330-0016 Chain drive 509 camshaft kit

This S&S 509 chain drive camshaft kit is the ideal solution for 1999 to 2006 Twin Cam owners looking for better low-to-mid range grunt without a complicated installation. It fits all models in that era except for the 2006 Dyna. The 509 grind is designed to pull hard from idle all the way through the mid-range, making it a great choice for heavy cruisers and touring rigs. This is a complete kit that includes two chain-driven cams along with a comprehensive installation package featuring a gear cover gasket, cam bearings, retaining ring, o-ring, and thread locker. Note that 1999 models will require the separate purchase of a 2000-up style splined driven gear to complete the install.
