Rancho RS7MT 0″ Rear Lift Shocks for 1970-1991 GMC G-3500

Part Number: RS77113

Summary: The Rancho RS7MT Monotube series is engineered for high-performance handling and rapid heat dissipation on various terrains. These rear shocks are specifically tuned to provide a precise, responsive ride for your GMC G-3500, eliminating the “mushy” feel associated with standard twin-tube designs. By utilizing a high-pressure nitrogen gas charge and a floating piston, the RS7MT ensures consistent damping performance even during demanding cycles by preventing oil aeration.

Features

• Monotube Construction: A high-pressure 2-inch body provides rapid heat dissipation to ensure consistent performance during heavy-duty use.
• Internal Floating Piston: The dedicated nitrogen gas chamber separates the gas from the oil to provide zero aeration and lightning-fast response times.
• Hardened Nitro-Churuck Shaft: A heavy-duty piston rod construction provides superior resistance to scuffing and corrosion to ensure long-term seal integrity.
• OE-Style Mounts: Application-specific mounting hardware provides a direct-fit installation to ensure a secure and quiet connection to the chassis.

Frequently Asked Questions

Does this shock provide any lift to the vehicle?
No, these shocks are configured for a 0-inch lift height and are designed to replace factory-length shocks without changing the vehicle’s ride height.

What is the benefit of a monotube shock over a twin-tube?
A monotube shock like the RS7MT dissipates heat more effectively and uses a floating piston to prevent oil foaming, resulting in more consistent performance during aggressive driving.

Are these shocks sold in pairs?
Yes, this specific SKU (2xRS77113_n694) includes 2 shocks for the rear of your vehicle.
