What does the .010 size mean for these main bearings?

The .010 size indicates that these bearings are undersized by 0.010 inches. This means they are intended for use with a crankshaft that has been professionally machined down by 0.010 inches to correct for wear or to achieve specific bearing clearances during an engine rebuild.

What is the pmaxkote coating and why is it beneficial?

Pmaxkote is a polymer coating developed by King Engine Bearings for their racing line. It helps to reduce friction and improve wear resistance, especially during the initial engine break-in period and under higher stress conditions common in performance applications.

Are any other parts needed for installation besides the bearings?

Yes, for a complete engine rebuild, you will typically need a new oil pump, oil filter, and potentially new main bearing cap bolts or studs. It is also essential to have your crankshaft professionally machined to the correct .010 undersize before installing these bearings.

Product Details

If you're rebuilding the bottom end of your Ford 260, 289, 302, or 5.0L Windsor engine, a solid set of main bearings is crucial for proper crankshaft support. This set from King Engine Bearings is designed to handle the demands of these classic Ford V8s, ensuring your engine runs smoothly and reliably.

These bearings feature King's pmaxkote racing line polymer coating, which is a popular choice for performance builds. This coating helps reduce friction and wear, especially during the critical break-in period and under demanding conditions. They are also a .010 inch undersize, meaning they are intended for use with a crankshaft that has been machined down by 0.010 inches to correct for wear or to achieve specific clearances. This set includes all five main bearings needed for your engine.

This bearing set fits a wide range of Ford vehicles from the 1960s through the 1990s, including models like the Ford Bronco, F-100, and various Econoline vans. Always confirm fitment for your specific application and ensure your crankshaft has been properly machined to the .010 undersize before installation.
