ANDREWS Conversion Camshaft 216837

Allow 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 07-17 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, Made in the U.S.A., 99-06 Twin Cam motors (except 06 Dyna Glide) cannot use the 07-17 cams, as the bearing journal on the earlier motors is .875″ in diameter and the 07-17 cams are 1.000″ in diameter. The “N” series of cams feature the .875″ bearing journal, yet still accept the new style cam support plate, 99-01 model motors must use the Andrews rear cam sprocket Drag part #0925-0147. 2002-2006 models must use the stock rear cam sprocket, OEM #25728-06, Installer must check coil bind, valve-to-valve clearance and valve-to-piston clearance
