Product Details

KYB Excel-G struts are built on the same OE assembly lines used for original equipment production and use OE-quality components calibrated to restore factory-designed performance rather than change it. Part number 3410073 is a rear suspension strut for 2009-2010 Subaru Impreza models, including the WRX STI application noted by KYB. This part cross-references Subaru 20365FG071 and 20365FG500 for the same application.

The Excel-G line is focused on maintaining ride control, lane-change responsiveness, braking stability, and predictable handling. For Subaru Impreza rear suspension service, 3410073 is a direct-fit replacement option that supports the vehicle’s original suspension behavior.

What It Helps Address

• Excessive bouncing or oscillation from worn rear struts
• Reduced stability during braking and lane changes
• Uneven tire contact caused by weak damping control
• Noisy or loose-feeling rear suspension performance
• Loss of factory ride and handling balance on Subaru Impreza WRX STI models

Installation Notes

Compatible With 2009-2010 Subaru Impreza, rear. KYB notes that the suspension strut and coil spring assembly should be replaced according to the manufacturer’s instructions. For reduced noise and vibration, KYB recommends new strut mounts, part number SM5765. To help protect the new strut from dirt, debris, and salt, KYB recommends a strut boot, part number SB113.

Quality Assurance

KYB is a major OE supplier of shocks and struts, and the Excel-G line is manufactured to OE-quality standards on KYB production lines. The design uses application-specific damping calibration and durable construction intended to restore original suspension performance on the listed Subaru Impreza rear fitments.
