Rancho RS7MT 5-6″ Lift Shocks for 2001-2010 GMC Sierra 2500HD

Part Number: RS77055

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on lifted GMC HD platforms. Utilizing a sophisticated monotube design with a nitrogen gas charge, these shocks provide the precise damping required to manage the increased unsprung weight of larger wheel and tire combinations. This setup is specifically configured for vehicles with 5-6 inches of lift, ensuring the piston remains in the optimal valving zone for both highway stability and off-road control.

Features

• Monotube Construction: A high-pressure nitrogen gas charge and large 46mm bore provide rapid response times to ensure consistent tire-to-road contact during high-speed transitions.
• Internal Floating Piston (IFP): The physical separation of the nitrogen gas and hydraulic fluid eliminates oil aeration and foaming to provide fade-free performance during aggressive driving or heavy towing.
• Hardened Nitro-Carburized Rod: A 14mm heavy-duty piston rod resists scuffing and corrosion to ensure long-term seal integrity in harsh environments.
• Vehicle-Specific Valving: Application-tuned damping rates provide the necessary rebound control to manage the geometry of 5-6 inch suspension systems.

Technical Specifications

Why Choose This Product?

• Engineering Advantage: Rancho’s monotube architecture offers superior thermal efficiency compared to standard shocks, preventing the “mushy” feel common during long-distance hauling.
• Performance Benefit: Drivers will experience reduced body roll and improved steering feedback, effectively neutralizing the top-heavy feel of a 6-inch lifted heavy-duty truck.

Frequently Asked Questions

Will these shocks fit a truck with stock suspension?
No, these shocks are specifically length-tuned for vehicles equipped with a 5-6 inch suspension lift system.

Does the monotube design help with towing?
Yes, the Internal Floating Piston (IFP) ensures that the damping remains consistent even under heavy loads, preventing the shocks from overheating and losing effectiveness.

Are the boots included with these shocks?
Yes, this full set includes protective dust boots to shield the nitro-carburized rods from road debris and contaminants.
