Product Details

KYB Excel-G struts are engineered as Original Equipment for the Aftermarket (OEA) replacements, using the same manufacturing approach and quality standards associated with KYB OE supply. For the Subaru Outback, this front left strut is calibrated to restore the vehicle’s designed ride control rather than alter suspension behavior. The result is consistent damping for everyday driving, lane changes, braking stability, and body motion control. Part number 3340133 is also referenced for Subaru OE number 20310AL04A.

This part cross-references Monroe Shocks & Struts 172286 for the same application.

Common Symptoms This Strut May Address

• Excessive bouncing after bumps
• Loose or unsettled front-end handling
• Reduced braking stability from worn suspension damping
• Uneven tire contact caused by weak strut control
• Noisy or inconsistent ride quality from a worn front left strut

Installation Notes and Tips

Fits 2015-2017 Subaru Outback, front left. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions.
