Performance Power Train

For over forty years, Zipper’s Performance Products has been the premier performance resource for professional technicians, performance enthusiasts and racers of the Harley-Davidson® motorcycle. Zipper’s Performance set the pace for the rest of the industry by being the first to develop reliable, pre-engineered Performance Kits for Harley® engines. These Performance Kits dramatically reduce the time and effort required to achieve repeatable results. Plus we manufacture best in class products including Red Shift Cams®. Whether you are considering a quick afternoon upgrade with a Zip Kit, performance cams or can’t wait to open the throttle on Zipper’s Muscle Kit, Zipper’s Performance offers Performance Kits to suit any every performance application.
