Product Line Details

KYB Excel-G is the brand’s original-equipment-style replacement line. It is built on KYB OE assembly lines using OE-quality components and calibrated to restore the vehicle’s designed performance rather than change it. For drivers servicing a Volkswagen Beetle front suspension, part number 343143 is a direct-fit style replacement focused on control and consistency.
