Strengthen the driveline of your Kyosho V-One R4 touring car with the Kyosho VZ403HE Hard Diff Case Set. This genuine Kyosho part uses a harder material than the standard case, giving the differential a more rigid housing that holds its shape under the high loads of nitro on-road racing.

A stiffer case keeps the internal gears aligned, which means more consistent diff action, less wear, and fewer surprises late in a long run. It is an easy reliability upgrade and a smart spare to keep in the pit box.
