What does '0.020 inch undersize' mean for these bearings?

This means the bearings are manufactured to be 0.020 inches smaller in diameter than standard size. This is typically used when the crankshaft journals have been machined down by 0.020 inches to clean them up or correct wear.

What is King's Tri-Armor technology?

Tri-Armor is a multi-layer coating applied to the bearing surface. It's designed to enhance durability and help reduce friction during engine operation, contributing to a longer bearing life.

Are these bearings suitable for high-performance applications?

King Engine Bearings is a popular choice for both performance and racing applications. Their bearings are well-built to handle the increased stresses and demands of a rebuilt or modified engine.

About this part

Product Details

In this kit, you get the upper main bearings for your Ford 370, 429, or 460 engine. These are specifically designed to be 0.020 inches undersize, which is important if you're re-machining your crankshaft journals to that specific size during an engine rebuild. King Engine Bearings is a well-known name in the performance and racing world, and their bearings are built to handle the demands of a rebuilt engine.

These bearings use King's Tri-Armor technology, which is a multi-layer coating designed to improve durability and reduce friction. The upper bearings are crucial for supporting the crankshaft and ensuring it spins smoothly within the engine block. When you're rebuilding a larger displacement Ford V8 like these, getting the right bearing clearance is key to a long-lasting engine, and these undersize bearings help you achieve that precision.
