The ARB Black Differential Cover has been designed to add style, but more importantly it will add more reinforcement to your differential especially on trail impacts with large rocks and tree stumps. This differential cover has been manufactured using high tensile nodular iron, and has been engineered to protect the differential, as well as ring and pinion from road hazards.
Additional features include a computer optimized cross brace design that increases the structural rigidity of the whole axle. The housing strength keeps the ring and pinion gear meshing on the flat faces of the teeth, which increases the ring and pinion life and overall maximum load strength. High power neodymium magnets are used in both the drain plug and dip stick which will collect metallic wear particles as the vehicle moves. The magnet location on the dipstick allows the oil to be checked for tell-tale signs of internal damage, or prolonged carrier bearing life due to extra support to the bearing alignment.
This particular differential bearing cover will come powder-coated a nice red finish that will provide protection against corrosion.
