Product Details

Rancho RS5000X shocks are built around an exclusive valving system and advanced compression control to help manage suspension movement on pavement and rough terrain. For Colorado and Canyon owners running a front raised height of 1.0 to 2.5 inches, the RS55375 provides the correct length and mounting style for a direct front shock replacement. This part cross-references Monroe Shocks & Struts 172286 for the same application.

The RS5000X line focuses on controlled damping for daily driving, towing, and trail use, making it a practical choice when you want more stable front-end behavior from your Chevrolet Colorado or GMC Canyon. Part number RS55375 is also referenced as RS5375.

Common Problems It Can Help Address

  • Excessive front-end bounce after bumps
  • Reduced control over rough roads and washboard surfaces
  • Unstable ride feel on lifted front suspensions
  • Worn shock performance from age and mileage
  • Inconsistent damping after suspension height changes

Installation Notes and Tips

Verify front ride height before ordering, since this shock is specified for 1.0 to 2.5 inches of front raised height. It is not for use with aftermarket shock spacers or relocation brackets. Confirm upper stem and lower loop mount dimensions against the vehicle before installation, and inspect surrounding suspension components for wear while the shock is removed.

Quality Assurance

Rancho RS5000X shocks are engineered with application-specific valving and compression tuning for consistent suspension control. RS55375 is built to match the listed fitment and mounting specifications for 2004-2012 Chevrolet Colorado and GMC Canyon front applications.
