Upgrade your '99-'06 Twin Cam (excluding '06 Dyna Glide) engine with the Andrews Conversion Chain Driven Cam. This kit allows you to convert to newer roller-style cam chains and replaces the spring tension cam chain adjusters with late-model hydraulic adjusters, offering enhanced durability and performance. Experience improved reliability and smoother operation with this comprehensive upgrade solution. Description The Andrews Conversion Chain Driven Cam allows you to bring modern cam chain technology to your earlier Twin Cam engine. Designed for use with stock lifters, these cam grinds deliver performance comparable to earlier bikes equipped with similar cams. By upgrading to the '07-'17 cam plate, oil pump, cam sprockets, chains, and hydraulic chain adjusters (available separately), you'll benefit from the improved design and reliability of newer Twin Cam models. This kit ensures optimal valve train performance and longevity, allowing you to ride with confidence. The "N" series cams retain the .875" bearing journal required for '99-'06 models while still being compatible with the new style cam support plate. Always verify coil bind and valve-to-piston clearance during installation. Features & highlights Upgrades '99-'06 Twin Cam engines (except '06 Dyna Glide) to modern roller-style cam chains.
