1:14 2-Speed Shift Gearbox Compact, gearbox

A 2-speed transmission changes the character of a scale truck build, and this 1:14 Compact gearbox brings that function into a neatly machined aluminium unit. The compact housing gives the drivetrain a technical focal point while keeping the installation footprint suited to tighter chassis layouts. The assembly data points to use with the original Tamiya motor, so the gearbox is built around a clearly defined motor fitment rather than a vague universal claim. The housing uses a front circular mounting face with multiple screw points, creating a structured base for fastening into the model. A shaft coupling is secured with a 3 x 3 mm set screw, and the instructions specify gel-type thread lock on the marked fastening point for a firm mechanical connection. The motor plate is attached with 3 x 8 mm screws, and an assembly dimension of 11 is shown in the motor fitting step. An optional servo mount for the 2-speed function is referenced in the documentation. In a 1:14 road truck or working vehicle project, this gearbox suits builders who want the drivetrain to feel more like a scaled mechanical system rather than a simple direct drive layout. It also fits detailed upgrade builds where aluminium parts, visible fastening points and a dedicated shifting mechanism add workshop character to the chassis.
