What does the '0.05' in the part number signify?

The '0.05' indicates that these connecting rod bearings are 0.05 inches undersize. This means they are designed for use with a crankshaft that has been machined down by 0.05 inches during an engine rebuild to ensure proper oil clearance.

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

The 'MC' in the part number signifies King Engine Bearings' high-performance racing alloy. This material is known for its increased strength and durability, making it suitable for demanding engine applications.

What is the advantage of the tri-metal construction?

The tri-metal construction, typically a steel backing with copper-lead and lead-tin overlays, provides a strong foundation capable of handling high loads and temperatures. This design helps ensure consistent performance and longevity for the bearings.

About this part

Product Details

These King Engine Bearings are built with a unique tri-metal construction, combining a steel backing, a copper-lead overlay, and a lead-tin overlay. This advanced material setup is designed to handle the high loads and temperatures found in performance Ford V8 engines, specifically the 4.6L and 5.4L SOHC variants. The 'MC' in the part number signifies King's high-performance racing alloy, which offers improved strength and durability over standard bearings.

This set is precisely machined to be 0.05 inches undersize, meaning they are intended for crankshafts that have been machined down by that amount during an engine rebuild. Using the correct bearing size is critical for establishing proper oil clearance, which ensures the crankshaft spins freely without excessive wear. King's attention to detail in their manufacturing process helps ensure these bearings fit right and perform reliably under demanding conditions.
