Heavy 14 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. All fenders must be prefitted before painting.
