What does the 0.020 inch undersize mean for these bearings?

The 0.020 inch undersize indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.020 inches. This is common during engine rebuilds to clean up worn or damaged surfaces.

What is the material composition of these Clevite bearings?

Clevite bearings are known for their multi-layer construction. This design typically includes a steel backing for strength, a bronze or aluminum intermediate layer, and a bearing surface material that is conformable to protect the crankshaft.

Do these bearings come with the necessary hardware for installation?

This listing is for the main bearing set only. Installation typically requires specific tools and adherence to torque specifications found in your vehicle's service manual. Hardware is not typically included with main bearing sets.

Product Details

These Clevite main bearings are built with a 0.020 inch undersize, meaning they are designed to compensate for crankshaft journals that have been machined down during a rebuild. They are specifically made for Ford 351M, 351W, and 400 V8 engines from 1977 through 1993. Proper main bearing function is critical for supporting the crankshaft, maintaining oil clearance, and ensuring the engine runs smoothly and lasts. If you're rebuilding the bottom end of one of these popular Ford V8s, getting the right bearings is a key step.

Clevite uses a multi-layer bearing material construction that balances strength with conformability, helping to protect the crankshaft journals from wear. This design helps to maintain consistent oil pressure and reduce friction, which are vital for engine health. They fit a wide range of Ford trucks and cars from the late 70s through the early 90s, including models like the F-150, Bronco, and E-Series vans. Installing these bearings requires careful attention to cleanliness and proper torque specifications, as outlined in your vehicle's service manual.
