Frequently Asked Questions

How do I adjust the damping settings?
The RS9000XL features a manually adjustable knob located at the base of the shock; simply turn the dial to your desired setting between 1 (softest) and 9 (firmest).

Does this shock provide the lift for my vehicle?
No, these shocks do not create lift. They are specifically configured for vehicles already equipped with a 2.5 to 4-inch lift kit to ensure proper suspension travel.

What is the benefit of the large 2.75-inch body?
The larger body increases oil capacity, which helps dissipate heat more effectively than smaller shocks, preventing “shock fade” during heavy use.
