Product Description

The Rancho RS55286 RS5000X rear shock absorber is engineered to enhance ride quality and improve handling on select full-size trucks and luxury pickups. Designed as a direct bolt-on replacement for worn or factory shocks, this RS5000X unit delivers progressive damping that smooths out rough road impacts and maintains control in varied driving conditions. Its robust twin-tube construction with a nitro-carburized piston rod and protective dust boot bolsters durability for everyday driving and light trail use.

This gas-charged shock features Rancho's tuned valving and compression design to help minimize foaming and shock fade during repeated cycling. Rubber bushings and a rebound bumper reduce noise and vibration for a more comfortable ride, while the reliable performance characteristics make it suitable for both 4WD and 2WD applications where fitment is confirmed. The RS55286 fits a range of Ford F-150 trucks from 2004 through 2013 (4WD for 04-08 and 2WD for 09-13) and Lincoln Mark LT pickups from 2006-2008, offering broad compatibility for stock height rear suspension setups.
