330-0459 Easy Start chain drive MR103 camshaft kit (CD)

This S&S Easy Start chain drive MR103 camshaft kit is a fantastic choice for 1999 to 2006 Twin Cam riders, excluding 2006 Dyna models, looking for more power across the 2500 to 5500 RPM range. With a .585-inch lift, these cams work exceptionally well with stock 103-inch engines or those with ported heads. The Easy Start feature uses a spring-loaded lobe to reduce compression during starting, protecting your starter motor and battery. This complete kit comes with the necessary gaskets and bearings. Keep in mind that these are not bolt-in cams; they require high-lift valve springs and may need clearancing in the cam chest. They are not compatible with kickstart models.
