Restore the designed ride control, stability, and handling of your Lexus RX with the KYB Excel-G Suspension Strut 339281, a nitrogen gas-charged, twin-tube gas strut for the front-right position. It's a direct-fit replacement for the 2010-2015 Lexus RX350, 2010-2015 Lexus RX450H, and 2010-2013 Toyota Highlander — see the Buyer's Guide tab for engine-level applications.
KYB's Excel-G line is built on the same assembly lines as its OE production and calibrated to return original, designed performance rather than change it — the classification KYB calls OEA (Original Equipment for the Aftermarket).
- Twin-tube gas design: nitrogen gas-charged construction using the same quality components as KYB's global OEM products.
- Triple-lip fluid seal: helps reduce the chance of oil and gas leaking out.
- Rigid strut body and brackets: designed to minimize flex and help maintain correct alignment in all conditions.
- Vehicle-specific damping valves: hand assembled in-house to manage tire contact, steering response, and body movement, helping electronic safety systems perform as designed.
Made in USA. Signs a strut may need replacing include excessive bounce, nose-dive under braking, uneven tire wear, or fluid leaking from the strut body.
