Rancho RS7MT Rear Monotube Shock for 2017-2026 Ford F-250/F-350 Super Duty RS77047A

Fits 2017-2026 Ford F-250 and F-350 Super Duty 4WD models.

Designed for precision on-road and off-road handling, the Rancho RS7MT monotube shock is highly effective at dissipating heat, making it an essential upgrade for 2017-2026 Ford Super Duty trucks equipped with larger wheel and tire packages. The high-pressure nitrogen gas charge maintains constant pressure against the hydraulic oil to reduce aeration and shock fade during aggressive use.

The RS7MT features a large 2-inch monotube body filled with all-weather fluid, allowing it to withstand internal temperatures from -40 to 248°F. For maximum durability, it is built with a 14mm hardened chrome piston rod and a 46mm fluon-banded piston that ensures a consistent seal. The integrated dirt wiper sealing system protects the internal seals from moisture and debris, while the internal rebound bumper and shouldered rubber bushings help eliminate ride harshness and vibration.
