Product Description

The Rancho RS55185 RS5000X rear shock absorber is a direct-fit performance replacement designed to improve ride quality and handling on select older SUVs and trucks. Built with Rancho's RS5000X gas-charged twin-tube design and progressive engagement valving, this shock delivers smoother damping action over bumps and rough road surfaces compared to many stock replacements. The robust 35 mm piston and nitro-carburized rod enhance durability while the protective boot helps keep contaminants away from the seals.

This shock fits the rear suspension of 1991-2001 Ford Explorer, 2001-2005 Ford Explorer Sport Trac, 1997-2001 Mercury Mountaineer, and 1991-1994 Mazda Navajo vehicles. It's engineered for both daily driving comfort and improved responsiveness during light trail or uneven surface use. As with all RS5000X shocks, Rancho provides a limited lifetime warranty for added confidence.
