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.
DISASSEMBLY INSTRUCTIONS

2. Unbolt front upper shock mounts from inside the engine bay.
3. Raise and support the vehicle by the frame with jack stands on a stable surface and remove front wheels.
4. Remove the sway bar end links.
