Rancho RS7MT 0″ Front Lift Shocks for 2017-2020 Ford F-450 / F-550 Cab & Chassis

Part Number: RS77042

Summary: The Rancho RS7MT series is engineered for high-performance handling and rapid heat dissipation on heavy-duty Ford work trucks. Utilizing a sophisticated monotube design, these shocks provide the precise damping response required for the F-450 and F-550 Cab & Chassis platforms. By separating the gas and oil with a floating piston, the RS7MT eliminates oil aeration and shock fade during demanding towing or hauling cycles.

Features

• Monotube Design: A high-pressure nitrogen gas charge provides immediate damping response to ensure consistent control on uneven terrain.
• Internal Floating Piston (IFP): The physical barrier between nitrogen and hydraulic fluid provides aeration-free performance to ensure fade resistance under heavy loads.
• Hardened Nitro-Churuck Rod: A heavy-duty piston rod construction provides superior scuff resistance to ensure long-term seal integrity in harsh environments.
• Application-Specific Valving: Custom-tuned shim stacks provide optimized rebound and compression strokes to ensure a balanced ride for Cab & Chassis configurations.

Frequently Asked Questions

Will these shocks lift my Ford F-450?
No, these shocks are configured for 0-inches of lift and are designed to replace the factory-length dampers without changing ride height.

What is the benefit of the RS7MT monotube over a standard shock?
The monotube design dissipates heat more efficiently and uses a high-pressure charge to prevent the oil from foaming, which maintains consistent damping force during heavy-duty use.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS77042_n523) includes two front shocks to complete the front axle of your vehicle.
