Specs At A Glance

Good To Know

Q: Can I replace just one main bearing? A: Engine builders usually replace main bearings as a set during a rebuild to keep clearances even across all journals.

Q: Are these bearings sized as standard or oversize? A: Confirm journal size and any machine work already done to the crank before ordering so you get the correct bearing.

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