About the Excel-G Line
KYB Excel-G is an OE-style replacement line built on KYB assembly lines using OE-quality components. For Mazda CX-9 owners, KYB 339140 is engineered to return the suspension to its original control profile rather than change the vehicle’s ride character. This makes KYB 339140 a practical choice when replacing a front right strut on a 2007-2015 Mazda CX-9.

- Suspension performance issues that can interfere with electronic safety systems

Quality Assurance
