Product Details

KYB Excel-G is an Original Equipment for the Aftermarket replacement line built on KYB OE assembly lines using OE-quality components. This 334359 strut is engineered for Subaru Impreza rear suspension service where restoring ride control, stability, braking feel, lane-change response, and handling matters.

The upper mount type is 14X1.50, and the unit includes an R-stop design. KYB also notes that new strut mounts, part number SM5422, are recommended to reduce noise and vibration.

What This Strut Helps Address

• Excessive bouncing or poor damping at the rear of the vehicle
• Loose or unstable handling during turns and lane changes
• Reduced tire contact and uneven road control
• Suspension noise caused by a worn rear strut assembly
• Alignment drift from flex in a fatigued strut body

Installation Notes

For best results, inspect related suspension components during service and consider replacing the strut mount if wear is present. This part number is 334359.
