Summary: The Rancho RS9000XL series delivers industry-leading versatility for heavy-duty trucks and SUVs. Featuring a 9-position manual adjustment knob, these shocks allow drivers to instantly tune their damping profile from soft to firm to accommodate varying loads and terrains.

Frequently Asked Questions

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

Do these shocks create 6 inches of lift?
No, these shocks do not create lift. They are specifically valved and length-indexed to work with vehicles that already have a 5-6 inch suspension lift kit installed.

What is the benefit of the larger 2.75-inch body?
The larger body houses more oil, which helps dissipate heat faster than standard shocks, preventing “shock fade” during towing or off-road use.
