RacingDiffs engineers spent months to develop the best possible inner profile design of the cover to accelerate the oil flow and improve the differential cooling, resulting in lowering the diff oil temperature by 15% on average.
Each design is thoroughly tested in real conditions on the car.

Besides supreme inner profile, RacingDiffs cover has 3 holes for oil instead of 2 like OEM covers. Lower hole is for draining and external pump inlet, middle one is for filling the LSD and the upper one is for the pump outlet. With this cover you can mount external oil cooling system without any modifications or welding.
It is very important to keep your differential temperature stable during any kind of endurance racing or long track days.

The 3 holes are of size M16x1.5 adapted for the AN connectors.
