Rancho RS7MT Shock Absorber for On- and Off-Road Control

The Rancho RS7MT monotube shock absorber is application tuned for precise handling on pavement and consistent control on rough terrain. Built for vehicles with larger wheel and tire packages and demanding off-road use, the RS77113 focuses on heat dissipation, dirt exclusion, and ride stability.

For drivers servicing classic trucks, vans, and 4x4s such as the Jeep CJ7, Ford Bronco, and Nissan Frontier, this shock is built around real-world suspension demands. The RS77113 is part of the Rancho RS7MT line, a monotube shock series aimed at maintaining consistent damping performance across mixed driving conditions.

• Reserve tube diameter: 1.97 in.; body length: 12.91 in.

Detailed Description

Rancho RS7MT shocks are built for drivers who want controlled response on-road and dependable damping off-road. The monotube design helps move heat away from the working components, which supports consistent operation during extended trail use, towing, or driving with larger tires. The RS77113 also uses an internal rebound bumper to reduce harsh extension and improve ride feel across broken pavement, washboard roads, and uneven terrain.

This part cross-references Monroe Shocks & Struts (e.g., 33233970) for the same application. Search terms commonly used for this shock include Rancho RS77113 rear shock absorber, RS7MT shock for Jeep Wrangler rear, and Rancho shock absorber for Nissan Frontier rear.

What It Helps Address

• Excessive bounce after bumps or dips
• Reduced control on rough roads and trails
• Heat-related damping fade during extended use
• Dirt and debris intrusion around the shock shaft
• Ride harshness from larger wheel and tire packages

Installation Notes and Fitment

Install position varies by vehicle. Fits 1998-2004 Nissan Frontier, rear; 1995-2003 Dodge Ram 1500 Van, rear; 1987-1995 Jeep Wrangler, rear with rear raised height 0 in. to 1.5 in. and aftermarket shock adapter bracket; 1982-1986 Jeep CJ7, front with front raised height 0 in. to 2.5 in.; and 1967-1979 Ford Bronco, rear with rear raised height 0 in. Some applications note tighter bushing fitment and extra installation effort, and certain vehicles may require washers or axle shim kits for clearance. Verify raised height, mounting style, and axle clearance before installation.

Additional fitment examples include Fits 1981-1986 Chevrolet K10, front inner; Fits 1976-1986 Jeep CJ7, rear; Fits 1964-1984 Toyota Land Cruiser, front; and Fits 1961-1965 Ford F-100, rear.
