What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.25mm. This is a common practice during engine rebuilds to ensure proper clearance when the crankshaft has been ground undersize.

What is the construction of these main bearings?

These main bearings are constructed with a bimetal design, featuring an aluminum base. This construction is chosen for its ability to conform to the crankshaft and distribute loads effectively, while providing good wear resistance.

Are these bearings sold individually or as a set?

This product is a main bearing set, meaning it includes all the necessary main bearings required to service the crankshaft for the specified engine.
