Feuling HP+ 405 Camchest Kit For Harley Water Cooled M8

This kit includes everything you'll need to put some pep in your M8 motor. The Reaper 405 camshaft works seamlessly with the included high volume oil pump, camplate, lifters, heavy duty pushrods and more.

The 405 Reaper is a workhorse, producing a wide powerband, increasing torque and HP throughout the entire RPM range when compared to stock.  Will respond well with slip-on mufflers and or complete exhaust system and a high flow air cleaner. Note Feuling recommends using free flowing mufflers with smaller cores for best lower RPM power and pull. RPM range 1700-5700.
