High-Performance Cam Shafts
DME camshafts are designed using three decades of Dyno testing, racing, touring,
street rodding, and research with cams of all major manufacturers. Our familiarity
with the pros and cons of nearly every cam on the market, along with our vast
experience with different cylinder head characteristics, have given us a unique
insight into what the Harley-Davidson engine needs to accomplish the goals of the
customer. Every goal is different, and every combination of carburetion, ignition,
exhaust pipes, gearing, vehicle/rider weight, altitude etc. is different. We have
the knowledge and experience to recommend the "just right" camshaft for you. Keep
in mind that we sell all major brands of camshafts, and if we feel that one of them
is better for your application we will recommend it to you. Our goal is to provide
you with the best performance possible.
