High-Performance Camshafts

DME CamsDME 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.

Dave Mackie Twin-Cam Camshafts (2006 Dyna/2007 and Up)
