The Rancho RS9000XL RS999289 Suspension Shock Absorber is engineered to provide customizable ride control and enhanced durability for both on- and off-road applications. Featuring nine-position adjustable damping, it allows drivers to fine-tune the shock’s firmness to match varying terrains and load conditions. Its robust 2.75-inch tri-tube body increases fluid capacity, promoting cooler operation and consistent performance. The 18mm nitro-carburized piston rod offers superior resistance to scuffing and corrosion, ensuring long-lasting reliability. Additionally, the shock includes a polyurethane rebound bumper and graphite-filled, fluon-banded piston to absorb ride harshness and enhance responsiveness. Compatible with select Chevrolet Silverado 2500 HD, GMC Sierra 2500 HD, and Hummer H2 models, the RS999289 is ideal for vehicles with or without suspension lifts. Backed by Rancho’s limited lifetime warranty, this shock absorber delivers a balanced combination of comfort and control.
