This is a direct upgrade for the Turnigy Trooper Nitro 4X4 SCT 1/10 scale. On the manual it's suppose to be part number 32924 but it doesn not come with all the screws. Dont worry as you don't really have to replace these screws that the ones in there are M3 thread which is what these mounts take. These mounts also allow the installation of the central disk brakes for both front and back which is standard for 1/8 scale but only optional for the Trooper 1/10 scale. You don't have to get it so don't bother wasting your money. Do I recommend it? HELL YEAH.
