Rancho RS7MT 2.5-4″ Rear Lift Shocks for 1969-1980 GMC K1500 4WD

Part Number: RS77112

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on vehicles equipped with 2.5 to 4 inches of rear lift. Utilizing a sophisticated monotube design, these shocks provide the precision response required for both technical off-road trails and stable highway towing. By separating the gas and oil with a floating piston, the RS7MT eliminates aeration and shock fade, ensuring consistent damping performance in the most demanding environments.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides a faster damping response to ensure precise vehicle control during sudden maneuvers.
• Internal Floating Piston (IFP): The dedicated dividing piston provides a physical barrier between gas and oil to ensure zero aeration and consistent performance.
• Hardened Nitro-Churched Piston Rod: A 14mm heavy-duty rod provides superior resistance to scuffs and corrosion to ensure a long-lasting seal life.
• Integrated Dust Boot: A protective bellows-style boot provides a shield against road debris and mud to ensure the internal seal remains free of contaminants.

Frequently Asked Questions

Will these shocks lift my GMC K1500?
No, these shocks do not create lift. They are specifically configured with the correct extended and compressed lengths to work on vehicles already equipped with a 2.5-4″ lift kit.

What is the benefit of a monotube design?
The monotube design allows for a larger piston area and better heat dissipation compared to twin-tube shocks, which prevents the oil from foaming (aeration) during aggressive driving.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS77112) includes a pair of two rear shocks for a complete axle installation.
