Chris Rivas Rocket Cams for M8

4 Valves are better than 2!! The next progression of Harley-Davidson power is happening through four valves which have different requirements for the camshaft. Chris has come up with 4 new cam lobe profiles to squeeze the performance out of the smaller multivalve ports. Low lift 444, 464 and 474 cams are a direct bolt in application delivering the power where you expect it to be for your personal riding style. 544 cam is for the builder that wants the best possible power in his big inch motor. As with all cam changes, a performance intake, exhaust system, and EFI tuning are a must to get the full benefit from the cams. Many World Champions and speed record holders have trusted Chris for their power so when you want to explore the performance possibilities of your new Milwaukee 8 engine, who better to trust.
