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.
