Descriptions and notes

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 heattreating 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).

00-06 model cams use a splined cam drive sprocket. These cams will fit in the 1999 Twin Cam motor, but the splined cam drive sprocket OEM #25716-99 or DS-199175 must be used. Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance.
