What does the 0.025 inch undersize mean for these bearings?

The 0.025 inch undersize indicates that these bearings are designed to fit a crankshaft that has been machined down by 0.025 inches. This is common during engine rebuilding when crankshaft journals are worn and need to be reconditioned to a specific size.

What is the XP tri-metal material?

King's XP tri-metal material is an advanced bearing surface composed of three layers. This construction offers improved load capacity and wear resistance, making it well-suited for high-performance applications where engine stress is greater than stock.

Are these bearings suitable for a stock engine rebuild?

While these bearings are well-built, their 0.025 inch undersize means they are intended for a specific crankshaft condition. They are best suited for performance builds or engines where the crankshaft has been machined to this size.

About this part

Product Details

These King Engine Bearings main bearings are precisely sized at 0.025 inches undersize, meaning they're intended for crankshafts that have been machined down by that amount during an engine rebuild. They are specifically made for Ford GT500 blocks, ensuring a proper fit for that application. King uses their advanced XP tri-metal material, which is known for its strength and ability to handle high loads and temperatures, making these a solid choice for performance builds where the stock bearings might not hold up.

The tri-metal construction offers improved oil clearance and better wear resistance compared to standard bearings. This is crucial for maintaining proper oil pressure and protecting the crankshaft journals under demanding conditions. When you're rebuilding a performance engine like the one found in a GT500, using well-built bearings that can handle the extra stress is key to a reliable and long-lasting build.
