Restore the designed control and handling of your Hyundai Tucson or Kia Sportage with the KYB Excel-G Suspension Strut 339403, a nitrogen gas-charged, twin-tube strut for the front left position. It drops in as a direct-fit replacement for the 2010-2015 Hyundai Tucson and 2011-2016 Kia Sportage — see the Buyer's Guide tab for engine-level applications. Excel-G is built on the same KYB OE assembly lines with the same OE-quality components and is calibrated to restore original performance, earning it KYB's OEA (Original Equipment for the Aftermarket) classification.
- Triple-lip fluid seal: reduces 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.
- 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 by keeping suspension response intact.
KYB recommends installing new strut mounts (part number SM5758) and protecting the strut with a KYB Strut Boot (part number SB116) to reduce the chance of noise and vibration. Excel-G is the #1 recommended Original Equipment replacement choice for Asian SUVs and Crossovers.
