Camshaft Kit for Twin Cam
Andrews TC Cam Upgrade Kit for converting all 1999-06 Twin Cam Big Twin to the 2006-17 roller chain drive with hydraulic chain tensioners. Instead of super pow-
ered spring adjusters the roller cam chain adjuster uses engine oil pressure to maintain proper chain tension and roller chain camshafts have larger journal bearing for
extra support on the sprocket shaft ends. Kit includes cams only and requires separate purchase of 2007-17 oil pump, support plate, chain tensioners sprockets and
hardware. See camshaft components page for additional parts required to complete conversion. Note: For 1999, 2000 and 2001 engines a rear cam drive sprocket
with an ignition trigger ring must be used.
