Sequential Dual-Clutch Gearbox MOC-14405

This ZITIANYOUBUILD set contains 713 plastic building bricks that form a functional eight-speed sequential dual-clutch gearbox. It is designed for adult builders and advanced hobbyists who enjoy mechanical engineering models and Technic-style construction challenges.

Suited for builders who want a complex gearbox

The set suits collectors of custom MOC designs and educators demonstrating transmission principles. It is not for buyers who want a motorised driving model, a vehicle chassis or electronic components. Younger children will find the build too intricate without adult assistance.

Check compatibility before ordering

Verify that your existing brick collection uses the same clutch dimensions as major brands for a tight fit. Ensure you have a device to view the supplied PDF instructions, as no printed manual is included. Confirm the 713-piece count matches your project requirements.

Questions about this item

Do I need any LEGO bricks already to build the 713-part gearbox?

No, the set includes all 713 pieces needed to complete the sequential dual-clutch gearbox; no extra bricks are required.

Will the finished 8-speed gearbox mesh with older LEGO Technic axles I already own?

Yes, the parts are 100% compatible with LEGO, so the gearbox shafts and connectors fit standard Technic axles and gears.

How can I confirm the sequential dual-clutch mechanism shifts through all 8 speeds correctly after assembly?

Rotate the input shaft by hand and watch the output shaft; each click of the selector should advance the gear ratio cleanly through all eight positions.
