The +0.75mm designation indicates that these bearings are 0.75 millimeters larger in diameter than the standard factory size. This is typically used when a crankshaft has been machined down to a larger size to correct wear or damage.

Are these bearings suitable for high-performance or racing engines?

These bearings feature a lead-free composite and are ideal for medium-load engines. For extreme high-performance or racing applications, it's always best to consult King Engine Bearings' specific product lines designed for those demands.

What material are these main bearings made from?

This main bearing set is constructed with a bi-metal aluminum material. This type of construction is common for main bearings, offering a good balance of strength and conformability.
