RANCHO RS9000XL SHOCK SET FITS 2001 - 2010 Chevy Silverado 2500HD 4WD 5-6in lift

This set includes 2 front and 2 rear RS9000XL series shocks. Recognized as the first nine-position manually adjustable ride control series in the off-road market, Rancho RS9000XL shocks deliver unprecedented control and performance. 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. Low-friction, self-lubricating seal retains gas and oil for quicker rebound and smoother compression while the long-lasting premium liquid metallic finish and polyvinyl protective boot ensures longer life. Up to 2.75-in. tri-tube body (application specific) filled with all-weather fluid allows for cooler operation, increased vehicle control and ability to withstand internal temperatures of -40 to 248°F. Polyurethane bushings enhance performance and durability while a boot protects the shock rod and oil seal.
