What does '0.025mm oversized' mean for these bearings?

This means the bearings are slightly larger than the standard factory size by 0.025 millimeters. This is typically used when the crankshaft journals have been machined down (ground) to ensure a proper, tight fit and correct oil clearance during an engine rebuild.

Are these bearings suitable for a stock engine rebuild?

Yes, these are high-performance bearings, but they are designed to meet or exceed OEM specifications for fit and function. They are a solid option for both stock rebuilds and engines that have been modified for increased performance.

What is the typical application for these bearings?

These bearings are commonly used in performance engine builds for Mitsubishi vehicles equipped with the 4G63 and 4G64 7-bolt engines, such as the DSM Eclipse and early model Lancers and Galants.
