What does the 0.25 size designation mean for these bearings?

The '0.25' in the part number indicates that these main bearings are 0.025 inches undersize. This means they are slightly smaller than standard size and are intended for use with a crankshaft that has been machined down by 0.025 inches to ensure proper oil clearance.

Are these bearings environmentally friendly?

Yes, these bearings are made with a lead-free, environmentally safe composite material. This addresses concerns about hazardous materials often found in older bearing designs.

What is the typical application for these bearings?

These bearings are specifically designed for medium-load engines. They are well-suited for the Ford 232 engine found in a variety of Ford, Lincoln, and Mercury vehicles where consistent oil pressure and durability are important.
