What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.25mm. This is a common practice during engine rebuilding to clean up worn or damaged journals.

What is the advantage of a 3/4 groove design?

The 3/4 groove design in these bearings helps to distribute oil more effectively around the crankshaft journal. This improved oil flow is important for lubrication and reducing friction.

Are these bearings a direct replacement for all Mitsubishi 4G52 engines?

This set is an optional replacement for the MB5441AM. While it fits the Mitsubishi 4G52 engine, always confirm that this specific bearing size and design are correct for your engine's condition and rebuild specifications.

Product Details

King Engine Bearings is known for making solid engine bearings, and this Main Bearing Set for the Mitsubishi 4G52 engine is no different. If you're rebuilding the bottom end of your engine, these bearings are a crucial part of ensuring smooth operation and proper oil clearance. This set is sized at +0.25mm, meaning it's designed to be used when the crankshaft journals have been machined down by that amount to clean them up.

They are an optional replacement for the MB5441AM, offering a 3/4 groove design which can help with oil distribution. This set fits a range of vehicles, including models like the Dodge Colt, Dodge D50, and Ford Ranger from various years.
