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:
Fig. 2
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 remove nuts.
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).
Fig. 1
3(c) Removal of lower sway bar end link
If the tool for unseating the sway bar from the
lower control arm is not available, the following
procedure may be used. (The sway bar end
link is held in place with a tapered seat).
In order to remove:
3(c)1 Loosen lower sway bar end link nut, do
not remove the nut completely.
3(c)2 Place jack under the nut.
3(c)3 Jack up and apply pressure to the nut.
3(c)4 Tap control arm with hammer.
(See Fig. 2).
3(d) Remove upper and lower bolts to remove
shock. It may need a little gentle persuasion
with a pry bar (See Fig. 3). Bolt should come
out by hand.
Fig. 3
Step 4 Removal of rear shock Step 7 Assembly of IAS shocks
4(a) Loosen upper and lower nuts.
4(b) In order to remove bolts, they may need a little
gentle persuasion with a pry bar. Bolt should
come out by hand. (See Fig. 3).
4(c) Shock will now come out through the top.
Step 5 Disassembly of coil springs from shocks
7(a) Adjust all four threaded spring collars to 2
3/8" from the top of collar. This will return
your Viper to the stock ride height. (Note:
Apply anti-seize compound to threaded
collars). The threaded collars may be
adjusted to raise or lower the ride height.
It is recommended to wait until after the
installation to settle the suspension and
determine the final ride height changes.
(See Fig. 6).
Fig. 6
A coil spring compressor is required to remove the
springs from shocks. 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).
Fig. 4
5(b) Move bump rubber up shaft in order to remove
spring seat retainer. (See Fig. 5).
Fig. 5
5(c) Release coil spring compressor carefully.
7(b) Install and tighten allen set screw with 1/8"
allen wrench. (See Fig. 7).
Fig. 7
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.
8(e) Align end of coil spring to lowest point on
spring seat before releasing the spring
compressor. (See Fig. 11).
Fig 11
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.
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
and 9/16" jamb nut (See Fig. 8).
Fig. 8
8(c) Front rod end has short threads.
(See Fig. 9).
Rear lower rod end Front lower rod end
Fig. 9
8(d) Screw rod end on with the supplied Loctite
applied, torque nut to 75 ft. lbs.
(See Fig. 10).
Fig. 10
Fig. 12
Fig. 12a
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.
