Rancho RS5000X Rear Shock Absorber Set For Silverado / Sierra / Ram / Hummer H2

The core of this new and innovative shock from Rancho® is the unique rebound valving system and an advanced compression phase of the shock absorber. This proprietary process developed by the ride engineers at Rancho will elevate the overall handling and performance of your vehicle on and off-road.

Progressive Engagement Valving

The Rancho RS5000X series design includes progressive rebound and compression discs. At lower speeds or in the earlier stages of the shock’s travel, an eccentric disc in the valve shim stacks will engage the valving at lower frequencies, helping to control the energy of motion as the cycle of the shock increases or decreases in its action. When hitting a pothole, off-road trail obstacle or similar activity, Rancho’s Progressive Engagement Valving allows for early flow of fluid, helping to reduce harsh initial impacts and to control the flow of fluid in a progressive, gradual manner through the valving. During on- or off-road driving activities like washboarding or when travelling a rough fire road, the early flow of fluid helps to minimize a “rough” ride as the piston movement is able to glide through the initial travel motion of the shock with minimal ground impact or force. If needed, the Progressive Engagement Valving will further engage to maintain control and stability.

Tuned Compression Control Valve

The Tuned Compression Control Valve is a custom-tuned, clamped disc base valve that regulates fluid transfer during the shock’s compression cycle to help absorb impacts without disc flutter and to help maintain vehicle control in virtually any environment. The precision-tuned shim stacked valving allows the motion of the shock to work in harmony with the vehicle during on- and off-road driving.

Enlarged 2-1/4-inch Twin Tube Body

The RS5000X series features a 2-1/4-inch diameter shock body. A larger shock body allows for increased fluid capacity to operate cooler and to increase vehicle control and performance at varying speeds and terrains. The RS5000X series combines a larger shock body with all-weather fluid, allowing the shock to withstand internal temperatures between -40 and 248 degrees Fahrenheit.

Gas Pressurization of Shock

Each RS5000X shock is gas pressurized to 150 PSI.* The twin tube, gas pressurized shock has a variety of advantages including minimizing air-to-oil mixture that can cause foaming and shock fade. Gas pressurization also provides a mild boost of spring rate to the vehicle.

16 mm Nitro-Carburized Rod

Every Rancho RS5000X shock piston rod is strengthened through a nitro-carburizing process. From increased scuffing resistance to additional protection against corrosion, the process enhances the shock’s overall durability. Nitro-carburizing also is more environmentally friendly than the chroming process

Full-Displaced 35 mm Bore

The RS5000X’s 35 mm bore helps to provide heightened control of shock motion due largely to the expanded piston area. Full-displaced compression valving allows the piston to displace more fluid than traditional rod displaced valving.

1-3/8-inch Diameter Sintered Iron Piston

The sintering process forms objects from powders using atomic diffusion. The powdered material is heated to just below its melting point, fusing all of the particles together to create the piston. This process brings increased structural conformity to each Rancho RS5000X piston.
