Description: $ImageURL1$Rancho Front & Rear RS5000X Gas Shock Absorbers for Silverado Sierra 1500HD 2500PART NUMBER: RS55370|RS55274BRAND: RanchoDESCRIPTIONRS5000X Shock Absorber - Front - RS55370RS5000X Shock Absorber - Rear - RS55274 Cross Tuned Technology 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.

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. Rebound Bumper: Each RS5000X series shock has a high-strength, polyurethane bumper that helps control the rebound motion during harsh driving conditions. The rebound bumper greatly reduces wear and tear during on- and off-road driving. When your shock rebounds from an obstacle at an excessive rate, the polyurethane bumper dampens the piston rod cycle at its peak point of travel. Black, Natural Rubber Bushings: The bushings used on the Rancho RS5000X series shocks provide additional ride harshness absorption and reduce transmitted road noise and suspension vibration to result in a smoother ride and longer life for shocks and related suspension components. Low-Friction, Self-Lubricating Seal: The low-friction, self-lubricating seal included in the RS5000X shock retains gas and oil to help prolong performance and allow for quicker rebound and smoother compression during the shock cycle. This seals provides an extra layer of defense against dirt and debris. Protective Boot: Each Rancho RS5000X series shock includes a red polyvinyl accordion protection boot, adding protection to the shock rod and oil seal during on- and off-road driving. Glass-Filled, Fluon Banded Piston: The RS5000X composite piston band provides smoother piston travel and greater responsiveness to changing road conditions. Each glass-filled band offers incredibly smooth operation within the shock absorber cylinder due to Fluon, a slippery glass and plastic material. Double-Welded Loops: Rancho engineers place extra emphasis on welded construction at stress areas - like mounting points - of the RS5000X shock. Each shock includes double-welded loops for added strength and durability. Full Fitment List: 2005-2007 Chevy Silverado 1500HD 4WD w/ 1-2.5" Lift Crew Cab - Exc.
