Rancho RS5000X 4″ Rear Lift Shocks for 1999-2004 GMC Sierra 2500 4WD

Part Number: RS55297

Summary: The Rancho RS5000X series leverages advanced CrossTune technology to provide a significant upgrade over factory damping for lifted applications. Specifically configured for vehicles with 4 inches of rear lift, these shocks utilize a progressive engagement valving system that maintains smooth street comfort while delivering firm control during off-road excursions. The twin-tube gas pressurized design ensures rugged durability and dent resistance, making it an ideal solution for heavy-duty GMC and Hummer platforms.

Features

• CrossTune Technology: A unique progressive rebounding and compression disc system provides precise tuning across various terrains to ensure consistent ride quality.
• Nitrogen Gas Charge: High-pressure gas displacement provides reduced aeration and foaming to ensure fade-free performance in demanding conditions.
• Nitro-Carburized Piston Rod: A 16mm heavy-duty rod construction provides increased structural rigidity and corrosion resistance to ensure long-term seal integrity.
• Protective Boot: An included red polyvinyl accordion boot provides a physical barrier against debris and stones to ensure the longevity of the polished piston rod.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are extended-length dampers designed to work with vehicles that already have a 4-inch rear lift kit installed.

What is the benefit of the twin-tube design?
The twin-tube design allows the outer tube to take damage from rocks or debris without affecting the inner pressure tube, ensuring the shock remains functional in harsh off-road environments.

Do I need to purchase boots separately?
No, these Rancho RS5000X shocks include the signature red protective boots to keep the piston rods clean and protected.
