Engine Crankshaft – GM (19185340)

Engine Crankshaft turns motion in the engine or transmission. Journal diameter and surface finish determine whether it runs quietly, and both are checked against the bearing it sits in.

Replace the Engine Crankshaft when noise appears at a frequency tied to camshaft or crank speed, or when end float is out of specification. Check that the oil supply passage is clear before fitting.

The Engine Crankshaft in this listing carries part number 19185340 and sits in the Crankshafts & Bearings category. The number stamped on the original part is the only reliable cross-reference.

This is genuine GM stock, supplied for the Engine Crankshaft with the manufacturer number intact so the reference on the box matches the catalogue.
