Discover our range of Technic gears, ideal for building smooth, reliable mechanical functions in your custom Lego creations. This category includes a variety of gear sizes and tooth counts, allowing you to fine-tune speed, torque, and direction in your builds. Whether you are designing complex gearboxes, motorized vehicles, or compact mechanisms, these parts help you achieve precise motion control. Combine different gear types to experiment with gear ratios, improve performance, and bring advanced engineering concepts to life in your Technic and custom models.
Explore a wide selection of Technic gears designed to support everything from simple rotations to highly advanced mechanisms. Within this category, you will find common gear types such as spur gears, double bevel gears, and worm gears, as well as more specialized options for fine-tuned mechanical builds. By mixing different diameters and tooth counts, you can easily create custom gear trains that match the exact speed and power requirements of your project.
These gears are ideal for builders who want to add realistic motion and control to their models. Use them to transmit power between axles, redirect rotation, or synchronize multiple moving functions in a compact space. They are especially useful in Technic-style constructions, custom Lego machinery, robotics projects, and experimental prototypes where durability and precision are important.
Many builders rely on Technic gears to build gearboxes, differentials, steering systems, and lifting mechanisms. Smaller gears are perfect for compact assemblies and high-speed applications, while larger gears are better suited for high-torque tasks such as lifting arms, driving tracks, or powering heavy-duty features. By combining several gears, you can create reductions or overdrives that dramatically change how your model behaves.
Technic gears also provide a hands-on way to explore engineering principles. Adjusting gear ratios can demonstrate how mechanical advantage works, making these parts a popular choice for educational builds and STEM activities. Whether you are refining an existing model or starting a new custom design, the flexibility of this gear selection gives you the freedom to experiment and improve your mechanisms step by step.
Browse the full range to find the tooth counts, profiles, and connection styles that best match your building style. Pair your gears with compatible axles, liftarms, and connectors to create strong, stable assemblies that stand up to repeated use. With the right combination of Technic gears, you can transform static builds into dynamic models with smooth, controlled, and reliable motion.
