Description

This heavy-duty replacement engine crankshaft is manufactured to precision OE standards to restore internal bottom-end structural integrity and smooth rotational dynamic balance in BMW 2.0L 4-cylinder petrol engines. Precision-machined from high-strength forged steel/alloy, this unit is built to withstand extreme mechanical stress, heat, and torsional loads. It directly replaces damaged, scored, or snapped original crankshafts caused by oil starvation, spun rod/main bearings, or extreme fatigue. Replacing the crankshaft eliminates severe bottom-end knocking, restores oil pressure stability, and prevents catastrophic engine block destruction.

Application Note: Specifically engineered for BMW 2.0-liter naturally aspirated 4-cylinder DOHC petrol engines (N42B20, N46B20, and N43B20 engine codes). Important Fitment Note: Crankshaft bearing shells, connecting rod bearings, and front/rear main crankshaft oil seals must be inspected and replaced during installation. Flush all internal engine oil galleries and inspect the oil pump thoroughly before fitting to prevent immediate bearing score or oil starvation.
