Product Details

The KYB Excel-G line is engineered to return the suspension to its original operating characteristics rather than change ride feel. For the Acura MDX, part number 339073 uses OE-quality components and KYB’s OE assembly-line manufacturing approach to support consistent damping performance. This front left strut is a practical choice when the goal is to restore handling balance, lane-change response, and braking stability on the Acura MDX.

This part cross-references Monroe Shocks & Struts 72230 for the same application.

What It Helps Address

• Excessive bounce or float after bumps
• Reduced steering response during lane changes
• Uneven tire contact caused by worn damping control
• Noise or vibration from a fatigued front strut
• Loss of ride stability on the Acura MDX

Installation Notes and Tips

Fits 2003-2006 Acura MDX, front left. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends new strut mounts, part number SM5211, to reduce noise and vibration. A KYB strut boot, part number SB104, can help protect the strut from dirt, debris, and road salt.

Quality Assurance

KYB is a major OE supplier, and the Excel-G line is produced on the same KYB assembly lines used for original equipment applications. Part number 339073 is built to OE-style standards for restoring factory suspension performance on the Acura MDX.
