Rancho RS7MT 2.5-4″ Rear Lift Shocks for 1969-1991 GMC Suburban 1500 4WD
Part Number: 2xRS77112_n677
Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on lifted GMC Suburban applications. Utilizing a sophisticated monotube design, these shocks provide the precision and consistent damping required for 4WD vehicles equipped with 2.5 to 4 inches of rear lift. By separating the gas and oil with a floating piston, the RS7MT eliminates oil foaming and aeration to ensure stable performance during demanding off-road excursions or highway cruising.
Features
- Monotube Construction: A high-pressure nitrogen gas charge provides a lightning-fast response rate to ensure consistent damping over washboard terrain.
- Internal Floating Piston (IFP): The physical barrier between nitrogen and hydraulic fluid provides zero aeration to ensure fade-free performance during high-frequency cycling.
- Hardened Nitro-Churuck Shaft: A 14mm heavy-duty piston rod provides superior tensile strength and corrosion resistance to ensure long-term seal integrity.
- Application-Specific Valving: Custom-tuned shim stacks provide optimized rebound and compression to ensure a controlled ride for the GMC Suburban’s specific weight distribution.

Frequently Asked Questions
Will these shocks lift my GMC Suburban?
No, these shocks do not create lift. They are specifically configured to accommodate the increased travel requirements of a vehicle already equipped with a 2.5-inch to 4-inch suspension lift.
What is the benefit of a Monotube over a Twin-Tube shock?
Monotube shocks like the RS7MT dissipate heat more efficiently and respond faster to terrain changes because the single-cylinder design allows for a larger piston and higher gas pressure without aeration.
Are these shocks sold as a pair?
Yes, this SKU includes two (2) rear shocks, providing a complete solution for your vehicle’s rear axle.
