SWorkz S35-3/GT-series gearbox set
Coming from SWorkz and made for their S35-3 series off-road and GT cars is an updated gearbox set. It now utilises 5x13x4mm ball bearings which is especially helpful for the GT cars as the ball races can handle higher RPM while creating less temperature all while retaining a smooth and efficient drivetrain. The gearbox fits all 35-3 series and GT cars.
