MJX HYPER GO Full Metal Gear Differential Box For 16207/16208/16209/16210

This listed part is made with Powder metallurgy (PM), a manufacturing process that creates metal parts from metal powders through compaction and sintering. This versatile technique offers advantages like material efficiency, complex shape capabilities, and high dimensional accuracy, making it ideal for applications in the automotive, aerospace, and medical industries. The process involves preparing and blending metal powders, compacting them into a desired shape, and then heating them below their melting point to metallurgically bond the particles. This part does not contain steel. It says "all metal". it's mainly soft alloys and aluminum. This part can handle most 25C rated batteries in cars sold here. Caution: If you want to run Lipo batteries rated 50C or higher, this plastic-alloy differential will have limited life. Upgrade to an all steel Differential sold by aftermarket vendors.
