This all new standard (3.000″ main journal, 2.500″ rod journal) crankshaft is made of 5340 nodular iron for strength and durability. 4.250″ stroke. Recommended for street and light racing applications.
Sealed roller bearing that drives into the back of a stock Oldsmobile automatic crankshaft. This bearing converts your crankshaft into a 4 speed application. The bearing is self aligning to compensate for bellhousing and transmission misalignment of about .010″ to .015″. You must shorten the tip of the input shaft so it won't bottom out in the crankshaft. On some models, the cranks are counterbored to accept the input shaft. This new unit can be driven into place with no machine work. This bearing assembly also fits any G.M. crankshaft in the converter locating hole and can be used when using a motor plate, transmission adapter, etc.. Fits all G.M. input shafts.
