4SRC Billet 7075 CNC Front Diff Case Housing Kit

The 4SRC GT-R billet 7075 CNC front differential housing kit caters to cars with immense horsepower that can potentially overburden the standard casing and the engine block's mounting points.

Launching the GT-R can result in front differential failures, causing the engine's side to crack due to the diff tearing itself away from the mounts. By utilizing a solid CNC construction, the Billet diff casing is far more robust than the OE part's cast casing, minimizing the possibility of this disastrous outcome.
