M Performance Limited-Slip Differential, 3.23 - F3X 335i/340i/435i/440i Manual
Increase the torque and traction delivered to the ground for faster acceleration and better handling. Genuine BMW M Performance part #33108659988.
A great upgrade for drivers looking for added acceleration and grip for their F30 335i/340i sedan and F32 435i/440i coupe!
A differential upgrade for your 335i/340i/435i/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 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 335i/340i/435i/440i differential uses a 3.23 gear ratio, standard for RWD and AWD cars with manual transmission. Other RWD models can use this ratio to improve acceleration, however, AWD xDrive models must retain their stock factory axle ratios.
This differential is shipped filled with fluid and with a new cover installed.
