The right cam choice can make the difference between a bike that chugs or a bike that's a slug! V Thunder cams provide the ultimate in arm-stretching, white knuckle power in both street and competitive applications. Most cam designers concentrate on getting the most power in a particular rpm range and disregard valve train clatter and power band width. At V Thunder, designers pay particular attention to ramp design to keep these cams as quiet as possible and lobe design to maintain as wide a power band as possible. Made from 6150 aircraft quality American steel for best longevity and resistance to early cam failure from metal fatigue. Heat treated to provide a case depth that allows for long term use under the severest of loads. Held to extremely precise tolerances with CNC machining. Backed by hundreds of hours on the dyno and on-bike testing. U.S.A. Made. Includes detailed instructions.
