Excel-G Product Line Details

KYB Excel-G is built on the same OE assembly lines used for KYB original equipment products and uses OE-quality components. The line is calibrated to return the vehicle to its designed performance rather than change ride characteristics, which is why it is commonly selected for OE replacement service on the Audi A4 and other passenger vehicles.
