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

Part Number: RS77056

Summary: The Rancho RS7MT Monotube series is engineered for high-performance handling and rapid heat dissipation on heavy-duty trucks and SUVs. Designed specifically for vehicles with 5-6 inches of rear lift, these shocks utilize a high-pressure nitrogen gas charge to separate the oil and gas, preventing aeration during aggressive driving. This monotube design provides the precision and immediate response required to manage the increased unsprung weight of larger wheel and tire packages on the GMC Sierra 2500HD and Hummer H2.

Features

• Monotube Design: A 1.97-inch (50mm) bore provides larger oil capacity and faster heat dissipation to ensure consistent damping performance under heavy loads.
• Internal Floating Piston (IFP): The high-pressure nitrogen gas charge separates the shock oil from the gas to provide zero aeration and fade-free performance.
• Hardened Nitro-Carburized Rod: A 14mm piston rod resists scuffing and corrosion to ensure long-term seal integrity and durability in harsh environments.
• Sealing System: An integrated dirt wiper and multi-lip seal provide a clean wiping action for the rod to ensure the internal hydraulic fluid remains uncontaminated.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically valved and sized to function correctly on vehicles already equipped with a 5-6 inch rear lift kit.

What is the benefit of a monotube shock over a twin-tube?
Monotube shocks like the RS7MT react faster to road imperfections and dissipate heat more efficiently, making them ideal for heavier vehicles and off-road use where shock “fade” is a concern.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS77056_n608) includes two rear shocks.
