Product Details

Excel-G is KYB’s OE-style product line for drivers who want factory-correct suspension behavior rather than a changed ride character. This KYB 335037 front strut is made on KYB OE assembly lines using OE-quality components and is calibrated to return the vehicle’s original control characteristics. It is a direct-fit suspension strut for front applications on 2000-2005 Buick LeSabre, 2000-2005 Cadillac DeVille, 2000-2005 Pontiac Bonneville, and 2001-2003 Oldsmobile Aurora. This part cross-references Monroe Shocks & Struts 71685 for the same application.
