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 your preferred setting (1 for softest, 9 for firmest).

Do these shocks provide the lift for my vehicle?
No, these shocks do not create lift. They are specifically valved and length-configured to work with vehicles already equipped with 0-3 inches of rear lift.

What is the benefit of the larger 2.75-inch body?
The increased surface area and oil capacity allow the shock to dissipate heat faster, preventing performance fade during heavy towing or spirited driving.
