What does the +0.50mm sizing mean for these bearings?

The +0.50mm sizing indicates that these main bearings are larger than the standard size. They are intended for use when the engine's crankshaft journals have been machined to be 0.50mm larger in diameter during an engine rebuild.

What is the SI material used in these bearings?

The SI material is a high-performance overlay developed by King Engine Bearings. It is designed to provide good durability and resistance to wear, which is important for the longevity of the engine's rotating assembly.

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 rebuild for the specified Toyota 1Zr-Fe engine.
