Bring back the ride control, stability, and handling engineered into your BMW with the KYB Excel-G Suspension Strut 339787. This nitrogen gas-charged, twin-tube front strut is a direct-fit replacement for the 2007-2013 BMW X5 and 2008-2014 BMW X6 — see the Buyer's Guide tab for the full engine-level applications. Built on KYB's OE assembly lines using OE-quality components, the Excel-G is calibrated to restore the vehicle's original, designed performance rather than change it, earning its OEA (Original Equipment for the Aftermarket) classification.
- Triple-lip fluid seal: designed to reduce the chance of oil and gas leaking out.
- Vehicle-specific damping valves: hand-assembled in-house to manage tire contact, steering response, and body movement.
- Heavy strut bodies and brackets: among the strongest and thickest in the industry, minimizing flex to help maintain correct alignment.
- Twin-tube, gas-charged design: the KYB-recommended OEM replacement strut, and a preferred choice among professional technicians.
Because it helps keep the suspension, brakes, and tires operating as the manufacturer intended, the Excel-G also helps electronic safety systems perform as designed. If worn front struts are the cause of poor ride control or handling, this unit replaces them.
