MELONIZED Pinned HD Intermediate Shaft - 4340 STEEL

Melonizing, (which is a trade name for Salt Bath Nitriding,) is a process where a nitrocarburized layer is formed consisting of the outer compound layer (iron nitride) and the diffusion layer thereunder. This compound layer consists of a blend of iron, nitrogen, carbon and oxygen. Due to its microstructure, the compound layer does not possess metallic properties. It is particularly resistant to wear, seizure and corrosion, as well as being stable almost to the temperature at which it was formed. Compared with plasma or gas nitro-carburizing, compound layers with the highest nitrogen content can be obtained by Melonizing. Layers with a high nitrogen content give better protection against wear, and in particular corrosion, than those with a low content. In plain English, this means the heat treated gear is especially hard and resistant to wear, making them the longest life option available for use with both billet roller cams and steel flat tappet cams. If you are replacing the gear on a cam which has already been run with a steel or bronze gear, you must make sure to THOUROUGHLY clean all residue off the cam gear, otherwise it will act like lapping compound and wear into the gear. To avoid any possibility of this, it's best to use these with a brand new cam. In addition to the Melonizing, these feature all the same heavy duty features as our standard pinned shafts, including a heavy duty steel gear which is pinned to the shaft, as well as a radiused taper for extra strength where the shaft transitions into a hex drive for the oil pump. We also use 4340 non twist steel for the shaft itself, (the same material as our 1000 horsepower cabable crankshafts are made from.) These work great with our high volume and high pressure oil pumps. Don't forget a new bushing as well, (also offered.)
