Let's face it, nothing grabs our attention at a car show or cruise night more than the hard hitting sound a thumping, high performance idle. Thumpr™ Camshafts deliver that aggressive, head-turning sound like no other cam on the market. Available in hydraulic flat tappet and hydraulic roller camshafts, Thumpr™ Cams are now available for most popular applications, carb and late model efi.

Designed to provide maximum performance when combined with the latest in valve train components, such as Beehive™ Valve Springs, Ultra Pro Magnum™ Rockers and Magnum™ Pushrods
