Good To Know

Q: Can these bearings be used on crankshafts that have been ground down? A: No, these are standard size bearings and require an unground, factory-spec crankshaft.

Q: Why is cleanliness so critical during the installation of these bearings? A: Any microscopic debris trapped behind the bearing shell can cause high spots and lead to rapid engine failure.

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