The BMW 8544842 lower crankshaft counter balance shaft is a used genuine OEM part for the i3 and i3s. This shaft reduces engine vibration in the 0.6L (647cc) I2 Range Extender unit. A failing balance shaft can cause noticeable shaking or a rough idle, as it offsets the natural imbalance of the small twin-cylinder engine. Proper function keeps the REX running smoothly during charge-depleted operation.
