Conversion Chain Driven Cam Harley Davidson FLHR 1450 1999 2003

Features: 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 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..
