Yokomo Z2-503GHCA Aluminum gear diff case cap (Hard coat) for YZ-2/YD-2 series  [Z2-503GHCA]

That's an aluminum differential instance restriction the gear differential based in the YZ group of off road automobiles and the YD-2 wide range of drift cars. It gives greater heat dissipation efficiency than standard resin items, as well as by curbing the temperature enhance the interior oil, you can actually keep viscosity changes towards cheapest which help driving faculties. In addition, improved precision improves rotational effectiveness and stops oil leakages, to be able to expand the upkeep level of differential.
