What does the 1.0mm oversize mean for these bearings?

The 1.0mm oversize specification indicates that these bearings are designed for use when the crankshaft journals have been machined down by 1.0mm. This is a common practice when rebuilding an engine to correct for wear or damage on the original crankshaft surfaces.

What is the construction of these main bearings?

These main bearings feature a bimetal construction with an aluminum base. This type of bearing material is chosen for its ability to handle the loads and temperatures within an engine while maintaining proper oil clearance.

Are these bearings sold individually or as a set?

This product is a Main Bearing Set, meaning it includes all the necessary main bearings for the 1ZZFE engine to support the crankshaft.
