Product Details

KYB Excel-G is the brand’s OE replacement line for drivers who want the suspension to perform as the vehicle manufacturer originally calibrated it. This KYB strut, part number 339854, is made on KYB OE assembly lines with OE-quality components and is classified as an Original Equipment for the Aftermarket (OEA) part. For a Fiat 500 front right strut replacement, it is built to restore ride control, lane-change responsiveness, and braking stability without changing the vehicle’s intended suspension behavior.

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

What It Helps Address

• Excessive bouncing or unsettled ride quality
• Reduced steering precision during lane changes and cornering
• Front-end dive, sway, or body movement over uneven roads
• Suspension fluid or gas leakage from a worn strut
• Alignment instability caused by flex in a worn strut body

Installation Notes

Fits 2012-2017 Fiat 500, front right. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends installing new strut mounts, part number SM5685, to reduce noise and vibration. A KYB strut boot, part number SB101, can help protect the new strut from dirt, debris, and road salt.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers worldwide, and the Excel-G line is built on the same OE assembly lines using OE-quality components. That manufacturing approach supports consistent fitment and restoration of original suspension performance for the Fiat 500 application.
