Overview
The Kyosho Spur Gear (48P, 69T) (UB050-69) transfers power from the pinion to the transmission and sets the final drive ratio 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.
Gearing is 69T at 48 pitch. 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.
