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

The +0.75mm sizing indicates that these main bearings are intended for use when the engine's crankshaft journals have been machined down by 0.75mm. This is a common practice during engine rebuilding to ensure a precise fit on worn or resurfaced journals.

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

These bearings are described as ideal for medium-load engines. For high-performance or racing applications with significantly higher loads and RPMs, it's always best to consult King Engine Bearings' specific product lines designed for those demanding conditions.

What is the benefit of the lead-free composite material?

The lead-free composite material is environmentally safe, aligning with modern regulations. It's also chosen for its performance characteristics in medium-load engines, contributing to the bearing's overall effectiveness and longevity.
