Product Description

The **Rancho RS55043 RS5000X™ Front Shock Absorber** is a performance gas-charged shock designed specifically for lifted **2005-2023 Ford F-250 and F-350 Super Duty 4WD** trucks with a typical **2.5" front lift** setup. Featuring Rancho's Progressive Engagement valving and an advanced compression control design, this shock helps deliver smoother ride dynamics over rough terrain and enhances steering control. Its twin-tube construction with a 2.25" body and all-weather fluid works to reduce shock fade and maintain consistent damping performance across varied driving conditions.

Built with a nitro-carburized piston rod and protective red boot, the RS55043 resists corrosion and shields key components from debris. Rubber bushings help absorb harsh ride inputs, and the larger piston design improves structural strength for both off-road and on-road durability. This front shock is a direct replacement for select Super Duty trucks fitted with lifted suspension setups, providing balanced comfort, handling, and control. Rancho's limited lifetime warranty adds peace of mind for long-term use.
