COMP Cams Mutha Thumpr Hydraulic Roller Camshafts

COMP Cams Mutha Thumpr hydraulic roller camshafts are manufactured to the strictest tolerances, rigorously tested and are checked for quality. The Thumpr lobe profiles are designed to optimize the character and sound, while providing excellent stability and a very wide power range—specific profiles are developed uniquely for the intake and exhaust. Have you ever been to the races and heard how nasty the cams sound? The Thumpr series of cams give you everyday drivability but have that nasty race engine growl! COMP Cams competitive drive, superior engineering, and cutting-edge technology is what keeps them at the fore front from any other camshaft manufacturer. So ... pick the cam for your application, then add a set of hydraulic lifters—and you will be the talk of the town!
