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

The +0.25mm designation means these bearings are intended for use when the crankshaft journals have been machined down by 0.25mm. This is a common practice during engine rebuilds to ensure proper oil clearance and bearing function.

What is the construction of these bearings?

These connecting rod bearings are made with a bimetal aluminum base. This material is chosen for its ability to handle the high loads and operating temperatures within an engine's bottom end.

Are these bearings sold individually or as a set?

This is a set of connecting rod bearings. Typically, a set includes all the bearings needed for a specific engine's connecting rods during a rebuild.

About this part

Product Details

King Engine Bearings is known for making solid engine bearings, and this connecting rod bearing set is no different. If you're rebuilding the engine in a vehicle with a Mitsubishi 4D55T, 4D56T, or 4G52 engine, this set is designed to get it back to spec. These bearings are built with a bimetal aluminum base, which is a common and reliable material for handling the loads and temperatures found in an engine's bottom end.

This particular set is sized at +0.25mm, meaning it's meant for crankshaft journals that have been machined down by 0.25mm during an engine rebuild. Using the correct undersize or oversize bearing is crucial for ensuring proper oil clearance, which is key to oil pressure and bearing longevity. This set fits a wide range of vehicles, including models like the Dodge Ram 50, Mitsubishi Mighty Max, and Plymouth Arrow, among many others.
