Rancho RS7MT 5-6″ Rear Lift Shocks for 2001-2007 GMC Sierra 1500HD

Part Number: RS77056

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on lifted applications. Featuring a high-pressure nitrogen gas charge and a monotube design, these shocks provide the precise damping required to manage the increased unsprung weight of larger tire and wheel combinations. This configuration is specifically valved for vehicles with 5-6 inches of rear lift, ensuring a stable, fade-free ride during aggressive off-road use or heavy hauling.

Features

• Monotube Construction: A 2.0-inch body with a high-pressure nitrogen gas charge provides rapid response times to terrain changes to ensure consistent damping performance.
• Internal Floating Piston: The IFP separates the shock oil from the high-pressure gas charge to provide zero aeration and prevent oil foaming during high-frequency cycling.
• Hardened Nitro-Coated Rod: A 14mm piston rod with a specialized coating provides superior corrosion resistance to ensure long-term seal integrity in harsh environments.
• Application-Specific Valving: Custom-tuned shim stacks provide the ideal balance of compression and rebound to ensure a controlled ride on vehicles with 5-6 inches of lift.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks are designed to be installed on vehicles that already have 5-6 inches of rear lift. They do not create lift themselves but provide the necessary travel for lifted applications.

What is the benefit of a Monotube shock over a Twin-Tube?
Monotube shocks like the RS7MT feature a single-wall design that allows for larger pistons and better cooling. This results in more precise valving and eliminates the “fade” experienced when shocks get hot during heavy use.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS77056_n571) includes two rear shocks for a complete axle installation.
