Rancho RS7MT 0″ Rear Lift Shocks for 1971-2003 Dodge B300, B350, B3500

Part Number: RS77113

Summary: The Rancho RS7MT series is engineered to provide high-performance handling and rapid heat dissipation for heavy-duty applications. Utilizing a sophisticated monotube design, these rear shocks are configured for 0-inch lift heights, making them an ideal upgrade for maintaining factory ride height while improving stability. The RS7MT’s high-pressure nitrogen charge significantly reduces aeration, ensuring consistent damping performance even during demanding cycles on your Dodge or AM General chassis.

Features

• Monotube Construction: A high-pressure nitrogen gas charge provides rapid heat dissipation to ensure consistent performance and reduced fade during heavy-duty use.
• Internal Floating Piston: The physical separation of gas and oil provides a precise damping response to ensure improved vehicle stability and control.
• Hardened Nitro-Chablis Piston Rod: A 14mm heavy-duty piston rod provides superior structural integrity to ensure long-term durability under harsh conditions.
• OE-Style Mounts: The application-specific mounting hardware provides a direct-fit installation to ensure a secure and rattle-free connection to the chassis.

Frequently Asked Questions

Will these shocks lift my vehicle?
No, these shocks are configured for 0-inch lift and are designed to replace factory-length units while providing a performance upgrade.

What is the benefit of a Monotube design?
Monotube shocks use a single-cylinder design and a high-pressure gas charge to dissipate heat faster than twin-tube shocks, preventing the oil from foaming (aeration) during heavy use.

Are these compatible with the US Postal FJ-9?
Yes, these units are specifically listed for the AM General FJ-9 model within the 1971-2003 year range.
