Rancho RS7MT 1.5″ Rear Lift Shocks for 1973-1990 GMC G-2500

Part Number: RS77118

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on both the GMC G-2500 and Toyota Land Cruiser FJ40. Utilizing a sophisticated monotube design, these rear shocks provide the precision response needed to eliminate aeration during spirited driving or heavy-duty use. Configured for a 1.5-inch lift, they offer a significant upgrade in damping control over stock twin-tube units, ensuring your classic rig maintains stability across varied terrain.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides a quicker damping response to ensure consistent control on rough surfaces.
• Internal Floating Piston: The physical separation of gas and oil 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 to ensure long-term durability against road debris.
• OE-Style Mounts: Precision-engineered end fittings provide a direct-fit installation to ensure a secure connection to the factory chassis points.

Why Choose This Product?

• Engineering Advantage: Unlike standard shocks, the RS7MT utilizes a high-pressure mono-chamber that reacts instantly to terrain changes without the lag associated with twin-tube designs.
• Performance Benefit: Drivers will experience reduced body roll and a more “planted” feel, particularly when the vehicle is loaded or navigating off-road obstacles.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically valved and length-tuned to work with a vehicle that has already been equipped with 1.5 inches of rear lift components.

What is the benefit of a Monotube over a Twin-Tube shock?
Monotube shocks like the RS7MT dissipate heat more efficiently and use a high-pressure charge to prevent the oil from foaming (aeration), resulting in more consistent damping.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS77118) includes two rear shocks to complete the rear axle of your vehicle.
