Its clever internal design allows the two wheels on an axle to rotate at different speeds, which is essential for smooth and stable cornering. When a car turns, the outside wheel has to travel a longer distance than the inside wheel—without a differential, the wheels would skip and lose traction. This part is the solution, making it a cornerstone of advanced Technic building.\u003c\/p\u003e  \u003ch3\u003eApplications for Smooth Cornering\u003c\/h3\u003e \u003cp\u003eThis differential is a must-have for the drivetrain of any wheeled creation, from supercars to heavy-duty trucks.\u003c\/p\u003e \u003cul\u003e     \u003cli\u003e\n\u003cstrong\u003eRealistic Drivetrains:\u003c\/strong\u003e Install it on the drive axle of your car or truck to allow for smooth turning, just like a real vehicle.

[1, 11] It replaced an older, bulkier differential design from 1980 that used different gearing. [2] This newer, more compact and versatile design, with its 24 and 16-tooth gear options, quickly became the standard for nearly all high-performance LEGO Technic vehicles for decades.
