Sealed Power Engine Crankshaft Main Bearing Set P/N:960M 40
Sealed 960M 50 main bearing set for the 1958-1962 Chevrolet Impala 6-cylinder 3.8L and other vehicles supports the crankshaft in the block while it turns. It is built to exacting tolerances and OE-level specifications for classic engine rebuilds.
Worn crankshaft main bearings can show up as a knock from the bottom of the engine, low oil pressure or metal particles in the oil. These signs alone do not prove the bearings are the problem, since a worn oil pump can also lower oil pressure.
This set is a direct-fit replacement for a wide range of Chevrolet, GMC and Pontiac models, including the 1960-1962 Chevrolet Suburban 6-cylinder 3.8L and the 1961-1962 Suburban 6-cylinder 4.3L, and the 1960-1963 Chevrolet K20 Pickup 6-cylinder 3.8L and the 1961-1962 K20 Pickup 6-cylinder 4.3L. Open the "Vehicles it fits" section to check your exact model and engine.
