Product Description

The **Rancho RS55046** RS5000X™ rear shock absorber is engineered to elevate ride quality and suspension control for **2005-2016 Ford F-250 and F-350 Super Duty trucks** in both 4WD and RWD configurations. Featuring Rancho's Progressive Engagement valving and tuned compression control, this gas-pressurized shock delivers smoother handling over rough terrain and everyday driving conditions. Its twin-tube design with a large 2.25" body increases fluid capacity to help reduce heat-related performance fade and maintain consistent damping.

Constructed with a 16 mm nitro-carburized piston rod to resist corrosion and wear, the RS55046 includes a protective red boot and reliable rubber bushings that help absorb harsh road inputs. Installation uses standard eyelet-to-eyelet mounting points, making it a direct substitute for stock rear shocks. Backed by Rancho's limited lifetime warranty, this RS5000X shock is ideal for owners seeking improved ride performance and durability for their Super Duty rear suspension.
