The COMP Cams Milwaukee 8 Mega 8 hydraulic roller camshaft is designed for 2017 Harley Davidson models, delivering exceptional torque and power across low to mid-range RPMs. This camshaft features a gross valve lift of .472 inches on both intake and exhaust valves, providing significant performance improvements. The valve lift at top dead center (TDC) measures .153 inches intake and .120 inches exhaust, with tappet lifts of .096 inches intake and .075 inches exhaust, ensuring optimal valve operation. With a duration of 222 degrees at .053 inches lift on the intake and 232 degrees on the exhaust, this cam promotes a strong, aggressive throttle response with a focus on low-end and mid-range pull. The valve timing opens at 16 degrees before TDC and 43 degrees after BDC for intake, closing at 26 degrees after TDC and 9 degrees after BDC for exhaust, enhancing torque delivery. The internal centerlines are set at 95 degrees for intake and 107 degrees for exhaust, with a lobe separation angle of 101 degrees, optimizing valve overlap and performance characteristics. Engineered to fit a variety of Harley Davidson models including the Road King, Street Glide, Ultra Limited, Fat Boy, and others, this camshaft is ideal for riders seeking a powerful, torque-rich upgrade that maintains reliable operation across a broad RPM range. Please note that this part is not carburetor approved and requires carb acknowledgment during installation. It is not suitable for emissions compliance; however, it is a proven choice for performance enthusiasts looking to maximize low and mid-range torque in their Milwaukee 8 engine.
