What is the size of these connecting rod bearings?

These Clevite CB581P20 bearings are standard size. This means they are designed for crankshaft journals that are within the manufacturer's original specifications or have been machined back to standard size during an engine rebuild.

What is the main purpose of connecting rod bearings?

Connecting rod bearings sit between the crankshaft and the connecting rod. Their primary job is to create a low-friction surface that allows the rod to rotate smoothly around the crank journal while maintaining a precise oil clearance for lubrication and pressure.

Do these bearings come with new crankshaft bolts?

This product is a set of connecting rod bearings only. It does not include crankshaft bolts or any other installation hardware. You will need to source those separately if required for your engine rebuild.

Product Details

If you're rebuilding the engine in your classic Ford truck or car, or any vehicle with the 140, 144, 170, 200, or 250 cubic inch inline-four or inline-six engine, a new set of connecting rod bearings is a must. These Clevite CB581P20 bearings are designed to replace your worn-out originals, ensuring proper oil clearance and smooth operation between the crankshaft and connecting rods.

Clevite is a well-known name in engine components, and this bearing set is built to meet the demands of an engine rebuild. They are made with a specific overlay material that helps them conform to the crankshaft journal, which is important for maintaining consistent oil pressure and reducing friction. This particular set is sized at standard, meaning it's meant to be used with a crankshaft that is still within its original specifications, or has been machined back to standard size.

This set fits a wide range of vehicles, including many International Scout models from the 1970s, as well as various International trucks from the 1960s and 70s. Make sure to check the full fitment list to confirm compatibility with your specific application.
