What does the 'OS +.040' designation mean for these bearings?

OS +.040 means the bearings are 0.040 inches undersize. This indicates they are intended for a crankshaft that has been machined down by 0.040 inches, typically to remove wear or damage from the original bearing surfaces.

What is the advantage of the tri-metal construction?

The tri-metal design combines a steel backing for strength, a bronze-aluminum alloy for durability, and a lead-indium overlay for better embeddability. This construction helps the bearing manage oil flow and conform to the crankshaft for reduced friction and wear.

Are these bearings suitable for a performance build?

King Engine Bearings are well-regarded for their robust construction and performance in demanding applications. Their tri-metal design is engineered to handle the stresses of high-performance diesel engines.

About this part

Product Details

These King Engine Bearings are built with a unique tri-metal design, combining a steel backing for strength with a lead-indium overlay for improved embeddability and a bronze-aluminum alloy for durability. This combination helps manage oil film and reduce friction in your Ford Powerstroke 6.7L Diesel engine. They are specifically sized as a standard main bearing with a 0.040 inch undersize on the crank journals, meaning they are intended for crankshafts that have been machined down by 0.040 inches to clean up wear or damage.

The tri-metal construction is a key feature that helps these bearings perform well under the high loads and temperatures typical of a diesel engine. This design allows the bearing surface to conform slightly to the crankshaft, which is crucial for maintaining consistent oil pressure and preventing premature wear. King Engine Bearings are a popular choice for engine rebuilds where reliability and performance are important.
