Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a 9-position knob at the base of the shock body. Simply turn the dial to your desired setting, with “1” being the softest and “9” being the firmest.

Will these shocks lift my Plymouth Trailduster?
No, these shocks do not create lift. They are specifically valved and sized to function correctly on vehicles already equipped with a 2.5-4 inch suspension lift.

Is any special maintenance required for the adjustment knob?
It is recommended to occasionally turn the knob through its full range of settings to keep the internal mechanism free of debris, especially after off-road use.
