Product Description

The Rancho RS55234 is a performance-oriented rear shock absorber from the RS5000X Series engineered to improve ride control and handling on select late-1990s and early-2000s Ford trucks. Its twin-tube internal design and Progressive Engagement Valving deliver smoother, more controlled suspension movement over varied road surfaces. The nitrogen gas charge helps reduce damping fade for consistent performance across long highway drives or off-road terrain.

Constructed with a nitro-carburized piston rod for strength and corrosion resistance, and durable rubber bushings to reduce vibration and noise, the RS55234 offers long-lasting performance. This rear shock is designed as a direct replacement for worn OEM parts on Ford F-100 Ranger, F-150, and F-150 Heritage models, using existing mounting points for a straightforward installation. It's an ideal choice for truck owners looking to restore ride quality or enhance rear suspension performance without installing a full lift kit.
