VThunder® cams provide the ultimate in arm-stretching, white knuckle power in both street and competitive
Most cam designers concentrate on getting the most power in a particular RPM range and disregard valve train
clatter and power band width. The designers at VThunder® pay particular attention to ramp design to keep our
cams as quiet as possible and lobe design to maintain as wide a power band as possible. VThunder® cams are
made from 6150 aircraft quality steel for ultimate durability and resistance to premature cam failure from metal
fatigue. We heat treat our cams to provide a case depth that allows for long term use under extreme loads.
With the aid of computer controlled machining centers, VThunder® cams are held to extremely
Backed by hundreds of hours on the Dyno and on-bike testing, our power proven cams provide added punch for
all levels of performance needs and riding styles for Evolution® and Shovel engines. Our cams provide the
longevity and valve train integrity you’ve come to expect with Harley Davidson®. Made in the U.S.A. with
American steel, our cams are packaged in full color high-strength boxes complete with detailed installation
instructions. VThunder® by COMP Cams® also offers a one-off special cam grind service.
