What does the +0.50mm sizing mean for these bearings?

The +0.50mm sizing indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.50mm. This is a common practice during engine rebuilding to restore proper bearing clearances.

What is the advantage of a bimetal aluminum base bearing?

Bimetal bearings, often with an aluminum base, offer good conformability to the crankshaft surface and excellent embeddability for small debris. This construction helps maintain an oil film and resist wear in many engine applications.

Does this set include all the main bearings needed for an engine rebuild?

This is a main bearing set, which typically includes all the main bearings required for the crankshaft. It is important to verify that this set contains the correct number of bearings for your specific Mitsubishi 4G52 engine configuration.

About this part

Product Details

Built with a bimetal aluminum base, this King Engine Bearings main bearing set is specifically sized at +0.50mm for the Mitsubishi 4G52 engine. These bearings are crucial for the rotating assembly, providing a smooth, low-friction surface for the crankshaft to spin within the engine block. If you're rebuilding the bottom end of your engine, a properly sized and well-made bearing set like this is essential for ensuring proper oil clearance and long-term durability.

This set is designed to fit a range of vehicles, including models like the Dodge Colt, Plymouth Arrow, and Ford Ranger from various years. The bimetal construction offers good wear resistance and conformability, which helps maintain oil film integrity even under load. Having the correct undersize or oversize on your bearings, like the +0.50mm here, is critical for achieving the precise clearances recommended by the manufacturer after crankshaft machining.
