The Rancho RS5000X rear shock for 1999–2016 Ford F-250 Super Duty focuses on improved ride control and durability through Cross Tuned valving and advanced compression phase. Self-lubricating seals and a larger piston area help deliver smooth compression and quicker rebound. Built with a nitro-carburized piston rod, twin-tube body and nitrogen charge, it aims to reduce damping fade and maintain stable shock motion under demanding conditions.
