Overview
The Kyosho Battery Weight (35g, Brass, RB7.5) (UBW004) adds ballast low in the chassis for the Ultima RB7.5 1/10 scale platform. It is supplied as a genuine Kyosho service part, so the dimensions, material and mounting match the component fitted at the factory.
Finish is brass. Order against the part number rather than by appearance: Kyosho and other manufacturers reuse similar shapes across chassis generations, and the part number is what ties this component to the right parts diagram. Check how many the car takes at this position before ordering.
