Andrews A2 Camshaft – 1948-1969 Harley-Davidson Big Twin

Whether you want a good street cam for a stock motor, a big cam for a dragster, or something in between, Andrews Products can supply it. All Andrews cams for Shovel and Panhead engines are computer designed and precision ground from alloy steel billets on Landis CNC cam grinders. When purchasing camshafts be sure to make sure they are correct for your model, refer to your manual for cam replacement procedures, and be aware you will need to change intake and exhaust components to achieve maximum results. See below for camshaft specifications, and Additional Information for complete fitment information.
