Product Details

KYB Excel-G is KYB’s OE-style replacement line for drivers who want suspension performance returned to factory specifications rather than changed. For the Subaru Legacy, this front left strut is calibrated to manage tire contact, steering response, and body movement in normal driving conditions. It is also a practical choice when replacing a worn strut on a 2013-2014 Subaru Legacy and restoring consistent ride quality.

This part cross-references Subaru 20310AJ07A for the same application. The KYB 3340107 is commonly selected for Subaru Legacy front left suspension service where original control and handling are the goal.

What It Helps Address

• Excessive bouncing after bumps
• Loose or delayed steering response
• Nose dive during braking
• Uneven tire contact and reduced road control
• Noise or vibration from a worn front strut

Installation Notes

Install according to the manufacturer’s instructions for the 2013-2014 Subaru Legacy front left position. KYB recommends replacing the strut mount, part number SM5361, to reduce noise and vibration, and using a strut boot, part number SB103, to help protect the strut from dirt, debris, and salt. The original coil spring assembly should be handled per factory service procedures.

Quality Assurance

KYB is a major OE supplier, and the Excel-G line is produced on the same assembly lines used for original equipment applications. The design uses OE-quality components and application-specific damping calibration to restore designed suspension performance on the Subaru Legacy.
