INSTALLATION INSTRUCTIONS
FOR 1992-1995 VIPER SHOCKS

Catalog #33503

§ Please read these instructions entirely before beginning. Proper installation is a must to realize the
maximum performance improvements.

IMPORTANT NOTES:

§ Upon initial inspection, some new shocks may have a small amount of oil in the area of the seal. This is a
normal occurrence following manufacture and does not indicate a problem with your shocks.

§ Any time you are working under a vehicle, be sure to use the proper jack stands and tire chocks to prevent
any shifting or slipping of the car. Never use a jack only to support the vehicle while changing shocks.

§ Inspect shock brackets or mounting points before installation to make sure they are not broken or bent.

§ Do not attempt to disassemble the Edelbrock IAS shocks. Contact your point of purchase or Edelbrock

for any necessary service or repairs.

INSTALLATION INSTRUCTIONS

Step 1 Support Viper by frame with jack stands or

on a lift.

Step 2 Remove all four wheels.
Step 3 Removal of front shocks:

3(a) Loosen upper and lower shock nuts, but do not

remove the bolts at this time. (See Fig. 1).

3(b) If the lower shock nut is to rear, the lower sway

bar end link must be removed in order for the
bolt to have enough clearance for removal.
(See Fig. 1).

An aluminum block should be placed between arm and
hammer to minimize marking control arm, do not hammer
directly on the arm. It should only require a couple of
sharp taps with a hammer in order to pop from seat. Do
both left and right sides, and remo ve nuts.

springs from sh ocks. All proper safety precautions must
be followed. Consult the spring compressor
manufacturer's recommended instructions before
starting.

5(a) Compress the coil spring (see Fig. 4).

7(c) Slide threaded collar onto shock. It should

seat against the snap ring. Front shocks
are identified by part #33506, rear part
#34506. The part numbers are printed on
the side of the shock.

Step 8 Assembly of Front IAS shocks

8(a) Insert the coil spring with flat ground end

against the threaded collar spring seat.

8(b) Compress coil spring until lower seat has

enough clearance to install lower spring seat

Step 9 Assembly of Rear IAS shocks

9(a) Rear rod end uses the long threads. The

procedure of assembly is the same as the
front. (See Fig. 9).

Step 10 Installing IAS shocks

Reinstallation is reverse of removal.

10(a) Both front and rear may require a little gentle

persuasion with a long pry bar to push control
arms down in order to install bolts (See Fig. 12
and Fig. 12a). Shocks are mounted with the
body up & the rod end down. Do not torque
nuts at this time. Front lower bolts may be
installed with nuts to the front. This will make it
easier for reassembly.

10(b) Front sway bar end links may now be reinstalled. Install both left and right at the same time. After both

sides are in position, the end link to control arm nuts can now be torqued to 16 ft. lbs.

10(c) Important: After all four shocks are installed, place jack or jack stand under control arm to support

vehicle and load suspension at ride height. Torque the shock mounting bolts to 80-100 ft. lbs.
This must be done to pre-load the bushing in their proper position for safe and proper handling. This is a

very important step .

10(d) Install and torque wheels to 90 ft. lbs. After 5-10 miles, re-torque wheels to 90 ft. lbs.
