TWIN CAM CONVERSION CHAIN DRIVEN CAM 12N

• 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

Bolt-in cams with the same output as the stock cams
Slight power increase when compared to stock
No returning of the stock system is necessary
Can be used with stock valve springs and tappets
