Product Details

The KYB Excel-G line is engineered to return the suspension to its original operating characteristics rather than change ride feel. Part number 339038 is built on KYB OE assembly lines using OE-quality components and is classified as an Original Equipment for the Aftermarket replacement. This front left strut is a direct match for 2007-2013 Acura MDX, front left, and 2010-2013 Acura ZDX, front left, excluding electronic adjustable or electronic suspension systems. This part cross-references Monroe Shocks & Struts 72434 for the same application.

What This Strut Helps Address

  • Excessive bounce or poor damping at the front left corner
  • Reduced steering response during lane changes and cornering
  • Longer stopping distances caused by unstable suspension control
  • Uneven tire contact from worn or flexing strut components
  • Noise or vibration from aging suspension parts

Installation Notes

Fits 2007-2013 Acura MDX, front left, recommended OEM replacement; excludes electronic adjustable suspension. Fits 2010-2013 Acura ZDX, front left, recommended OEM replacement; excludes electronic suspension. KYB recommends replacing the strut mount, part number SM5212, to reduce noise and vibration, and adding a strut boot, part number SB102, to help protect the strut from dirt, debris, and salt. Verify suspension type and position before installation.

Quality Assurance

KYB is a major OE supplier to new vehicle manufacturers, and the Excel-G line is produced on the same KYB OE assembly lines with OE-quality components. The design focuses on restoring factory-calibrated suspension performance for the Acura MDX and Acura ZDX.
