- Andrews Products grinds its cams using a computer with cam design capabilities. This superior technology gives the utmost in both performance and reliability. Only the best alloy steel billets and heat-treating processes are used. The power in a Harley Twin Cam engine is completely released only when superior Andrews computer-designed high-performance cams are installed. Cams come with new bearings (1 roller and 1 ball). Andrews recommends using their steel cam drive sprocket DS-199175 and crankshaft cam drive sprocket DS-199074 (must be purchased separately)
