Precise Handling & Performance: Deflective Disc Valving features digressive, linear or progressive tuning based on application requirements for precision handling and performance on and off-road Reduces Fade: Full-floating dividing piston and high-pressure nitrogen gas maintains constant pressure against the hydraulic oil, reducing aeration and shock fade Built to Last: The large 46mm fluon-banded piston for consistent sealing between the piston and monotube for precise control, ride and handling Buy with Confidence: Knowing that Rancho RS7MT series shocks are backed by Rancho’s limited lifetime warranty, you can purchase this set with confidence Vehicle Compatibility: These Rancho RS7MT shocks are designed to fit 2008-2016 F450 Super Duty Crew Cab with 0” lift Enhance your driving dynamics with Rancho RS7MT monotube shocks! Rancho's Deflective Disc Valving offers precision handling and performance on-and off-road through its digressive, linear or progressive turning capabilities tailored to application requirements. The shock features a 14-millimeter hardened chrome piston rod to resist scuffs and corrosion, double-welded loops at stress areas, and a double-strength closure method. The large 2-inch monotube body is filled with all-weather fluid, allowing for cooler operation, increased vehicle control, and the ability to withstand internal temperatures from -40 to 248 degrees Fahrenheit. A full-floating dividing piston and high-pressure nitrogen gas maintain constant pressure against the hydraulic oil, reducing aeration and shock fade. The internal rebound bumper and shouldered rubber bushings help minimize noise, vibration, and ride harshness, while the PTFE-banded piston enhances responsiveness to changing road conditions for an overall smoother ride. Designed for easy, application-specific mounting with no need for extra hardware, the sealing system with integrated dirt wiper keeps moisture, dirt, and debris from contaminating the oil and destroying the internal seal. The large 46-millimeter fluon-banded piston provides consistent sealing between the piston and monotube for precise control, ride, and handling. Finished in a distinctive black satin with the Rancho red logo, this shock is backed by Rancho's limited lifetime warranty. - Vehicle Compatibility: Fits 2008-2016 F450 Super Duty Crew Cab with 0” lift.
