What does the '001' size designation mean for these bearings?

The '001' in the part number indicates that these main bearings are 0.001 inch undersize. This is typically used when the engine's crankshaft has been machined and polished to a specific undersize to achieve proper oil clearance and bearing crush.

What is the 'SI' designation in the part number?

The 'SI' in the part number typically refers to the standard size bearing. However, this specific set is stamped as 001, indicating it is the 0.001 inch undersize version of the standard size bearing.

What is the tri-metal material used in these bearings?

Tri-metal bearings consist of three layers: a steel backing for strength, a middle layer of copper-lead alloy for heat dissipation and embeddability, and a thin overlay of babbitt (a soft alloy) for excellent conformability and resistance to scoring.

About this part

Product Details

These King Engine Bearings main bearings are made with a high-performance tri-metal material, offering a strong and durable surface for your Ford Godzilla 7.3L engine's crankshaft. The 'SI' in the part number indicates the standard size bearing, but this specific set is stamped as 001, meaning it's 0.001 inch undersize. This is important if your crankshaft has been recently machined and polished to a specific undersize specification, ensuring a proper crush and oil clearance.

King uses a unique overlay technology that helps these bearings resist wear and fatigue, even under demanding conditions. The tri-metal construction provides excellent embeddability, meaning small debris can be absorbed without causing damage to the bearing or the crankshaft. This set is designed to fit right into your Godzilla engine, providing a solid foundation for its rotating assembly.
