Rancho RS7MT 0″ Front Lift Shocks for US Postal FJ-8A 2WD

Part Number: RS77119

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on specialized vehicles like the US Postal FJ-8A. These front shocks feature a high-pressure nitrogen gas charge and a monotube design that eliminates oil foaming and aeration. Designed for stock height applications, they provide a precise, responsive ride that maintains stability under the demanding stop-and-go cycles of postal delivery routes.

Features

• Monotube Design: A 1.97-inch (50mm) body diameter provides increased fluid capacity to ensure cooler operating temperatures during heavy use.
• High-Pressure Nitrogen Charge: The 200 PSI gas charge provides immediate response to road inconsistencies to ensure maximum tire-to-road contact.
• Hardened Nitro-Carburized Rod: The heavy-duty piston rod provides superior scuff and corrosion resistance to ensure long-term seal integrity.
• Internal Hydraulic Bump: A built-in travel limit provides a secondary damping stage to ensure protection during full suspension compression.

Why Choose This Product?

• Engineering Advantage: The RS7MT utilizes a high-pressure gas charge to separate the oil and nitrogen, preventing the “fade” common in standard twin-tube shocks during repetitive cycling.
• Performance Benefit: Drivers will notice a significant reduction in body roll and a more “connected” steering feel, which is critical for the safety and longevity of utility vehicles.

Frequently Asked Questions

Will these shocks lift my US Postal FJ-8A?
No, these shocks are configured for 0″ of lift and are designed to replace the factory-length units while improving damping performance.

What is the benefit of a Monotube shock over a Twin-Tube?
Monotube shocks like the RS7MT react faster to bumps and dissipate heat more efficiently, making them ideal for vehicles that carry heavy loads or operate for long hours.

Is any modification required for installation?
These are designed as a direct bolt-on replacement for the OE front shocks on the AM General FJ-8A chassis.
