Rancho RS7MT 0″ Rear Lift Shocks for 1974-1983 Plymouth PB200, PB250

Part Number: RS77113

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on both the Plymouth PB-series vans and AM General FJ-9 chassis. Utilizing a sophisticated monotube design, these shocks provide the precision required to stabilize top-heavy utility vehicles during cornering and load changes. Designed for stock height applications, they serve as a direct-fit upgrade to eliminate the wallowing and fade common with standard twin-tube dampers.

Features

• Monotube Design: 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 aeration-free performance to ensure fade-free damping during extended drive cycles.
• Hardened Nitro-Churched Piston Rod: A heavy-duty 14mm rod provides superior scuff resistance to ensure long-term seal integrity and durability.
• OE-Style Mounts: Precision-engineered end fittings provide a direct-bolt-on installation to ensure a secure fit within the factory chassis locations.

Frequently Asked Questions

Will these shocks lift my Plymouth PB200?
No, these shocks are designed for vehicles at factory ride height (0″ of lift) and do not provide any lift on their own.

Are these compatible with the US Postal FJ-9?
Yes, these units are specifically validated for fitment on the AM General Model FJ-9 chassis used in US Postal service.

What is the benefit of the Monotube design over the original shocks?
The monotube design dissipates heat faster and eliminates oil foaming (aeration), which prevents the “spongy” feeling that occurs during long drives or heavy hauling.
