Brian Crower CAN-AM X3 (17-up) EN40B BILLET CRANKSHAFT (73.5mm STROKE) BC5931-EN40 *Discontinued

EN40B billet. The ultimate Top Fuel Sand Outlaw crankshaft, CNC machined from EN40B billet round bar, the hardest material available with through hardening capabilities not possible on the standard 4340 steel.

Fully profiled counterweights are designed for reduced windage through the crankcase creating less oil resistance for better rpm potential. Requires internal balancing of the crank for operation
