What is the main function of crankshaft main bearings?

Main bearings support the crankshaft within the engine block. They create a thin film of oil that separates the spinning crankshaft from the stationary block, reducing friction and wear while maintaining precise alignment.

Does this bearing set include rod bearings?

No, this kit contains only the main bearings for the crankshaft. You will need to purchase a separate set of connecting rod bearings if your engine rebuild requires them.

What engine displacements are covered by this bearing set?

This ACL main bearing set is designed for Chevrolet V8 engines with 265, 283, 302, and 327 cubic inch displacements.

Product Details

You get a full set of main bearings in this kit, which means one box handles the critical crankshaft support for your engine rebuild. These ACL bearings are built to fit Chevrolet V8 engines from 1955 through 1967, covering displacements like the 265, 283, 302, and 327 cubic inches. Proper main bearing function is essential for keeping your crankshaft spinning smoothly and within its intended tolerances, preventing premature wear and ensuring the longevity of your engine.

ACL has been making engine bearings for a long time, and this set is well-built for the job. They are designed to provide the correct clearance and oil film between the crankshaft and the engine block, which is crucial for reducing friction and heat. When you're rebuilding an engine of this era, using a reliable bearing set like this from ACL is a solid choice to ensure your build is done right.

This set is intended for the main bearings only. Make sure you have all the other necessary components for your engine rebuild, such as rod bearings, piston rings, and gaskets, before you begin.
