About this part

Product Details

These main bearings from King Engine Bearings are built with a high-performance tri-metal material, offering a strong and durable surface for your Ford Ecoboost 1.0L M1DA engine. This specific set is machined to be 0.05 undersize, which is crucial when you're rebuilding or repairing an engine where the crankshaft journals have been machined down to match this size.

King uses a unique overlay formulation that's designed to withstand the pressures and heat generated in modern engines. The tri-metal construction means you get a solid foundation for your crankshaft, helping to ensure smooth operation and longevity. When installing these, make sure your crankshaft journals are cleaned and precisely measured to confirm they are within the 0.05 undersize specification. This attention to detail during installation is key to getting the most out of these well-built bearings.
