Product Details

Part number 334307 is part of KYB’s Excel-G line, an OE-style replacement series focused on returning the suspension to its original control characteristics rather than changing ride feel. For Subaru Impreza rear left service, this strut is designed to support stable braking, lane-change response, and consistent handling by keeping the suspension operating as engineered. This part cross-references Monroe Shocks & Struts 72163 for the same application.

Common Problems This Strut Can Address

• Excessive bouncing after bumps or dips
• Reduced rear suspension control during braking or cornering
• Uneven tire contact caused by worn damping
• Noisy or loose-feeling rear suspension behavior
• Loss of original ride height control and body stability

Installation Notes and Tips

For 2002-2003 Subaru Impreza rear left service, replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends new strut mounts, part number SM5244, to reduce noise and vibration, and a KYB strut boot, part number SB102, to help protect the new strut from dirt, debris, and salt. Verify upper mount thread specification 14X1.50 and confirm compressed length 16.34, extended length 23.82, and stroke length 7.48 before installation.

Quality Assurance

KYB is a major OE supplier, and the Excel-G line is built on the same assembly lines used for original equipment production. The 334307 uses OE-quality components and application-specific damping calibration to support factory-level suspension performance on the Subaru Impreza.
