AM-Series Bearings

King AM-Series 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.

AM is the softest bi-metal material. It contains 20% of tin, 1% of copper and no silicon. AM bearings are used in the passenger cars with low and medium load gasoline engines.
