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

Part Number: RS77119

Summary: The Rancho RS7MT Monotube shocks are engineered to provide high-performance handling and rapid heat dissipation for the US Postal FJ-8A. Utilizing a high-pressure nitrogen gas charge, these shocks eliminate aeration and oil foaming to maintain consistent damping during heavy-duty service cycles. This kit is specifically valved for 2WD applications at factory ride height, ensuring a precise, controlled ride that compensates for the unique demands of delivery vehicle duty cycles.

Features

• Monotube Design: A high-pressure nitrogen gas charge provides rapid response times to road transitions to ensure maximum tire-to-road contact.
• Hardened Nitro-Churyl Piston Rod: The heavy-duty 14mm rod construction provides superior tensile strength to ensure long-term durability under constant load.
• Internal Floating Piston (IFP): The physical separation of gas and oil provides fade-free performance to ensure consistent damping over washboard surfaces or stop-and-go routes.
• Sealing System: A specialized multi-lip seal provides an airtight barrier against contaminants to ensure a long service life in harsh environments.

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 dampers while providing improved performance at stock ride height.

How does the monotube design help with delivery routes?
The monotube design uses an internal floating piston to keep the oil and nitrogen separate, which prevents the oil from foaming during frequent stops and uneven road surfaces, maintaining a consistent ride all day.

Are these shocks sold as a complete set?
Yes, this specific SKU includes 4 shocks to refresh the entire suspension system of your vehicle.
