Rancho RS7MT 2.5-4″ Rear Lift Shocks for 1981-1986 Chevy K10 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 a precise, consistent response that eliminates the fade often experienced with standard twin-tube shocks during aggressive driving. This specific configuration is optimized for the Chevy K10 4WD, ensuring a stable ride height and improved control both on and off the pavement.

Features

• Monotube Design: A high-pressure nitrogen gas charge provides a lightning-fast damping response to ensure consistent control over washboard terrain.
• Internal Floating Piston: The physical separation of gas and oil provides zero aeration to ensure fade-free performance during high-frequency cycling.
• Hardened Nitro-Carburized Rod: A 14mm piston rod provides superior scuff resistance to ensure long-term seal integrity and durability.
• OE-Style Mounts: Durable rubber bushings provide noise, vibration, and harshness (NVH) isolation to ensure a quiet and comfortable cabin environment.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically valved and sized to function with a vehicle that has already been modified with a 2.5 to 4 inch rear lift kit.

What is the benefit of a monotube shock over a twin-tube?
The monotube design features a single cylinder and a floating piston that keeps the oil and nitrogen separate, which prevents foaming (aeration) and allows the shock to run cooler and more consistently.

Are these shocks sold as a pair?
Yes, based on the SKU configuration, this product includes 2 rear shocks.
