CAM ROLLER CONVER. 21N

Conversion Chain Driven Cam

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.

Bolt-in cams with more torque at low and middle range 1700 - 4800 rpm. Similar to EV23 for heavy bikes. Ideal for heavy bikes with stock compression ratios and stock pistons. Can be used with stock valve springs and tappets.
