4WD Conversion Kit for CarBlock

This 4WD Conversion Kit is an add-on specifically designed for the CarBlock RC model (1:24 scale, Cyberbrick-compatible). It allows you to upgrade your existing rear-wheel drive CarBlock into a full four-wheel drive machine, offering improved traction and handling.

For this kit, I created a simplified joint design. The goal was to keep the design as accessible and easy to print as possible

Key Features:

• Designed to fit seamlessly with the CarBlock chassis
• Balanced layout for smooth power distribution
• No structural changes to the main chassis required

Important Notes:

• This kit includes only the components needed to add front-wheel drive
• The original rear-wheel drivetrain remains in place

Design Considerations:

Due to tight space on the chassis, a small modification to the gearbox housing was necessary.

Modified gearbox housings are included for:

• The original 1:48 Cyberbrick gearbox
• The G21 1:21 reduction gearbox

For gearbox assembly instructions, please refer to the CarBlock manual.
