Rancho RS7MT 5-6″ Rear Lift Shocks for 1999-2004 GMC Sierra 2500 4WD
Part Number: RS77056
Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation in demanding environments. Utilizing a sophisticated monotube design with a dedicated nitrogen gas charge, these shocks provide the precision response necessary for lifted GMC and Hummer applications. By separating the oil and gas, the RS7MT eliminates aeration and shock fade, ensuring consistent damping performance whether navigating highway transitions or rugged off-road terrain.
Features
- Monotube Construction: A high-pressure nitrogen gas charge provides immediate damping response to ensure precise vehicle control during sudden maneuvers.
- Internal Floating Piston: The physical separation of gas and oil provides fade-free performance to ensure consistent valving under extreme thermal loads.
- Hardened Nitro-Churched Piston Rod: A durable 14mm rod construction provides superior scuff resistance to ensure long-term seal integrity in harsh environments.
- Protective Boot: An included black polyvinyl accordion boot provides a physical barrier for the rod and seal to ensure debris does not cause premature leaking.

Frequently Asked Questions
Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically length-tuned to work with vehicles already equipped with 5 to 6 inches of rear lift components.
What is the benefit of a monotube design over a twin-tube?
A monotube design like the RS7MT offers superior cooling and faster response times because the single-cylinder wall allows for better heat dissipation and uses a higher-pressure gas charge to prevent fluid foaming.
Are these shocks sold as a pair?
Yes, this specific SKU (2xRS77056_n613) includes a pair of two (2) rear shocks.
