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

The +0.50mm sizing indicates that these bearings are 0.50mm larger than the standard size. This is used when the engine's crankshaft has been machined down by 0.50mm during a rebuild to ensure proper oil clearance.

What is the construction of these main bearings?

These main bearings feature a bimetal construction with an aluminum base. This design helps with heat management and provides a strong surface for the crankshaft to rotate against.

Are these bearings a direct replacement for all 4G63 engines?

This set is specifically for 4G63 and 4G64 DOHC engines and is sized at +0.50mm. Always confirm your engine type and the required bearing size before purchasing, especially if your crankshaft has been machined.

About this part

Product Details

Built with an aluminum base, this main bearing set from King Engine Bearings is specifically made for Mitsubishi 4G63 and 4G64 DOHC engines. These bearings are sized at +0.50mm, meaning they are 0.50mm larger than standard, which is crucial when rebuilding an engine with a crankshaft that has been machined down to match this size. This set is designed to fit a range of vehicles, including models like the Dodge Ram 50, Eagle Talon, and Mitsubishi Eclipse, among others.

The bimetal construction, featuring an aluminum base, helps manage heat and provides a solid foundation for the bearing surface. When you're rebuilding the bottom end of your engine, getting the right bearing size is critical for proper oil clearance and long-term durability. These bearings are a well-built option for ensuring your engine's crankshaft is properly supported.
