Technic, Gear Differential Housing

Build Drivetrains That Truly Perform

The Technic Gear Differential Housing (65414) is a cornerstone component for any builder serious about creating realistic and functional vehicles. This specialized housing is engineered to enclose a set of gears, forming a differential. This mechanism is crucial as it allows the outer drive wheel to rotate faster than the inner drive wheel during a turn, providing smoother cornering, improved stability, and a more authentic driving experience for your models.

Whether you're designing a high-speed race car, a powerful off-road truck, or a complex industrial machine, this housing is the key to unlocking advanced mechanical functions. It serves as the rugged foundation for some of the most intricate parts of your build, connecting directly to your model's powertrain and chassis.
