Rancho RS7MT 0″ Rear Lift Shocks for 1970-1991 Chevy G30

Part Number: RS77113

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on both the Chevy G30 and AM General FJ-9 platforms. Utilizing a sophisticated monotube design, these rear shocks provide the precision response required for heavy-duty applications and fleet service. By separating the gas and oil with a floating piston, the RS7MT eliminates oil foaming and aeration to maintain consistent damping performance under demanding conditions.

Features

• Monotube Design: A high-pressure nitrogen gas charge provides immediate damping response to ensure maximum vehicle control during sudden maneuvers.
• Internal Floating Piston: The physical barrier between nitrogen and hydraulic fluid provides zero aeration to ensure fade-free performance during extended drive cycles.
• Hardened Nitro-Chablis Rod: A heavy-duty piston rod provides superior scuff resistance to ensure long-term seal integrity in harsh environments.
• OE-Style Mounts: Application-specific bushings provide a direct-fit installation to ensure a quiet ride and reduced vibration transfer.

Frequently Asked Questions

Will these shocks lift my Chevy G30?
No, these shocks are configured for 0″ of lift and are designed to replace the factory-length shocks at stock ride height.

What is the benefit of a Monotube shock over a Twin-Tube?
Monotube shocks like the RS7MT dissipate heat more efficiently and respond faster to road imperfections because the larger piston area provides more consistent damping force.

Are these compatible with US Postal FJ-9 models?
Yes, these units are specifically listed for the 1970-1991 AM General FJ-9 platform used in postal applications.
