What does the .050 size mean for these bearings?

The .050 size indicates that these bearings are undersized by 0.050 inches. This means they are designed to be installed on a crankshaft that has been ground down by 0.050 inches, typically done during an engine rebuild to clean up wear or damage.

What is the construction of these main bearings?

These bearings feature a bimetal construction with an aluminum base. This design helps them handle loads effectively and resist wear, which is important for the main bearings supporting the crankshaft.

Do these bearings come with installation hardware?

This product is a set of crankshaft main bearings only. Installation hardware, such as main bearing cap bolts or studs, is not included and would need to be sourced separately if required for your engine rebuild.

Product Details

If you're rebuilding the engine in your classic Ford or Mercury, getting the crankshaft main bearings right is crucial. This set from King Engine Bearings is specifically made for Ford's 239, 256, 272, and 292 cubic inch engines, and it's sized .050 inch to account for crankshaft grinding during a rebuild. These bearings are built with a bimetal construction, meaning they have an aluminum base for good load-carrying capacity and wear resistance.

King Engine Bearings is a well-known name in engine components, and this set is designed to fit a wide range of vehicles from the mid-50s to the mid-60s, including popular models like the Ford F-100, Ford Fairlane, and Mercury Monterey.

Proper installation ensures smooth crankshaft rotation and helps protect your engine from premature wear.
