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

The +0.25mm designation indicates that these bearings are slightly larger than standard size. They are used when the engine's crankshaft journals have been machined down by 0.25mm to remove wear or imperfections. This ensures a proper fit and oil clearance in the rebuilt engine.

What is the construction of these main bearings?

These main bearings are made with a bimetal construction, featuring an aluminum base. This type of material is commonly used in engine bearings for its good thermal conductivity and wear characteristics.

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 for a complete engine installation. You will receive the full set needed for your engine's crankshaft.
