Product Details

KYB Excel-G shocks and struts are engineered to restore the vehicle’s original suspension behavior rather than alter it. For the Fiat 500L rear shock replacement, part number 3410121 provides the dimensions and mounting style needed for a direct service application. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Shock Absorber Helps Address

• Excessive bouncing after bumps
• Loose or unsettled rear ride control
• Reduced stability during lane changes
• Longer stopping feel caused by worn rear damping
• Uneven handling response from tired suspension components

Installation Notes

Verify rear fitment on the 2014-2020 Fiat 500L before installation. Match the upper and lower mount types, compressed length, extended length, and stroke length to the original part. Inspect related suspension hardware and mounting points for wear, and replace any damaged components as needed during service.

KYB is a global OE supplier of shocks and struts, and the Excel-G line is produced on the same KYB OE assembly lines using OE-quality components. Part number 3410121 is built to restore designed suspension performance for the Fiat 500L rear application.
