Rear cam sprocket w/ ign. trigger ring

The roller chain drive was introduced in 2006 on the Dyna and commonly used from 2007 in all Twin Cam engines to replace the silent chain drive. The conversion kit exchanges the high power spring loaded chain adjuster for an oil pressure based system to maintain chain tension. Also the journal bearing on the sprocket end is replaced with a bigger and sturdier piece. Less wear and easy installation are direct results of these innovations. These conversion kits allow Twin Cam owners enhanced performance and prolonged engine life. You have to order a set cams from the list below, as well as a Roller Chain conversion kit for 1999-2001 Twin Cam or 2002-2006 Twin Cam. These kits include the late style oil pump that is required to let the oil pressure operated cam chain tensioners work properly, as well as all other parts required to install your Andrews Roller Chain Conversion cams. Please note that these conversion cams do not fit 2006-2017 Dyna, nor any other 2007-2017 Twin Cam. These cams are designed for use with stock hydraulic lifters. Matching EZ-install pushrod kits are also available, they are listed elsewhere in this chapter.
