Globally recognized as the first 9-position manually adjustable ride control series in the off-road market, the advanced RS9000XL series is ideal for on- and off-road use, towing and more. The adjustable damping enhances ride characteristics by counteracting the additional unsprung mass inherent in larger tire and wheel combinations.
