Product Details

KYB 3410031 is a rear suspension strut for the Subaru Outback that focuses on restoring factory ride characteristics. It uses OE-quality components and a twin-tube, gas-charged design to support controlled damping over everyday road conditions. The Excel-G product line is built for drivers and technicians who want original suspension behavior, not a changed ride feel. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Suspension Issues It Can Address

• Excessive rear bounce after bumps
• Reduced stability during lane changes and cornering
• Loose or delayed steering response
• Uneven tire contact caused by worn damping control
• Suspension noise or poor ride control from a worn rear strut
