This item is for a set of main bearings. You will have enough to rebuild one engine.
Black Diamond engine bearings combine the strength of a copper-lead alloy layer with steel backing and an electroplated babbitt metal. The steel backing provides strength and durability; the babbitt overlay provides the critical surface characteristics of slipperiness and conformability. This ideal design has properties not even found in many original equipment bearings. These bearings are available is undersizes also if you need to regrind your crankshaft.
