What is the main function of main bearings in an engine?

Main bearings sit between the engine block and the crankshaft. Their primary job is to support the crankshaft, allowing it to rotate smoothly while maintaining a thin film of oil to reduce friction and wear.

Does this main bearing set include all the necessary bearings for a 351M/351W engine rebuild?

This part number, MS1432HX, is for the main bearing set only. It includes all the main bearings needed to support the crankshaft. You will need to purchase rod bearings separately if your rebuild requires them.

What does the 'HX' designation mean for these Clevite bearings?

The 'HX' in the Clevite bearing designation typically refers to their special overlay technology. This overlay is designed to help the bearing conform to the crankshaft journal, which can improve oil retention and performance, especially on less-than-perfect surfaces.

Product Details

If you're rebuilding the engine in your classic Ford truck or SUV, like a 1978 Bronco or a 1985 F-150, a fresh set of main bearings is critical. These Clevite main bearings are made to fit Ford's 351M and 351W V8 engines from 1977 through 1998, providing the essential support your crankshaft needs to spin smoothly.

These bearings are well-built with a layered construction designed to handle the pressures and heat inside your engine. The HX series bearings feature a special overlay that helps them conform to the crankshaft journal, which is important for maintaining oil film and reducing wear, especially if your crankshaft isn't perfectly smooth. This helps ensure a solid foundation for your engine's rotating assembly.

When you're putting an engine back together, getting the main bearings right is key to its longevity. This set from Clevite is a popular choice for many Ford V8 rebuilds, offering a reliable component to get your engine running right.
