Good To Know

Q: Does this crankshaft assembly come with connecting rods? A: A complete crankshaft assembly is sold with the rods already fitted to the crank, which simplifies installation during a bottom-end rebuild.

Q: Should I replace bearings at the same time? A: Replacing main and rod bearings alongside a new crankshaft assembly is standard practice, since worn bearings can quickly damage fresh crank journals.

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