What does the '+1.0mm' size indicate for these bearings?

The '+1.0mm' indicates that these main bearings are 1.0 millimeter larger in diameter than the standard size. This is necessary when the crankshaft journals have been ground down during an engine rebuild to remove wear or damage.

What is the construction of these main bearings?

These main bearings feature a bimetal construction, meaning they are made of multiple layers of metal. They are built on an aluminum base, which is common for performance and durability in modern engine bearings.

Are these bearings compatible with all Mitsubishi 4G63 engines?

This specific bearing set is designed for Mitsubishi 4G63 and 4G63T engines manufactured up to 1992. Always verify your engine's specific model and year range before purchasing.
