer sides of the tabs.
10) Raise the rearend assembly, reinstall the lower shock mounting bolts and the Quad-
Shock mounts (if required). Reinstall the rear wheels. Road test and recheck all bolts
after driving a few miles.
Note – 1983 to 1985 vehicles with the original anti-hop / slapper bars will require
removal of these bars, however, due to the increased rearend stability accomplished by
these trailing arms, traction and anti-hop ability will not suffer. For this same reason,
Quad – Shocks may also be safely removed from cars so equipped for increased tire
clearance.
