SUPER STROKER CRANKS (70mm)- Reworked from your core.
All Extreme strokers are fully nitrided for extra long bearing journal life. All cranks have standard Hayabusa rod journal sizes making bearing selection a snap. All strokers from Extreme are race balanced to less than 1/3 gram. Extreme is the only source for these micro balanced strokers.LIGHTNING & BALANCING - Extreme removes excess weight from the crankshaft and then balances it to race specs. Lightened crankshafts rev much quicker. The recontoured counterweights have less drag spinning through the oil mist resulting in more power to the wheel. Options include removal of the counterbalancer gear, and crankshaft stroking. These Crankshafts are sold as Exchange.
