What does the '0.05' in the part number signify?

The '0.05' indicates that these bearings are 0.05mm undersize. This means they are intended for use when the crankshaft journals have been machined down by 0.05mm during an engine rebuild.

Are these bearings suitable for high-performance or turbocharged engines?

Yes, these bearings are designed for Subaru EJ20, EJ22, and EJ25 engines, which often include turbocharged variants. They feature King's specialized overlay material, which is built to handle the stresses associated with performance applications.

What is the primary function of connecting rod bearings?

Connecting rod bearings sit between the crankshaft and the connecting rod. Their main job is to reduce friction and wear in this critical area, allowing the crankshaft to rotate smoothly while transferring power from the pistons.

About this part

Product Details

King Engine Bearings is well-known for making solid internal engine components. This set of connecting rod bearings is made for Subaru EJ20, EJ22, and EJ25 engines, including turbocharged models. These bearings are crucial for reducing friction between the crankshaft and connecting rods, helping your engine run smoothly and efficiently.

This particular set is 0.05mm undersize, which is important if you're rebuilding an engine where the crankshaft journals have been machined down to this size.
