A great upgrade for drivers looking for added acceleration and grip for their F22 M240i coupe, F30 340i sedan and F32 440i coupe!

A differential upgrade for your M240i/340i/440i delivers performance beyond the original factory spec. Only M models received limited-slip differentials which left the car with just electronic traction control to regulate wheel spin. The F22/F3X becomes a more capable performance car when both rear wheels are maximizing traction. A limited-slip differential seamlessly and immediately transfers torque away from a spinning tire and moves it to the tire on the opposite side. With a M Performance differential 30% of torque is transferred to the opposite tire (and then electronic traction control steps in). The system works independently, and limits interference, of traction control which will cut power or apply the brakes. The car feels faster because there is more traction and grip. As a Genuine BMW part, this M Performance differential is an easy and direct swap of your original diff and carries all of the same warranty and service requirements as any other BMW differential.

This M240i/340i/440i differential uses a 2.81 gear ratio, standard for cars with automatic transmission.

This differential is shipped filled with fluid and with a new cover installed.
