What does the '+0.75' size mean for these bearings?

The '+0.75' designation indicates that these bearings are 0.75mm (approximately 0.030 inches) undersize. This means they are intended for use when the crankshaft journals have been machined down by that amount during an engine rebuild.

What is the construction of these main bearings?

These bearings feature a bimetal construction, which means they have a strong aluminum base. This design helps with heat dissipation and oil retention, crucial for proper engine lubrication and longevity.

Are these bearings sold individually or as a set?

This product is a main bearing set. It includes all the necessary main bearings required to properly support the crankshaft in the specified engine applications.
