TOOLS AND SUPPLIES REQUIRED
• Floor Jack • Jack Stands • Wrenches (SAE and/or Metric) • Socket Set (SAE and/or Metric)
• Snap Ring Pliers • Spanner Wrench Set (QA1 P/N T114W or T115W) •Permatex® Anti-Seize Lubricant
DO NOT VOID YOUR WARRANTY!
Permatex® Anti-Seize Lubricant should be used on coil-over threads to prevent galling. Failure to lubricate the
coil-over threads with Anti-Seize prior to making ride height adjustments will cause damage to your shock
absorber and will void any warranty. All ride height adjustments must be made with the vehicle weight
completely unloaded from the suspension. Please call QA1 Technical Support with any questions.
Stocker Star Stock Mount shocks
QA1 Stocker Star shocks are designed to bolt into the factory shock mounting location on stock ride height vehicles. Shock
length should be verified if the ride height has been altered to ensure adequate shock travel. Refer to a repair manual for
shock installation for your specific vehicle. Note: The shock openings in the factory lower control arms may need to be
enlarged on certain applications to fit QA1 adjustable shocks (1967-1969 Camaro/ Firebird and 1968-1974 Nova).
Shocks with Spherical Bearing Mounts
Using a snap ring pliers, install a snap ring into one of the grooves in each shock eye followed by the spherical bearing and
the other snap ring. If pressing the bearing in, only press on the race of the bearing.
Coil-Over Shock Assembly
1. Thread the aluminum lock nut (shoulder up) and the spring seat adjuster
nut (shoulder up) down to the last thread - NO FURTHER. Now is a good
time to lubricate the threads of the shock with Permatex® Anti-Seize
lubricant.
2. QA1 highly recommends using Thrust Bearing Kit (QA1 P/N 7888-109) for
ease of adjustment. If the thrust bearing kit is used, coat both sides of the
washers with Permatex® Anti-Seize lubricant. Install the stainless steel
spring seat washer, followed by the bearing and finally, the second washer.
3. If the thrust bearing kit is not used, coat one side of the stainless steel
spring seat washer with Permatex® Anti-Seize lubricant. Place the
lubricated side of the washer down on the spring seat.
4. With the piston rod fully extended, slide the spring over the shock down to the spring seat adjuster and install the spring
cap. Note: xx401 and xx402 shock require 10” springs to be compressed about ½” for installation.
5. Make all ride height changes with the car off the ground and the suspension unloaded. Apply Permatex® Anti-Seize
lubricant before making any adjustments to the ride height. Once you have the ride height set, tighten the lock nut against
the spring seat adjuster using spanner wrench part number T114W or T115W.
Note: A four wheel alignment should be performed by a qualified alignment shop after any changes to the suspension system.

*M - Proper measurement of shock lengths, extended, compressed and shock ride height
are taken from the center of the top shock mount to the center of the bottom shock mount.
Compressed and extended lengths
measured from the center of loop(s)
and/or shaft shoulder and/or stud
shoulder.
If measuring from mounting surface
to mounting surface, deduct 5/8“ for
each mounting surface to allow for
the bushings.
• For proper measurement of other style shock mountings see diagram below.

Shock Valving Adjustments
QA1 shocks have 18 damping settings per knob. There are 6 clicks per revolution of each knob, and each knob has 3
complete revolutions. The knob set fully counter clockwise is the softest setting - start your adjustments from that point.
