Rancho RS7MT 0-2″ Rear Lift Shocks for 1973-1986 Chevy K-20 4WD

Part Number: RS77118

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on vehicles with 0-2 inches of rear lift. Utilizing a sophisticated monotube design, these shocks provide the precise damping required to manage the heavy-duty suspension of the Chevy K-20. By separating the gas and oil with a floating piston, the RS7MT eliminates aeration and shock fade during demanding off-road use or heavy hauling. This upgrade transforms the ride quality of your classic 4WD, ensuring consistent control regardless of terrain intensity.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides a lightning-fast response rate to ensure consistent tire-to-road contact.
• 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-Chursh Rod: A 14mm heavy-duty piston rod provides superior tensile strength to ensure long-term durability in harsh environments.
• Sealing System: An integrated dirt wiper and multi-lip seal provide maximum protection against contaminants to ensure a leak-proof service life.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically valved and length-tuned to work with vehicles already equipped with 0-2 inches of rear lift.

What is the benefit of a Monotube design over a Twin-Tube?
Monotube shocks like the RS7MT dissipate heat more efficiently and use a floating piston to prevent oil foaming, which maintains consistent damping under heavy use.

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