Soon it was time to drop in the forged Eagle crank (PN 434740006100). Since it's for the '10, it came with the required 58x reluctor wheel. The 4340 crank features a non-twist forging, and Eagle put it though a multi-stage heat-treatment process. Like the rods, it's fully tested and shot-peened. For improved oiling, the crank was also cross-drilled and has chamfered oil holes. Other features like a 0.125-inch radius on the rod and main journals and micro-polishing just make a good crank even better.
