King AM-Series Main Bearings

4.24 out of 5 stars 33 Customer Reviews

King AM-Series main bearings are recommended for street or marine applications. These crankshaft bearings have superior embeddability, which provides greater macro-particle to reduce scratching of the crank journals and tearing or weakening of the Babbitt overlays. King AM-Series main bearings feature tolerance control to within plus or minus .0001—and they're lead-free, making them environmentally-friendly and user-safe. Hundreds of performance sets are available; order the replacement bearings designed to fit your vehicle.
