What is the size of these main bearings?

These are standard size (STD) main bearings. They are designed for use with a crankshaft that has not been machined undersize.

What does a main bearing do?

Main bearings support the crankshaft within the engine block. They create a low-friction surface that allows the crankshaft to rotate smoothly while maintaining proper oil pressure.

Are these bearings suitable for a performance build?

This set is a well-built replacement for stock applications. For high-performance builds with significantly increased horsepower or RPMs, it's always best to consult with an engine builder to ensure the chosen components meet your specific needs.

About this part

Product Details

King Engine Bearings is known for making solid engine bearings, and this main bearing set for the Isuzu 4HK1-TCN is no different. When you're rebuilding or repairing your engine, the main bearings are critical for keeping the crankshaft spinning smoothly within the block. This set is designed to be a direct replacement for your stock bearings, ensuring proper fit and function.

These bearings are built to handle the demands of your engine. They are a standard size, meaning they are intended for use with an unmachined crankshaft. If your crankshaft has been ground undersize, you would need a different bearing size. Using the correct main bearings is essential for oil pressure and the overall health of your engine's rotating assembly.
