    These fit far more applications than listed. 2 years ago
    5out of 5stars

    These were just what I needed to get the clearances perfect on my new Forged crank in my Ford Duratec 2.3. All Duratec and EcoBoost 2.3's use the same main bearings, even though these show up here as incorrect for my application. The rod bearings are different, though my crankshaft is modified to use Duratec spec rods.
