Product Details

Rancho RS5000X RS55315 is a suspension shock absorber engineered for the rear of 2005-2011 Ram and Dodge Dakota models and 2006-2009 Mitsubishi Raider models with 0 inch raised height. The RS5000X line focuses on controlled compression and consistent damping response, helping the vehicle feel more composed during everyday driving and when the road surface becomes uneven. This part cross-references Monroe Shocks & Struts (e.g., 911277) for the same application.

Compatible With 2011 Ram Dakota, rear; 2005-2010 Dodge Dakota, rear; and 2006-2009 Mitsubishi Raider, rear. The Rancho RS55315 is a direct-fit rear shock absorber for these listed applications and is identified by the RS5000X brand line.

What It Helps Address

• Excessive rear-end bounce after bumps
• Loose or unsettled ride feel on rough pavement
• Reduced damping control during load changes
• Worn rear shock performance on higher-mileage trucks
• Inconsistent handling response on mixed road surfaces

Installation Notes

Verify rear suspension configuration and 0 inch raised height before installation. This shock uses loop bushing and sleeve mounts at both ends, with LS28 upper and lower mounting codes. Compare compressed length, extended length, and travel length to the original part before installation on your Dakota or Raider.

Quality Assurance

Rancho RS5000X shocks are built around a specialized valving system and compression control strategy to deliver consistent damping performance for street and light off-road use. The RS55315 is cataloged for the listed vehicle applications and mounting specifications.
