What does the +0.25mm size mean for these bearings?

The +0.25mm designation indicates that these bearings are slightly larger than standard size. This is typically used when the crankshaft journals have been machined down by 0.25mm to clean up wear or damage, ensuring proper clearance for the new bearings.

What is the Tri-M+ enhanced babbit overlay?

The Tri-M+ overlay is a layer of babbit material applied to the bearing surface. It's designed to provide improved embeddability and conformability, which helps the bearing adapt to the crankshaft and maintain a consistent oil film, especially under load.

Are these bearings suitable for a performance-built engine?

These bearings are described as ideal for medium-load engines. For high-performance or heavily modified engines, it's always best to consult with a performance engine builder to ensure the bearing material and design meet the specific demands of your build.

Product Details

If you're rebuilding the engine in your 2004-2010 Ford E-350 Super Duty with a 6.0L or 6.4L Powerstroke diesel, these crankshaft main bearings from King Engine Bearings are a solid option. They are specifically sized at +0.25mm, which is important for ensuring proper clearances after crankshaft machining. King has been specializing in bearings since 1960, focusing on supplying well-built engine bearings.

These bearings use a tri-metal copper-based material with a Tri-M+ enhanced babbit overlay. This construction is well-suited for medium-load engines like the Powerstroke diesel. Having the correct main bearings is crucial for supporting the crankshaft and maintaining oil pressure throughout the engine.
