This Robinson Racing Products pinion gear features 17 teeth cut to 48 pitch, making it a direct-fit replacement for a wide range of 1/10 and 1/16 scale electric RC vehicles. The hard nickel plating over the metal construction provides increased surface hardness for improved wear resistance compared to standard uncoated pinions.
