Product Details

KYB Excel-G is the brand’s OE-style product line focused on restoring the vehicle’s original suspension behavior rather than changing it. For a Mazda 6 front left strut replacement, 3350107 is engineered to match factory calibration and maintain the ride control, lane-change responsiveness, and stability expected from the original suspension setup. This part cross-references Monroe Shocks & Struts (e.g., GBFN34900C) for the same application.

Common Symptoms This Part Can Address

• Excessive bouncing or poor damping over bumps
• Reduced steering response during lane changes
• Nose dive under braking
• Uneven ride control on the front left corner
• Loss of stability from a worn suspension strut

Installation Notes

Fits 2018-2021 Mazda 6, front left. Verify the upper mount thread specification of 12x1.25 and confirm the compressed and extended lengths match the original strut before installation. Because this is a suspension strut, professional installation and a wheel alignment are recommended after replacement.

Quality Assurance

KYB is a major OE supplier, and Excel-G is produced on the same KYB assembly lines with OE-quality components to restore original designed performance. The internal rebound spring and nitrogen gas-charged twin-tube construction are part of the OE-style design approach used for this application. Part number 3350107 is built for consistent fitment on the specified Mazda 6 models.
