Rancho RS7MT 0″ Lift Shocks for US Postal FJ-9 2WD

Part Number: RS77113

Summary: The Rancho RS7MT Monotube series is engineered to provide high-performance handling and stability for the US Postal FJ-9. Utilizing a high-pressure nitrogen gas charge, these shocks eliminate oil aeration to maintain consistent damping force during demanding delivery routes. This monotube design is specifically tuned to provide rapid response and precision control, effectively solving the issue of wallowing or unstable handling in utility-focused vehicles.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides a quicker damping response to ensure consistent control over varying road surfaces.
• Internal Floating Piston: The physical separation of gas and oil provides fade-free performance to ensure the shock maintains its damping integrity during high-duty cycles.
• Hardened Nitro-Carburized Rod: A 14mm piston rod provides increased durability and corrosion resistance to ensure a long service life in harsh environments.
• Sealing System: An integrated dirt wiper and multi-lip seal provide a clean operating environment for the internal components to ensure leak-free operation.

Frequently Asked Questions

Will these shocks lift my US Postal FJ-9?
No, these shocks are configured for 0″ of lift and are designed to replace the factory-length dampers while providing improved performance at stock height.

What is the benefit of a Monotube design over a standard shock?
The Monotube design features a single cylinder and a floating piston that prevents the mixing of oil and gas, which eliminates “shock fade” during heavy use.

Are these shocks protected against rust?
Yes, the RS7MT features a brushed zinc finish with a protective clear coat to resist corrosion and maintain its appearance in salty or wet conditions.
