Product Details

Rancho RS5000X RS55808 is engineered for front suspension service on Ram trucks that retain factory ride height or 0" lift. The RS5000X line focuses on controlled damping through a unique valving system, helping the strut respond consistently during everyday driving, load changes, and uneven road conditions. For Ram 1500 and Ram 1500 Classic owners, this front strut supports a direct replacement path for worn OE-style suspension components while maintaining the intended front suspension geometry.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Front-end bounce or excessive oscillation after bumps
• Reduced steering stability on rough pavement
• Uneven damping response from a worn front strut
• Noisy or inconsistent front suspension movement
• Loss of control feel during daily driving or light off-road use
