What does '+1.0mm' mean for these bearings?

The '+1.0mm' designation means these bearings are designed to fit crankshaft journals that have been machined down by 1.0 millimeter (approximately 0.040 inches). This is common when rebuilding an engine with worn or damaged connecting rod journals.

What is the overlay material?

King Engine Bearings uses a specialized overlay material that is formulated to reduce friction and wear. This material is designed to withstand the high pressures and temperatures encountered in engine operation, contributing to longer bearing life.

Do I need to machine my crankshaft to use these bearings?

Yes, these bearings are specifically made for crankshafts that have been machined down by 1.0mm (0.040 inches) to ensure a proper fit and function. If your crankshaft journals are still at standard size, you will need a standard size bearing set.
