About Our Branch-O'Keefe Cams

All Branch-O’Keefe camshafts are custom designed for Twin-Cam applications and utilize gear-drive technology in contrast to the standard Harley Davidson’s chain drive. The main advantage to gear-drive cams is that less effort is needed to spin them, compared with their stock counterparts. Additionally, gear-drive cams do not utilize a tensionser as do chain drive applications, which frees up previously unrealized horsepower from your engine. Removal of the chains and their tensioners will also result in decreased maintenance and reduce the chance of potential engine damage due to tensioner problems. To keep pace, we offer Evo owners a selection of three different designed sizes from Andrews. All of the cams we offer are proudly made in America.
