What does the +.026mm size mean for these bearings?

The +.026mm designation indicates that these bearings are undersized by 0.026 millimeters. This size is used when the engine's crankshaft journals have been machined down by that amount during an engine rebuild to ensure proper clearance and fit.

What is PMaxBlack technology?

PMaxBlack is a technology developed by King Engine Bearings that enhances the bearing's ability to withstand higher loads. It's designed to improve the bearing's performance under stress, contributing to engine longevity.

What is the benefit of the Radialock design?

The Radialock design helps to maintain optimal crush height for the bearings. Proper crush height is important for ensuring the bearings seat correctly and maintain consistent oil clearance within the engine.
