What is the main function of connecting rod bearings?

Connecting rod bearings sit between the connecting rod and the crankshaft. Their primary job is to reduce friction and wear in this critical area, allowing the crankshaft to spin smoothly within the engine.

What does the 'MC' in the part number CR4125MC signify?

The 'MC' designation typically indicates that these bearings are standard size. This means they are intended for use with a crankshaft journal that is within the manufacturer's original specifications and has not been machined undersize.

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

While these bearings are well-built and designed to handle engine stresses, they are standard size. For heavily modified or high-performance engines where the crankshaft may have been machined undersize, you would need to select the appropriate undersize bearing set from King Engine Bearings.

About this part

Product Details

This is a set of connecting rod bearings from King Engine Bearings, designed for Subaru EJ20, EJ22, and EJ25 engines, including turbocharged models. These bearings are a crucial part of your engine's rotating assembly, sitting between the connecting rod and the crankshaft journal. They help reduce friction and wear, ensuring smooth operation and longevity of your engine.

King Engine Bearings uses a multi-layer overlay material with a high-strength steel backing for these bearings. This construction helps them handle the stresses of engine operation, especially in performance applications. The 'MC' in the part number indicates a standard size bearing, meaning it's intended for use with a crankshaft that is within factory specifications. If your crankshaft has been machined, you would typically need an undersize bearing, but these are for a stock or freshly machined to stock size journal.

When rebuilding or replacing engine components, using well-made bearings like these is important for the overall health of your engine. They are designed to fit right into the connecting rods and crankshaft journals of the specified Subaru engines.
