Product Details

KYB Excel-G 339150 is engineered for drivers who want the suspension to perform as the manufacturer intended. On the Subaru Forester, the rear left strut plays a direct role in ride comfort, braking stability, lane-change response, and overall chassis control. KYB calibrates the Excel-G line to restore those original characteristics rather than alter them, making it a practical replacement for worn rear suspension components.

This part cross-references Monroe Shocks & Struts 72446 for the same application. It also cross-references Subaru 20360SA190 for the same application.

Common Problems This Strut Can Address

• Excessive bouncing or poor rebound control
• Rear-end instability during braking or cornering
• Uneven tire contact caused by worn damping performance
• Noisy or loose-feeling rear suspension behavior
• Reduced handling precision on a 2006-2008 Subaru Forester

Installation Notes and Tips

Verify that your vehicle is a 2006-2008 Subaru Forester without self-leveling rear suspension before ordering. This strut is for the rear left position only, and the upper mount uses a 14x1.50 specification. Confirm compressed length, extended length, and stroke length against the original part during service. Professional installation and a post-repair alignment are recommended after suspension replacement.

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 design uses OE-quality components and application-specific damping calibration to help keep suspension, braking, and electronic safety systems operating as the vehicle manufacturer intended.
