Tekno RC hardened steel diff case
Coming from Tekno RC and made for their line of off-road vehicles is a hardened steel diff case. CNC machined from steel and hardened, this diff case handles the extreme conditions found when pushing the vehicles to the limit. Although a steel diff case is perfectly suited for the MT410 or ET48 with a huge motor or 6S battery, it can also be used as a tuning option to help reduce wheel spin when racing the ET48, EB48, NT48, NB48 or SCT410 kits. The hardened steel diff case is a direct replacement for composite diff case and can be used in the front, centre or rear differentials.
