Rancho top of the line RS9000XL, 9 way adjustable, shock absorbers are ideal for on and off-road use, towing, and for vehicles with larger tires. The adjustable dampening enhances ride while counteracting suspension forces caused by lift kits and larger than stock tires. The RS9000XL is globally recognized as the first commercially available 9-way adjustable shock and is backed by Rancho's 90 days Free Ride Offer and a limited lifetime warranty.

The Rancho RS9000XL is equipped with nine levels of performance. Levels 1 - 3 are the softest settings, perfect for a supple ride and extremely slow speed flexibility. Levels 4 - 6 are the choice for daily driving and control, with similar ride characteristics as the RS5000X series shock. Levels 7 -9 are excellent for towing and maximum control during fast off-road situations. This all in one shock allows for a 400% change in control from softest to firmest, making it the best choice for those that use their vehicles in varying driving situations.
