What does the +0.25mm size mean for this main bearing set?

The +0.25mm designation indicates that these bearings are intended for use with a crankshaft that has been machined down by 0.25mm. This is common when a crankshaft needs to be resurfaced due to wear or damage during an engine rebuild.

What is the benefit of King's specialized overlay material?

King's specialized overlay material is designed for good embeddability, meaning it can accommodate minor imperfections on the crankshaft surface. It's also formulated to be compatible with different crankshaft finishes, helping to ensure consistent oil pressure and a long service life.

Are these bearings suitable for high-performance applications?

King Engine Bearings is known for producing bearings used in performance and racing applications. This set is built to provide proper crankshaft support and oil flow, which are critical for the reliability of both stock and modified Gen III Hemi engines.
