KYB Suspension Strut P/N:5640009
Help restore the designed control and handling of the front-left corner with the KYB Excel-G Suspension Strut 340039, a nitrogen gas-charged, twin-tube strut that drops in as a direct-fit replacement for the front-left position on the 2010-2012 Ford Fusion, 2010-2012 Lincoln MKZ, and 2010-2011 Mercury Milan. Built on KYB's OE assembly lines from OE-quality components, the Excel-G is calibrated to restore original, designed performance rather than change it — the classification KYB calls OEA (Original Equipment for the Aftermarket).
KYB recommends installing new strut mounts (part number SM5540) to reduce the chance of noise and vibration, and protecting your new struts from dirt, debris, and salt with a KYB Strut Boot (part number SB101).
