Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features a manual dial at the base of the shock; simply turn the knob to your desired setting between 1 (softest) and 9 (firmest).

Will these shocks lift my GMC Suburban?
No, these shocks do not create lift. They are specifically valved and sized to function correctly on vehicles already equipped with a 2.5″ to 4″ rear lift kit.

Are these shocks nitrogen charged?
Yes, they are nitrogen gas pressurized to optimize performance and reduce aeration during rapid suspension cycling.
