Rancho RS5000X 0-2″ Lift Shocks for 1969-1986 GMC K2500 4WD

Part Number: RS55151 / RS55118

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to provide a significant upgrade in ride quality for your GMC K2500. By incorporating a unique progressive engagement valving system, these shocks effectively manage the harshness typically associated with older leaf-spring configurations. Engineered for durability and smooth street comfort, they provide the ideal balance for daily driving and light off-road use while accommodating up to a 2-inch lift.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smoother transition during impacts to ensure consistent ride comfort on varied terrain.
• Gas Pressurized Twin-Tube: Low-pressure nitrogen gas charge provides a reduction in oil foaming and aeration to ensure fade-free performance during extended use.
• 16mm Nitro-Carburized Rod: Heavy-duty piston rod construction provides increased structural rigidity and scuff resistance to ensure long-term seal integrity.
• Protective Boot Included: Durable polyvinyl accordion boot provides a physical barrier against road debris and moisture 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 collapsed lengths to work with vehicles at factory height or those equipped with up to a 2-inch lift kit.

Do these come with everything needed for installation?
Yes, this full set includes all four shocks along with the required bushings and hardware for a direct bolt-on replacement of your factory units.

What is the benefit of the twin-tube design on this GMC?
The twin-tube design is exceptionally durable; the outer tube acts as a shield, meaning if the body gets dented by a rock, the inner pressure tube remains functional, ensuring you aren’t stranded on the trail.
