This 6pcs set is an RC-scale replacement gear package intended for the rear gearbox area of compatible TRAXXAS 1/10 2WD models. It uses carbon steel for the main spur and pinion components and is specified to transmit drive torque from the motor into the drivetrain. The kit lists a 56T spur and a 15T pinion as the core gears, with the pinion corresponding to TRX4015T where noted.
Technically, the parts are service items for gearbox maintenance or gear ratio swaps. They are suitable when replacing worn teeth or matching gear ratios for tuning; attention to mesh, shaft alignment, and the supplied screw/washer hardware is necessary to ensure correct operation.
