KYB 339225 Suspension Strut - Front Left

KYB Excel-G Front Left Strut for Subaru Outback

The KYB Excel-G suspension strut, part number 339225, is built to restore original ride control, stability, stopping response, lane-change behavior, and handling. It is a direct-fit OE-style replacement for the front left position on select Subaru Outback models.

Built on KYB OE assembly lines, the Excel-G line uses OE-quality components and a nitrogen gas-charged, twin-tube design calibrated to return the vehicle to its original designed performance. For Subaru Outback owners looking for a front left suspension strut replacement, 339225 is engineered around factory control characteristics rather than changing the ride feel.

Detailed Description

KYB Excel-G part number 339225 is an OE-style suspension strut for the front left side of the 2010-2012 Subaru Outback. The Excel-G product line is designed to return the vehicle to its original suspension behavior, using KYB’s OE manufacturing approach and calibrated damping to preserve factory ride control. This makes it a practical choice when replacing a worn strut on a Subaru Outback and maintaining the vehicle’s intended steering feel and body control.

This part cross-references Monroe Shocks & Struts (e.g., 72687) for the same application.

What This Strut Helps Address

• Excessive bouncing or oscillation after bumps
• Reduced steering response during lane changes
• Uneven tire contact caused by worn damping control
• Body movement or nose dive during braking
• Noise or fluid loss associated with a worn front strut

Installation Notes and Tips

Install on the front left position only for the listed Subaru Outback applications. Follow the manufacturer’s instructions and replace the suspension strut and coil spring assembly as specified. Verify the upper mount thread size is 12x1.25 before installation. KYB recommends protecting the new strut with a KYB strut boot, part number SB103, to help shield it 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. The design uses OE-quality components and factory-calibrated damping to support consistent suspension performance on the Subaru Outback.
