Rancho RS7MT 4″ Lift Shocks for 1999-2007 GMC Sierra 1500 4WD

Part Number: RS77268

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on lifted GMC Sierra and Yukon applications. Utilizing a sophisticated monotube design, these shocks provide the precise damping required to manage larger tire and wheel combinations across varied terrain. By separating the gas and oil with a floating piston, the RS7MT eliminates aeration and shock fade, ensuring consistent control during aggressive off-road maneuvers or highway transit.

Features

• Monotube Construction: A 2-inch diameter body provides high-pressure nitrogen gas charging to ensure rapid heat dissipation and consistent performance.
• Internal Floating Piston (IFP): The physical barrier between nitrogen gas and hydraulic fluid provides zero aeration to ensure fade-free damping in extreme conditions.
• Hardened Nitro-Coated Rod: A 14mm piston rod provides superior corrosion resistance to ensure long-term seal integrity and durability.
• Application-Specific Valving: Custom-tuned shim stacks provide precise rebound and compression control to ensure a stable, composed ride on lifted vehicles.

Frequently Asked Questions

Will these shocks lift my GMC Sierra?
No, these shocks do not create lift; they are specifically configured for vehicles already equipped with a 4-inch suspension lift kit.

What is the benefit of a monotube over a twin-tube shock?
The monotube design features a single pressure tube and a floating piston, which allows for better cooling and prevents the oil from foaming (aeration), resulting in more consistent performance.

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