What does it mean that these bearings are 0.040 inches undersize?

This means the bearings are designed to fit a crankshaft that has been machined down by 0.040 inches. This is a common practice when rebuilding an engine to correct for wear on the crankshaft journals. You'll need to ensure your crankshaft has been properly machined to this specific undersize before installing these bearings.

Are these bearings sold individually or as a set?

This product is a set of connecting rod bearings. You will receive enough bearings to replace all the connecting rod bearings in your engine.

What is the main function of connecting rod bearings?

Connecting rod bearings act as a crucial interface between the connecting rod and the crankshaft. They allow the crankshaft to spin freely within the connecting rod while maintaining a thin film of oil to prevent metal-on-metal contact and reduce friction and wear.

Product Details

Already running a rebuilt or performance engine? This set of connecting rod bearings from ACL is the next piece of the puzzle. These bearings sit between your connecting rod and crankshaft, allowing them to spin smoothly while handling the immense forces generated during combustion. They're a critical wear item, and replacing them with a well-built set like these is essential for engine longevity, especially if you're pushing your engine harder than stock.

ACL has been making engine bearings for a long time, and these are built to handle the demands of your Chevrolet engine. They're designed to provide a consistent oil film, which is what keeps the metal surfaces from grinding against each other. This particular set is sized at 0.040 inches undersize, meaning it's intended for use with a crankshaft that has been machined down by that amount to correct for wear or to achieve a specific clearance. Make sure you've had your crankshaft measured and machined to the correct undersize before installing these bearings.
