VThunder® cams provide the ultimate in arm-stretching, white knuckle power in both street and competitive applications.
rn
rn 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. rn rn VThunder® cams are made from 6150 aircraft quality steel for ultimate durability and resistance to premature cam failure from metalrn 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 precise tolerances.rn rn rn
