F104 Spur Gear Adapter, RC chassis accessory

The F104 Spur Gear Adapter is a drivetrain accessory for selected Formula chassis that expands gearing options by allowing touring car spur gears to mount on F103 and F104 platforms. That added compatibility supports finer ratio selection, so a setup can be matched more closely to motor choice and driving area when tuning a model for different running conditions. The adapter is supplied as 1 spur gear adapter and works with a defined group of chassis that includes F104PRO II, F104Ver.II PRO, F104W, F104, F103GT, TRF103, TRF102 and TRF101. Compatible spur gears listed for this part are 50978, 51056, 51215, 53857, 54055 and 54227. The installation layout places the adapter on the shaft before the spur gear, where it acts as the mounting interface for the gear assembly. Depending on the transmission used, the spacer may also allow an increase in the number of differential balls. In workshop use, this part suits rebuilds, ratio changes and chassis-specific drivetrain updates where a broader spur gear selection is needed. It also fits maintenance sessions that replace worn transmission parts while keeping an existing Formula chassis in active running trim.
