Features

Frequently Asked Questions

How do I adjust the firmness of these shocks?
The RS9000XL features an external 9-position knob located at the base of the shock body that can be turned by hand to increase or decrease damping resistance.

Do these shocks provide the 4 inches of lift?
No, these shocks do not create lift. They are specifically valved and extended in length to function correctly on a vehicle that already has a 4-inch suspension lift installed.

Are boots included with the shocks?
Yes, this set includes Rancho’s signature red protective boots to shield the piston rod from debris and contaminants.
