CAMS FOR TWIN CAM

Andrews Products grinds its cams with the help of 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 utilized. Furthermore, the power in Harley's Twin Cam engine can be made even more convincing when superior Andrews computer-designed high-performance cams are installed.

NOTE: All Andrews gear-driven cams require four-gear set for installation (DS-199532 for 99-06 applications; 0925-0166 or 0925-0152 for 07-17 Twin Cam and 06 Dyna applications).

NOTE: Chain Driven Cams: 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.

NOTE: Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance.

NOTE: 59G, 60G and 64G cams are for highly tuned engines and require the knowledge of an expert engine builder for proper setup and installation.
