Rancho RS5000X 1-2.5″ Rear Lift Shocks for 1988-1999 GMC K1500 4WD

Part Number: RS55190

Summary: The Rancho RS5000X series utilizes a sophisticated twin-tube gas pressurized design to provide exceptional durability and smooth street comfort for your GMC K1500. Engineered with a unique cross-tuned valve system, these shocks provide a custom-tuned ride that balances daily driving stability with off-road capability. Configured for 1-2.5 inches of rear lift, they serve as a robust solution for leveled or lifted trucks requiring improved damping control and dent resistance in rugged environments.

Features

• Progressive Engagement Valving: Custom-tuned internal valving provides a smooth transition between low and high-speed impacts to ensure consistent ride quality on varied terrain.
• Gas Pressurized Twin-Tube: The nitrogen gas-charged chamber provides reduced aeration and foaming to ensure reliable damping performance under load.
• 16mm Nitro-Carburized Rod: A heavy-duty hardened piston rod provides increased structural rigidity to ensure long-term seal protection and corrosion resistance.
• Protective Boot Included: The included polyvinyl accordion boot provides a physical barrier against debris to ensure the longevity of the shock rod and oil seal.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to accommodate vehicles already equipped with 1 to 2.5 inches of rear lift.

What is the benefit of the twin-tube design?
The twin-tube design is highly durable for off-road use; if the outer body is dented by a rock, the inner cylinder remains unaffected, allowing the shock to continue functioning properly.

Are these shocks sold as a pair?
Yes, based on the SKU configuration, this listing includes 2 Rear shocks to complete the rear axle of your vehicle.
