Frequently Asked Questions

How do I adjust the settings on these shocks?
The RS9000XL features a manual knob located at the base of the shock body. You can turn the dial by hand to any of the nine numbered settings to increase or decrease firmness.

Do these shocks provide the lift for my truck?
No, these shocks do not create lift. They are specifically configured for vehicles that already have a 1-inch to 2.5-inch suspension lift installed.

Can I use these on a stock height GMC K1500?
These shocks are designed for 1-2.5 inches of lift; using them on a stock height vehicle may result in bottoming out the shock, which can lead to internal damage.
