KYB 339015 Suspension Strut - Front

KYB Excel-G Front Suspension Strut

The KYB Excel-G 339015 is a front suspension strut built to restore original ride control on select Chevrolet and Pontiac applications. It is a nitrogen gas-charged, twin-tube design made on KYB OE assembly lines with OE-quality components for a direct replacement approach.

For drivers searching for a front strut for a Chevrolet Impala, Chevrolet Monte Carlo, or Pontiac Grand Prix, this KYB Excel-G unit is calibrated to return factory-style handling, steering response, and body control without changing the vehicle’s intended suspension behavior.

Product Details

KYB Excel-G is part of KYB’s OE-focused product line, built for drivers who want original-equipment ride characteristics rather than a modified feel. The 339015 uses a twin-tube, nitrogen gas-charged construction and OE-quality components to support consistent damping performance. It is a practical choice for restoring front suspension response on 1999-2016 Chevrolet Impala, Chevrolet Monte Carlo, and Pontiac Grand Prix applications listed below.

This part cross-references Monroe Shocks & Struts 71661 for the same application.
