ANDREWS Conversion Camshaft - Harley-Davidson '99-'06 - 216821

• Allows you to upgrade your 99-06 Twin Cam (except 06 Dyna Glide) to the newer roller-style cam chains and replaces the spring tension cam chain adjusters with the later-style hydraulic adjusters for longer life
• Cam grinds listed are designed to be used with stock lifters
• They require the installation of a 2007 cam plate, oil pump, cam sprockets and chains, and both hydraulic chain adjusters
• These parts are not included and must be purchased separately
• A list of required components is supplied with each set of cams
• Performance should be similar to earlier bikes with the same cam grinds.

NOTE: 99-06 Twin Cam motors (except 06 Dyna Glide) cannot use the 2007 cams, as the bearing journal on the earlier motors is .875 in. in diameter and the 2007 cams are 1.000 in. in diameter. The "N" series of cams feature the .875 in. bearing journal, yet still accept the new style cam support plate.
NOTE: 99-01 model motors must use the Andrews rear cam sprocket - PART #140050. 2002-2006 models must use the stock rear cam sprocket, OEM # 25728-06.
NOTE: Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance.
