What is the size of these connecting rod bearings?

These are standard size bearings, indicated by the 'AO/S2-10' in the part number. They are designed to be used with a crankshaft that is within factory specifications.

What does a connecting rod bearing do?

Connecting rod bearings are crucial for reducing friction between the crankshaft and the connecting rods. They allow the rods to rotate smoothly around the crank journals while maintaining a thin film of oil for lubrication.

Are these bearings suitable for a performance engine build?

These are standard size bearings, typically used for stock or mild performance rebuilds. For high-performance applications with modified crankshafts or significantly increased horsepower, custom-sized or performance-specific bearings might be necessary. Always consult your engine builder or performance specialist.

You get a full set of connecting rod bearings for your Ford V8 engine in this kit, which is essential for keeping your engine running smoothly. These bearings sit between the crankshaft and the connecting rods, reducing friction and wear.
