Restore the designed ride control, stability and handling of your 2012-2017 Fiat 500 with the KYB Excel-G Suspension Strut 339855, a nitrogen gas-charged, twin-tube strut for the front left position. KYB is a world-leading OE shock and strut supplier, and the Excel-G is built on the very same KYB OE assembly lines using the same OE-quality components, calibrated to restore the vehicle's original, designed performance rather than change it — earning its OEA (Original Equipment for the Aftermarket) classification. It is KYB's recommended OEM replacement strut and a preferred choice among professional technicians.
- Triple-lip fluid seal: helps reduce the chance of oil and gas leaking out.
- Vehicle-specific, hand-assembled damping valves: correctly manage tire contact, steering response and body movement.
- Strong, thick strut body and brackets: minimize flex to help maintain correct alignment in all conditions.
- Supports electronic safety systems: helps keep them performing as designed, since they depend on the suspension, brakes and tires operating as the manufacturer intended.
To reduce the chance of noise and vibration, KYB recommends installing new strut mounts (part number SM5685) and protecting the strut with a KYB Strut Boot (part number SB101). This listing is for one front left strut; replacing both front struts together as a matched pair is recommended for balanced ride and handling.
