What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.25mm during an engine rebuild. This ensures a proper fit and clearance with the modified crankshaft.

What is King's XP technology?

King's XP technology is an updated bearing design that focuses on improving oil flow characteristics and reducing friction within the engine. This can contribute to better lubrication and potentially longer bearing life.

What material are these bearings made from?

These main bearings are constructed from a tri-metal alloy. This type of material is chosen for its balance of strength, wear resistance, and ability to embed debris, making it suitable for demanding engine applications.
