Product Details

FCS 342946 is a direct-fit rear shock absorber for 2006, 2007, 2008, 2009, and 2010 Jeep Commander models. The dimensional specs are important for rear suspension geometry, ride height control, and proper suspension movement, especially when replacing a worn shock on a Jeep Commander rear suspension system. FCS brand line parts are positioned as application-specific suspension components, and this unit follows the listed rear fitment for the Commander platform. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems It Can Address

  • Excessive rear bounce after bumps
  • Rear-end instability over uneven pavement
  • Reduced damping from a worn shock absorber
  • Suspension noise caused by a fatigued rear shock
  • Poor rear ride control in a 2006-2010 Jeep Commander

Installation Notes and Tips

Verify rear suspension fitment by matching the vehicle year and position before installation. Compare the compressed length, extended length, and stroke length to the removed unit to confirm proper travel and mounting range for the Jeep Commander rear suspension. Inspect surrounding suspension components for wear before completing the repair.

Quality Assurance

FCS 342946 is cataloged as a suspension shock absorber with defined dimensional specifications for the listed rear application. Use the part number 342946 and the vehicle fitment details to confirm the correct replacement for your Jeep Commander.
