The Rancho RS9000XL 9-position adjustable series delivers nine levels of performance to on- and off-road trucks, SUVs and Jeeps. 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. Engineered and manufactured in the U.S., all RS9000XL series units are covered by a Limited Lifetime Warranty. Rancho – a popular brand of suspension, shocks and more worldwide – was born in the 1950s in Long Beach, Calif., as Rancho Jeep Supply, and quickly grew into a thriving off-road and performance suspension components manufacturer. In 1985, Rancho launched what would later become its best-selling shock absorber: the RS5000. Rancho continued to grow and add fully engineered, industry-leading shock absorbers – like RS9000XL, Loaded quickLIFT, Pro Series and more – plus suspension systems to one of the world's most recognizable and technologically leading brands. Rancho suspension systems, shock absorbers, accessories and other related products deliver rugged performance for work and play in any on - or off-road environment.
