Chain-driven Conversion Camshaft

Allows upgrading the Twin Cam '99-'06 (excluding '06 Dyna Glide) to roller timing chains and replaces spring tensioners with hydraulic tensioners for greater durability.
The listed cam profiles are designed for use with original pushrods; they require the installation of cam plate, oil pump, cam gears and chains and both hydraulic cam chain tensioners from '07-'17 models (these parts are not included and must be purchased separately).
Each cam kit includes a list of required components
Performance should be similar to previous models with the same cam profiles
Manufactured in the USA
Twin Cam '99-'06 engines (except '06 Dyna Glide) cannot use '07-'17 camshafts, as the bearing diameter on earlier engines is .875" and on '07-'17 camshafts is 1.000". The "N" series camshafts have the .875" bearing, but accept the new support plate.
'99-'01 models require an Andrews camshaft sprocket. '02-'06 models must use the original rear sprocket, OEM #25728-06.
The installer must check the spring stop, valve clearance and valve-to-piston clearance.
Direct fit cams with identical performance to original equipment
Slight power increase compared to standard.
No modification to the original system required.
Can be used with original valve springs and tappets.
