Allows upgrade of the ''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 USA
''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 require Andrews rear cam sprocket . ''02-''06 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.
