This pedal bolts right up to most stock Harley big twin frames from 1936-85. Steel construction with brilliant chrome plating. Two lever positions for a stiffer or lighter throw. Unlike a lee or bates pedal these pedals have replaceable brass bushings so your pedal can run smooth for generations. These pedals also have a pedal stop so you don't get that floppy loose pedal like you do with other pedals.
