Rancho RS7MT 0″ Rear Lift Shocks for 1987-1991 Chevy R30, R3500 2WD Crew Cab

Part Number: RS77118

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation in demanding environments. Utilizing a sophisticated monotube design, these rear shocks provide the precise damping required for 2WD heavy-duty Chevy R30 and R3500 applications. By separating the gas and oil with a floating piston, the RS7MT eliminates aeration and shock fade to ensure consistent control during towing or spirited driving.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides a lightning-fast response to road inputs to ensure maximum tire-to-surface contact.
• Internal Floating Piston (IFP): The physical barrier between the gas and oil provides zero aeration to ensure fade-free performance under high-frequency cycling.
• Hardened Nitro-Churcked Rod: A 14mm piston rod provides superior tensile strength and corrosion resistance to ensure long-term seal integrity.
• OE-Style Mounts: Durable rubber bushings and high-strength hardware provide a direct-fit installation to ensure reduced NVH (Noise, Vibration, Harshness).

Frequently Asked Questions

Will these shocks lift my Chevy R30?
No, these shocks are configured for 0-inches of lift and do not provide any additional ride height; they are designed to replace factory-length dampers.

What is the benefit of a monotube shock over a twin-tube?
Monotube shocks use a single-cylinder design and a floating piston to prevent the mixing of oil and nitrogen, resulting in faster reaction times and better cooling.

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