What does the 0.010X sizing mean for these bearings?

The '0.010X' in the part number indicates that these main bearings are 0.010 inches undersize. This means they are intended for use with a crankshaft that has been machined down by 0.010 inches to account for wear or to achieve a specific clearance.

What is the alecular material used in these bearings?

Amolecular is a bi-metal material used by King Engine Bearings in their racing line. It's chosen for its strength and ability to handle higher loads, making it a good choice for performance-oriented engine builds.

Are these bearings suitable for a daily driver or only for racing?

While part of King's racing line and made with alecular material for strength, these bearings can be a solid option for a performance-oriented daily driver. They offer improved durability over standard bearings, but it's always best to consider your specific engine's use and build.

Product Details

Built with an alecular bi-metal construction, this King Engine Bearings main bearing set is part of their racing line. It's designed for Ford 260, 289, and 302 5.0L Windsor engines, and this specific set is 0.010 inch undersize, meaning it's intended for crankshafts that have been machined down by that amount during a rebuild.

This set is a solid option if you're rebuilding a performance-oriented Ford V8. The alecular material is known for its strength and ability to handle higher loads, making it suitable for engines that see more demanding use. It's a direct replacement for the stock main bearings, but with an improved material composition for those looking for a bit more durability under stress.

This bearing set fits a wide range of Ford vehicles from the 1960s through the 1990s, including models like the Ford Bronco, Ford E-Series vans, and Ford F-Series trucks. Always confirm fitment for your specific application, especially when dealing with older or modified engines.
