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

Part Number: RS77113

Summary: The Rancho RS7MT Monotube series is engineered for high-performance handling and rapid heat dissipation on the US Postal FJ-9. Featuring a high-pressure nitrogen gas charge and a monotube design, these shocks provide the precision and consistent damping required for heavy-duty service cycles. By separating the oil and gas with a floating piston, the RS7MT eliminates aeration and ensures a fade-free ride even under demanding conditions.

Features

• Monotube Design: A high-pressure nitrogen gas charge provides rapid response times to road inputs to ensure maximum vehicle stability.
• Floating Piston: An internal physical barrier between gas and oil provides zero aeration to ensure consistent damping performance during high-frequency cycling.
• Hardened Piston Rod: A nitro-carburized rod construction provides superior scuff and corrosion resistance to ensure long-term seal integrity.
• Application-Specific Valving: Custom-tuned internal shim stacks provide precise control for the FJ-9 chassis to ensure improved cornering and reduced body roll.
