Rancho RS7MT 1.5″ Rear Lift Shocks for 1973-1986 Chevy C-20 2WD

Part Number: RS77118

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on both street and trail. Utilizing a sophisticated monotube design, these rear shocks provide the precision response required for vehicles with a 1.5-inch rear lift. By separating the gas and oil with a floating piston, the RS7MT eliminates aeration to ensure consistent damping performance during demanding driving conditions.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides a lightning-fast damping response to ensure maximum tire-to-road contact.
• Internal Floating Piston: The physical barrier between nitrogen and hydraulic fluid provides consistent valving performance to ensure zero aeration or foaming.
• Hardened Nitro-Carburized Rod: A 14mm piston rod provides superior resistance to scuffs and corrosion to ensure a long service life in harsh environments.
• High-Temperature Fluid: Specialized hydraulic oil provides stable viscosity across a wide temperature range to ensure fade-free performance during heavy hauling.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not provide lift. They are specifically valved and sized for vehicles that already have a 1.5-inch rear lift kit installed.

What is the benefit of a monotube shock over a twin-tube?
Monotube shocks dissipate heat more efficiently and use a floating piston to prevent the oil from foaming, which provides more consistent control under heavy use.

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