From the pavement to the trail, the new Rancho® RS7MT™ monotube shocks are made for adventure. A complete performance upgrade for your truck’s suspension system, Bring It with RS7MT shocks. Engineered to help you handle anything that comes your way, the RS7MT shocks are application-tuned for precision on-road and off-road handling.
MONOTUBE DESIGN
Highly effective in the dissipation of heat, RS7MT shocks are ideal for off-road use, and larger wheel and tire packages. Featuring an integrated dirt wiper sealing system that keeps dirt and debris out, the RS7MT has a hardened piston rod that resists scuffs and corrosion plus an internal rebound bumper to smooth out your ride on any terrain. In addition, the RS7MT reduces fade and provides responsive damping for a better ride on- and off-road.
PRECISE HANDLING AND PERFORMANCE
Deflective Disc Valving features digressive, linear or progressive turning based on application requirements for precision handling and performance on- and off-road
Features a 14mm hardened chrome piston rod to resist scuffs and corrosion, double-welded loops at stress areas, double-strength closure method, and hot form reserve tube
HANDLES EXTREME TEMPERATURE CHANGES
Large 2-in. monotube body filled with all-weather fluid allows for cooler operation, increased vehicle control, and ability to withstand internal temperatures of -40 to 248°F
Full-floating dividing piston and high-pressure nitrogen gas maintains constant pressure against the hydraulic oil, reducing aeration and shock fade
Internal rebound bumper and shouldered rubber bushings help reduce noise, vibration and ride harshness, while the PTFE-banded piston enhances responsiveness to changing road conditions for an overall smoother ride
Designed to fit right out of the box, application-specific mounting installs easily with no need for installing sleeves or extra hardware
Sealing system with integrated dirt wiper helps keep moisture, dirt and debris from being ingested into the shock and contaminating the oil and destroying the internal seal
Large 46mm fluon-banded piston for consistent sealing between the piston and monotube for precise control, ride and handling; for extra protection, shock boot RS1952 and RS1961 are available for purchase
Black satin finish with distinctive Rancho red logo for an eye-catching look that stands out
