Chevrolet Silverado 1500 1/2 Ton Shock Absorber - Rear - Rancho - RS9000XL - 1999–2019. The Rancho RS9000XL rear shock is a nine-position adjustable performance unit designed for drivers who want tunable damping for both street and off-road use.

Now in its fourth generation, the RS9000XL blends durability and adjustability. An easy-to-reach knob provides nine levels of damping so you can fine-tune firmness for towing, hauling or trail driving. The design includes integrated bottom mounts for added strength and a dual-component 2K paint finish to resist chips. The tri-tube body (up to 2.38") with all-weather fluid maintains control across a wide temperature range, and nitrogen charging reduces fade for consistent response during extended runs.

Features

• Nine-position external damping adjustment for on-road and off-road flexibility
• Tri-tube body with all-weather fluid, rated for -40 to 248°F operation
