🔧 This conversion kit lets '99-'06 Twin Cam engines (except '06 Dyna Glide) be upgraded to newer roller-style cam chains and replaces spring-tension cam chain adjusters with later-style hydraulic adjusters for improved longevity.
- Cams are designed for use with stock lifters but require 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.
- Expected performance is similar to earlier bikes fitted with the same cam grinds.
- Made in the United States.
- Note: earlier '99-'06 Twin Cam motors cannot accept the '07-'17 cams because the bearing journal on the earlier motors is .875" in diameter while the '07-'17 cams are 1.000" in diameter; some cams feature the .875" bearing journal yet still accept the new-style cam support plate.
- '99-'01 model motors require the appropriate rear cam sprocket for those years; '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 before riding.
⚙️ A thorough installation and the separately purchased components listed with the cams are required for proper fit and performance.
