Product Details

KYB Excel-G 339170 is engineered as an Original Equipment for the Aftermarket replacement for Asian SUVs and crossovers. It is designed to restore the Subaru Forester’s original suspension behavior rather than change ride height or handling balance. The strut uses OE-quality construction and calibrated damping to support consistent control during braking, lane changes, and everyday driving. This part cross-references Monroe Shocks & Struts 72679 for the same application.

What It Helps Address

• Excessive front-end bounce or oscillation
• Reduced steering response during turns or lane changes
• Uneven tire contact caused by worn damping control
• Brake dive and unstable stopping feel
• Suspension noise or handling looseness from a worn front left strut

Installation Notes

Compatible with 2009-2010 Subaru Forester front left applications listed above. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify upper mount type 14X1.50 and confirm all suspension components are inspected before installation. Part number 339170 should be matched to the vehicle’s exact application before service.

Quality Assurance

KYB is a major OE supplier, and the Excel-G line is built using OE-quality components on KYB production lines. The design focus is restoring factory ride control and maintaining proper suspension performance for vehicles equipped with electronic safety systems that depend on suspension, brakes, and tires working as intended.
