EDELBROCK SHOCK

INSTALLATION INSTRUCTIONS

Please study these instructions carefully before installing your new Edelbrock shocks. If you have any questions, please call our

Technical Hotline at: 1-800-416-8628

, 7:00 am to 5:00 pm, Monday - Friday, Pacific Standard Time.

IMPORTANT NOTES:

• Any time you are working under a vehicle, be sure to use the proper jackstands 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 these shocks.

Return damaged shocks to

Edelbrock for any necessary service or repairs.

• 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.

• For good ride quality, tire pressure should be at original equipment manufacturer’s
recommended pressure. Failure to adhere to the recommended pressure will affect the
ride quality and void the Edelbrock Limited Warranty.

PLEASE READ THESE INSTRUCTIONS ENTIRELY BEFORE BEGINNING

• Proper installation is a must to realize the maximum performance improvements.
Follow these steps carefully.

USE THE RIGHT SHOCK FOR YOUR VEHICLE

• Use Edelbrock shocks only for the applications for which they are listed. Each shock
is specifically tuned for that vehicle’s weight, suspension geometry, and other
characteristics.

• Compare original shock mounting style and hardware with your new shocks before
starting installation. If original hardware is not reusable, it should be replaced with
OEM quality and style hardware.

• Shocks are tuned to vehicle manufacturer’s recommendation for tire pressure, not
necessarily the max inflation pressure listed on sidewall of tire.

INSTALLATION PROCEDURE (FRONT)

1. Raise the front end of the vehicle with a jack and jackstands
or a service lift. Loosen the lug nuts and remove the wheel
to access the shock and spring assembly.

2. Remove the nut(s) from the bolt(s) supporting the bottom of
the shock assembly, but leave the bolt(s) in place for now.

NOTE: On some applications, it may be helpful and/or
necessary to unbolt the sway bar to access the front
suspension. It is recommended that you only detach one
end of the sway bar at a time to simplify reinstallation.

3. Remove the nuts securing the top of the shock assembly to
the upper shock mount. You should now support the shock
assembly while removing the lower bolt(s). With all
fasteners removed, the entire shock & coil assembly can
now be removed.

4. Use a silver marker or a thin strip of tape to mark how the
spring is oriented in relation to the upper and lower shock
mounts. This will help you to properly align the spring
during reinstallation.

5. Use a compressor designed for coil springs to compress the
springs enough to loosen the upper shock absorber nut.

NOTE: Use extreme caution when working with and around
a compressed spring. Tool failure or accidents can unleash
forces capable of breaking bones and inflicting lethal
damage. Follow the instructions for your compressor
carefully.

6. Use a pair of vice grips or a proper shock socket to grasp the
flat end of the shock rod, then use a wrench to loosen the
shock absorber nut. DO NOT use an impact gun/wrench to
remove or install the upper shock nut on the Edelbrock
shock.
Warranty will be void if an impact gun/wrench is used.

7. The upper spring retaining plate, isolator, bump stop and
bushing(s) can now be removed, as well as the coil spring
itself. All of these components will be reused.

8. Remove the factory bump cap from the stock shock
assembly. The factory bump caps are pressed on, and will
require force to be removed. After removing the factory
bump cap, remove the lower spring perch from the stock
shock assembly. The stock lower spring perch can be
removed by displacing it away from the lower shock mount.

Depending on the amount of corrosion and presence of
debris, displacing the perch might require some effort. (This
step is not applicable to P/N 33180).

9. Use the snap ring (and the spring perch adapter if included)
that is included with the Edelbrock shock to set the desired
ride height on the Edelbrock shock. The upper snap ring
groove will yield a level ride height, while the lower groove
will set the vehicle to the factory ride height. (If there is a
third groove, the lowest groove will yield a lowered ride
height, while the middle groove will yield a stock height
setting). Install the stock spring perch (removed in step #8)
over the snap ring (and spring perch adapter if included) on
the Edelbrock shock.

10. Install the compressed factory coil spring around the
Edelbrock shock. Be sure to align the coil spring with the
shock and upper shock mount in the same orientation as it
was when it was removed.

11. Install the factory bump stop, spring retaining plate and
isolator along with the supplied hardware (if included). Use
anti-seize on the piston rod threads before installing the
upper shock nut. After the shock nut is tightened, ensure
that the spring retaining plate, coil spring and shock are
oriented as they were in step #4, then remove the spring
compressor.

12. Insert the shock and spring assembly into the upper shock
mount of the vehicle and start the nuts that will hold it in
place.

13. With the upper nuts supporting the assembly, maneuver the
shock assembly enough to insert and tighten the bolt(s) and
nut(s) for the lower shock mount.

14. Lower the vehicle so that the side of the suspension being
worked on comes to rest on a jack stand and allow the
suspension to compress to its normal ride height. Push
down on that corner of the vehicle a few times to cycle and
stabilize the suspension.

15. The lower bolt(s) and nut(s) can now be fully torqued to
factory specs.

16. Torque the upper spring retaining plate bolts/nuts to factory
specs.

17. Once you have verified torque on all the bolts, your
installation is complete and the wheel can now be
reinstalled.
