Rancho® RS7MT® Struts Deliver Precision Performance

Rancho® RS7MT® Struts Deliver Precision Performance

Importance of Struts

Designed to help with your vehicle’s ride and handling, struts are a major structural component of the suspension system. Along with shocks, struts keep your vehicle’s tires in contact with the road which helps:

  • Control excessive tire and body movement
  • Reduce vehicle sway, roll and bounce
  • Helps maintain wheel alignment and consistent handling and braking
  • Cuts down on premature wear on other suspension parts and tires

In addition, struts perform two unique functions. Like a shock, struts aid in damping but unlike shocks, struts perform a support function holding the tire in an aligned position and bracing the spring.

Advantages of a Rancho® RS7MT® Strut

Application tuned for precision on-road and off-road handling, Rancho RS7MT monotube struts are highly effective in the dissipation of heat, making them ideal for extreme off-road use and larger wheel and tire packages. RS7MT struts feature an integrated dirt wiper sealing system that keeps dirt and debris out, hardened piston rod that resists scuffs and corrosion plus an internal rebound bumper to smooth out your ride on any terrain.

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.

STRONG AND DURABLE - 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

REDUCES FADE - Full-floating dividing piston and high-pressure nitrogen gas maintains constant pressure against the hydraulic oil, reducing aeration and fade

SMOOTH PERFORMANCE - 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

THE RIGHT FIT - Designed to fit right out of the box, application-specific mounting installs easily with no need for installing sleeves or extra hardware

KEEPS DIRT AND DEBRIS OUT - Sealing system with integrated dirt wiper helps keep moisture, dirt and debris from being ingested into the strut and contaminating the oil and destroying the internal seal

BUILT TO LAST - Large 46mm fluon-banded piston for consistent sealing between the piston and monotube for precise control, ride and handling

BOLD APPEARANCE - Black satin finish with distinctive Rancho red logo for an eye-catching look that stands out

BUY WITH CONFIDENCE - Comes with Rancho’s Limited Lifetime Warranty
