Steel fender is thick enough to add rigidity to the front end by acting like a fork brace, but can still be cut or shaped enough for an even more Kustom appearance. Fenders come pre-drilled and are stamped, not spun, to ensure a consistent finish and minimize body work. E-coated to prevent rust and corrosion. Made in the USA. Installation requires the use of Klock Werks Tire Hugger mounting blocks (sold separately)..
