Detailed Description

KYB 339072 is designed for the front right suspension on the 2003-2006 Acura MDX. As part of the Excel-G line, it focuses on restoring the vehicle’s original ride control rather than changing the factory driving feel. The nitrogen gas-charged twin-tube design, OE-quality components, and application-specific damping calibration help support stable braking, lane changes, and everyday handling on the Acura MDX.

KYB also builds this strut with a triple-lip fluid seal to help limit leakage and with a rigid body and bracket structure to reduce flex under load. That matters on vehicles with electronic safety systems, since suspension behavior affects how the brakes, tires, and stability systems operate as designed. KYB Excel-G part number 339072 is a practical OE-style replacement for drivers servicing the front right strut on 2003, 2004, 2005, and 2006 Acura MDX models.

What It Can Help Address

• Excessive bounce or poor damping at the front right corner
• Reduced steering response during lane changes
• Uneven body movement over bumps and dips
• Suspension fluid or gas leakage from a worn strut
• Alignment instability caused by flex in a fatigued strut assembly

Installation Notes and Tips

Fits 2003-2006 Acura MDX, front right. 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 KYB OE assembly lines using OE-quality components. This part is calibrated to restore factory-designed performance for the Acura MDX application and is built to support consistent suspension operation in daily driving.
