Product Details

ACL has been making engine bearings for decades, and this main bearing set for your 1993-2002 Mitsubishi Mirage is one of their staples. These are high-performance main bearings designed for the 4G93 1834CC engine. They are built to handle the demands of performance applications, offering a solid option for rebuilding or upgrading your engine.

This set is +.25mm oversized, meaning they are designed to be used when the crankshaft journals have been machined down by 0.25mm to clean up wear or damage. Using oversized bearings like these ensures a proper, snug fit on a reconditioned crankshaft, helping to restore correct oil clearance and maintain oil pressure. ACL uses well-built materials to ensure durability and consistent performance under load.

When rebuilding your engine, using the correct size bearings is crucial for oil pressure and longevity. Make sure to verify your crankshaft journal size before ordering, as these are specifically for a +.25mm undersized journal.
