Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a manual 9-position knob located at the base of the shock body. Simply turn the dial to a lower number for a softer ride or a higher number for firmer damping.

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically configured for vehicles with 0 to 1 inch of rear lift to ensure the piston operates within the correct travel range.

What is the benefit of the larger 2.75-inch body?
The increased oil capacity allows the shock to dissipate heat more effectively than standard shocks, which prevents “shock fade” during heavy towing or off-road use.
