What does the +0.75mm sizing mean for these bearings?

The +0.75mm designation indicates that these bearings are intended for use when the engine's crankshaft has been machined undersize by 0.75mm. This allows for the correct bearing clearance to be re-established during an engine rebuild.

What is the construction of these main bearings?

These main bearings are constructed with a bimetal aluminum base. This type of construction is chosen for its good wear characteristics and ability to conform to the crankshaft journal.

Are these bearings a direct replacement for all engines listed?

These bearings are designed for specific Mitsubishi engine families (G25B, 4G54, 4G53) and are sized at +0.75mm. Always confirm your engine code and crankshaft condition before ordering to ensure proper fitment and application.

About this part

Product Details

Built with a bimetal aluminum base, these main bearings from King Engine Bearings are designed to handle the demands of your Mitsubishi G25B, 4G54, or 4G53 engine. This set is specifically sized at +0.75mm, meaning it's intended for crankshafts that have been machined down by that amount during an engine rebuild. Proper bearing clearance is crucial for oil flow and preventing metal-on-metal contact, which is why using the correct size and a well-made bearing is so important for engine longevity.

King Engine Bearings is a well-known name in engine components, and this set reflects their focus on reliable parts. The bimetal construction offers good wear resistance and conformability to the crankshaft journal. This main bearing set fits a wide range of vehicles, including popular models like the Dodge Ram 50, Mitsubishi Mighty Max, and Chrysler LeBaron, making it a solid option for many rebuild projects.
