This Differential Upgrade Kit is an add-on specifically designed for the CarBlock RC model (1:24 scale, Cyberbrick-compatible). It adds working front and rear differentials to the chassis, enhancing realism. The design is based on the official Cyberbrick Truck differential but has been slightly modified to fit the CarBlock.

You can use the Bambu Lab Plastic Differential Gear Kit for stronger low-friction nylon parts. Only the gears are used; the included metal pins are not required. Alternatively, you can 3D print all required parts, including the 4 pinions and 2 main gears. The printed version works well, though it may wear slightly faster than Teflon.

To be honest, adding the differentials does introduce some additional resistance, which may slightly affect drivetrain efficiency but it definitely feels more authentic, and is way cooler!
