Rancho RS5000X 2.5-4″ Lift Shocks for 1992-1998 GMC Suburban 2500 4WD

Part Number: RS55001 / RS55227

Summary: The Rancho RS5000X series leverages advanced Cross-Tuned technology to provide a significant upgrade over factory damping for lifted GMC Suburban 2500 applications. Engineered with a unique valving system, these twin-tube shocks manage the increased unsprung mass of larger tires while maintaining a smooth, controlled street ride. This specific set is configured for vehicles with 2.5 to 4 inches of suspension lift, ensuring the piston operates within the optimal range to prevent bottoming out or over-extension during off-road use.

Features

• Cross-Tuned Technology: A progressive engagement valving system provides custom damping curves to ensure stability during high-speed maneuvers and comfort on rough terrain.
• Twin-Tube Gas Pressure: The low-pressure nitrogen gas charge reduces oil aeration and foaming to provide consistent performance under heavy-duty cycling.
• 16mm Nitro-Carburized Rod: A heavy-duty hardened piston rod provides increased structural rigidity and resists scuffing to ensure long-term seal integrity.
• Glass-Filled Fluon Band: A specialized piston wrap provides a consistent seal between the piston and pressure tube to ensure rapid response to road irregularities.

Frequently Asked Questions

Will these shocks lift my GMC Suburban?
No, these shocks do not create lift. They are designed with extended lengths specifically to accommodate vehicles already equipped with a 2.5″ to 4″ suspension lift.

What is the benefit of the RS5000X over a standard shock?
The RS5000X features Cross-Tuned technology which uses a larger 35mm bore and specialized valving to better handle the weight of heavy-duty Suburban 2500 frames and larger aftermarket wheels.

Do these come with the red boots shown in pictures?
Yes, this set includes Rancho’s signature red protective boots to shield the piston rods from rocks, dirt, and debris.
