Heavy gauge steel construction. Most front fenders are available in three different widths (measured inside fender). Fenders are inspected personally by a master fender builder to assure straightness, consistency and a flawless finish with an absolute minimum of finishing bodywork. Fenders come un-drilled (unless noted) so you can position them to look and work best for your application. The predrilled fenders may need spacers. Handmade in the USA.
