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

The +0.25mm sizing indicates that these bearings are designed to be used when the crankshaft journals have been machined down by 0.25mm (approximately 0.010 inches). This is common during engine rebuilds when the crankshaft has been ground to remove imperfections or to achieve a specific clearance.

What is a bimetal bearing and why is it used?

A bimetal bearing uses two layers of different materials. In this case, it has an aluminum base layer for good heat dissipation and a bearing overlay for wear resistance. This construction is popular for main bearings because it balances durability with the ability to manage the heat generated during engine operation.

Are these bearings sold individually or as a set?

This product is a main bearing set, meaning it includes all the necessary main bearings to rebuild the crankshaft main journals for one engine. You will receive multiple bearings as part of this kit.

About this part

Product Details

If you're rebuilding the engine in your Chrysler, Dodge, or Plymouth vehicle with a 2.2L engine, this King Engine Bearings Main Bearing Set is a solid option. These are bimetal bearings, meaning they have an aluminum base, which is a common and effective material for main bearings in many applications. This particular set is sized at +0.25mm, so it's intended for use when the crankshaft journals have been machined to that specific undersize.

King Engine Bearings is a well-known name in the engine parts world, and these bearings are built to meet the demands of an engine rebuild. The bimetal construction helps manage heat and provides a good bearing surface for the crankshaft. They are designed to fit right into the engine block, making installation straightforward for a mechanic who is already familiar with engine assembly.

This set is designed to fit a wide range of vehicles from the early 1980s through the mid-1990s, including popular models like the Dodge Caravan, Plymouth Reliant, and Chrysler LeBaron. Always ensure you have the correct crankshaft journal size before ordering, as these are an undersize bearing.
