Good To Know

Q: Does this crankshaft require balancing before installation? A: While the crankshaft is dynamically balanced at the factory, we recommend checking the balance with your specific piston and connecting rod assembly prior to final engine assembly.

Q: Are main bearings and connecting rod bearings included with this crankshaft? A: No, this is the crankshaft only. You must purchase the appropriate size main and rod bearings separately based on your block clearance measurements.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
