What does the 0.75mm undersize mean for my engine rebuild?

The 0.75mm undersize indicates that these bearings are meant for a crankshaft that has been machined down by 0.75mm. This is typically done during an engine rebuild to correct wear, damage, or out-of-round conditions on the crankshaft journals.

What is the advantage of the bi-metal aluminum material?

The bi-metal aluminum construction offers a good balance of strength and conformability, making it suitable for medium-load engines. It's also a lead-free composite, which is considered more environmentally safe than older bearing materials.

Does this bearing set come with all the necessary main bearings for my engine?

This is a main bearing set, which includes all the main bearings required for the crankshaft installation in your specified Dodge Cummins engine. Always refer to your vehicle's service manual for complete engine assembly instructions.

About this part

Product Details

If you're rebuilding the engine in your 1989-2012 Dodge Cummins diesel, you'll want a solid set of main bearings. This is the 0.75mm undersize main bearing set from King Engine Bearings, designed for the 5.9L and 6.7L inline 6-cylinder engines found in models like the D250, Ram 2500, and Ram 3500.

King has been specializing in engine bearings since 1960, focusing on providing well-built components. This particular set uses a bi-metal aluminum material, which is a lead-free composite ideal for medium-load engines. The 0.75mm undersize means these bearings are intended for crankshafts that have been machined down by 0.75mm during a rebuild to correct wear or damage. Using the correct undersize bearing is crucial for proper oil clearance and engine longevity.
