Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a 9-position knob located at the base of the shock body. Simply turn the dial to setting 1 for the softest ride or setting 9 for maximum firmness.

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically configured for vehicles already equipped with a 2.5-inch to 4-inch suspension lift kit.

What is the benefit of the large 2.75-inch body?
The larger body allows for more oil capacity, which helps dissipate heat faster than standard shocks, preventing “shock fade” during towing or off-road driving.
