Rancho 99-18 Chevrolet Pickup / Silverado 1500 1/2 Ton Rear RS5000X Shock

The 16mm nitro-carburized piston rod on this Rancho RS5000X shock absorber is built to resist scuffs and corrosion, setting a solid foundation for improved suspension performance. This shock is designed to fit a range of popular trucks, including the Chevrolet Silverado 1500 from 1999 to 2018, the 2007 Chevrolet Silverado 1500 Classic, and the 2019 Chevrolet Silverado 1500 LD, as well as comparable GMC Sierra models. It's a well-built option for drivers looking to enhance their vehicle's on- and off-road handling.

Rancho engineers these shocks with a unique valving system and an application-specific piston that works to control shock motion more effectively. The large twin-tube body is filled with all-weather fluid, allowing it to operate cooler and maintain control even in extreme temperatures ranging from -40 to 248°F. This helps reduce damping performance fade and foaming, ensuring consistent performance. For added comfort, a polyurethane rebound bumper and rubber bushings absorb ride harshness, while the fluon-banded piston enhances responsiveness to changing road conditions for a smoother overall ride.

Double-welded loops at stress areas and a 35mm sintered iron piston contribute to the shock's structural integrity and durability. The Progressive Engagement Valving is custom-tuned for each vehicle application to help minimize initial impacts at low speeds, leading to a less jarring experience. This shock absorber comes with Rancho’s Limited Lifetime Warranty, offering peace of mind with your purchase.
