Rancho RS7MT 5-6″ Lift Shocks for 1999-2004 GMC Sierra 2500 4WD
Part Number: RS77055
Summary: The Rancho RS7MT Monotube Shocks are engineered for high-performance handling and rapid heat dissipation on lifted GMC Sierra and Yukon XL 2500 models. Specifically configured for vehicles with 5 to 6 inches of suspension lift, these shocks utilize a high-pressure nitrogen gas charge to eliminate aeration during aggressive driving. The monotube design provides the precise damping response needed to maintain stability and control in both off-road environments and heavy-duty highway use.
Features
- Monotube Design: A 1.97-inch (50mm) diameter body provides increased fluid capacity to ensure cooler operating temperatures during off-road use.
- High-Pressure Nitrogen Charge: 200 PSI gas pressurization provides immediate response to surface changes to ensure consistent tire-to-road contact.
- Internal Floating Piston (IFP): The physical barrier between nitrogen gas and hydraulic fluid provides zero aeration to ensure fade-free performance in extreme conditions.
- Hardened Nitro-Carburized Rod: A heavy-duty piston rod provides superior scuff and corrosion resistance to ensure long-term seal integrity.

Why Choose This Product?
- Engineering Advantage: The RS7MT series utilizes a larger bore and high-pressure charge compared to standard twin-tube shocks, offering superior mechanical damping efficiency.
- Performance Benefit: Drivers will experience a significant reduction in body roll and “mushy” suspension feel, resulting in a more planted and confident driving experience on lifted applications.

Frequently Asked Questions
Will these shocks work on a stock height vehicle?
No, these shocks are specifically length-tuned for vehicles with 5 to 6 inches of lift. Installing them on a stock height truck may result in the shock bottoming out and causing internal damage.
Do I need to purchase boots separately?
No, these Rancho RS7MT shocks include protective black bellows boots to keep debris away from the oil seal and piston rod.
Are these shocks compatible with Quadrasteer models?
No, this specific kit is not compatible with vehicles equipped with the Quadrasteer package or electronic suspension systems like Z55 or Z95.
