Product Description

The **RS55048 RS5000X™ Rear Shock Absorber** is engineered for lifted **2005-2016 Ford Super Duty 4WD** trucks, providing improved rear suspension control and ride comfort over rough terrain and uneven surfaces. With Rancho's Progressive Engagement valving and tuned compression design, this gas-charged shock helps absorb harsh bumps while maintaining stability for lifted rear suspension setups.

Built with a large 2.25" twin-tube body and a nitro-carburized piston rod, the RS55048 resists corrosion and delivers consistent damping performance. Rubber bushings and a protective boot help shield critical components from debris and wear. Designed as a direct replacement for rear shocks on select lifted F-250 and F-350 Super Duty trucks, this shock is ideal for owners seeking enhanced rear suspension performance and comfort. Sold individually, it's recommended to replace in pairs for balanced suspension behavior.
