Product Description

The Rancho RS55237 is a front shock absorber from the RS5000X Series engineered to improve suspension control and ride comfort on select Ford trucks and SUVs. Its twin-tube internal design combined with progressive engagement valving delivers smoother handling across varied terrain, from daily driving to light off-road trails. The gas-charged construction helps reduce damping fade for consistent performance over long drives.

Built with a nitro-carburized piston rod for strength and corrosion resistance, and durable rubber bushings that reduce vibration and noise, this shock is ideal for refreshing worn or aging front suspension components. Designed as a direct fit for front suspension on Ford F-150, F-250 (light duty), Expedition, and F-150 Heritage 4WD models, it installs using existing mounting points. Rancho RS55237 is a reliable upgrade for drivers seeking enhanced control without a full suspension overhaul.
