CAM ROLLER CONVER. 21N

Conversion Chain Driven Cam

Upgrades '99–'06 Twin Cam (except '06 Dyna) to late-style roller chains and hydraulic tensioners

Engineered for use with stock lifters; requires '07-'17 cam plate, oil pump, sprockets, chains, and hydraulic adjusters (sold separately)

Performance output matches original Andrews profiles built for same-generation grinds

Made in the USA

'99-'06 Twin Cam motors (except '06 Dyna) cannot use standard '07-'17 cams due to journal size split. Standard late-model cams feature a 1.000" diameter, while earlier motors require the 0.875" outer bearing journal engineered into this "N" series.

'99-'01 model motors require Andrews rear cam sprocket . '02-'06 models must reuse the stock factory 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.
