The short overall length gives these an aggressive performance look. Extra wide design with notched (cut-out) sides to fit extra wide 180mm tires on a 5.50x18 rim. Offers bolt-on installation ease without modifications with stock smooth slider covers (fork boots). Fender is made from a single piece of 14-gauge steel. Note: These fat fenders are compatible with Arlen Ness ''fork boots for fat fenders and wheels''; found in our ''suspension'' chapter. These fork boots have a cut-out section which makes them also bolt-on in combination with these wide fenders.
