Frequently Asked Questions

How do I adjust the settings on these shocks?
The RS9000XL features an external 9-position knob located at the base of the shock body, allowing for manual tuning without the need for specialized tools.

Do these shocks create 4.5 inches of lift?
No, these shocks do not create lift. They are specifically valved and length-configured to function correctly on vehicles already equipped with a 4.5-inch rear lift kit.

What is the benefit of the larger shock body?
The increased 2.75-inch diameter allows for more oil capacity, which helps dissipate heat more efficiently than standard shocks, preventing performance fade during aggressive use.
