Product description
Upgrade your 1999-2006 Twin Cam motorcycle (excluding the 2006 Dyna Glide) with our advanced cam system designed to enhance performance and longevity. This kit allows you to transition to the newer roller-style cam chains and replaces the traditional spring tension cam chain adjusters with modern hydraulic adjusters, ensuring a longer lifespan for your engine components.
The cam grinds included in this set are specifically engineered for use with stock lifters and are compatible with the installation of a 2007-2017 cam plate, oil pump, cam sprockets, chains, and hydraulic chain adjusters (note: these additional components must be purchased separately). Each set comes with a comprehensive list of required parts to facilitate your upgrade.
Performance is optimized for heavy bikes, providing increased torque in the low to mid RPM range (1700-4800 RPM), similar to the EV23 profile, making it ideal for those with stock compression ratios and pistons. The system is designed to work seamlessly with stock valve springs and tappets.
Please note that the 1999-2006 Twin Cam motors cannot utilize the 2007-2017 cams due to differences in bearing journal sizes; however, our "N" series of cams feature the .875" bearing journal while still accommodating the new style cam support plate. For 1999-2001 models, the Andrews rear cam sprocket (Drag part #0925-0147) is required, while 2002-2006 models must use the stock rear cam sprocket (OEM #25728-06).
As with any installation, it is crucial for the installer to check coil bind, valve-to-valve clearance, and valve-to-piston clearance to ensure optimal performance and safety. Proudly made in the USA, this upgrade is a reliable choice for enhancing your motorcycle's capabilities.
