Rancho RS7MT 0″ Rear Lift Shocks for 1970-1995 GMC G-1500

Part Number: RS77113

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on both the GMC G-1500 and specialized AM General chassis. Featuring a sophisticated monotube design, these rear shocks provide the precise damping required to eliminate aeration and maintain consistent control during demanding cycles. Designed for vehicles at stock ride height, they offer a significant upgrade in responsiveness over traditional twin-tube units, ensuring a stable and composed ride regardless of load or road conditions.

Features

• Monotube Gas Pressure: A high-pressure nitrogen gas charge provides immediate damping response to ensure consistent tire-to-road contact.
• Internal Floating Piston (IFP): The dedicated oil/gas separator provides zero aeration to ensure fade-free performance during high-frequency cycling.
• Hardened Nitro-Churched Piston Rod: A 14mm heavy-duty rod provides superior scuff resistance to ensure long-term seal integrity and durability.
• OE-Style Mounts: Precision-engineered loop ends provide a direct-fit installation to ensure a secure connection to the vehicle chassis.

Technical Specifications

Fitment

• 1970-1995 GMC G-1500

Frequently Asked Questions

Will these shocks lift my GMC G-1500?
No, these shocks are configured for 0″ of lift and are designed to replace the factory-length dampers at stock ride height.

What makes the RS7MT better than a standard twin-tube shock?
The monotube design allows for a larger piston and better heat dissipation, which prevents the oil from foaming (aeration) during heavy use, maintaining consistent damping force.

Are these compatible with the US Postal FJ-9 models?
Yes, these units are specifically listed for the AM General FJ-9 chassis used in US Postal service applications within the 1970-1995 year range.
