What does the +0.75mm sizing mean for these bearings?

The +0.75mm sizing indicates that these bearings are slightly larger than standard size. This is typically used when the crankshaft journals have been machined down by 0.75mm to clean up wear or damage. Always confirm your crankshaft journal size before ordering.

What is the advantage of a bimetal aluminum base bearing?

Bimetal bearings with an aluminum base offer good load-carrying capacity and conformability, meaning they can adapt to slight imperfections in the crankshaft. This construction is known for its durability and compatibility with modern engine oils.

Does this main bearing set come with all the necessary components for installation?

This listing is for the main bearing set only. It does not include other components like crankshafts, seals, or gaskets. You will need to ensure you have all other necessary parts and hardware before beginning your engine rebuild.
