SECTION 7
TWIN CAM CONVERSION CHAIN DRIVEN CAMS
  • 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.
  • NOTE: 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.
    NOTE: 99-01 model motors must use the Andrews rear cam sprocket Drag PART # 0925 - 0147 (SUG. RETAIL $69.95). 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.
