Toughbox Mini Classic 12.75:1

The most reliable tried, and true gearbox for FIRST Robotics Competition teams. This gearbox has been proven on the field of competition for ten years.

The Toughbox Mini uses the same interior parts as our bulletproof Toughbox. Shipped in an unassembled kit of parts, you save. Hardware is included with the gearbox for attaching two NEO, or CIM style motors.

All AndyMark gearboxes require grease for proper operation and long life. We suggest using our red tacky grease, am-2768. We also encourage that the user powers the gearbox continuously for 30 minutes without grease to allow the gear teeth to wear in. While we do design with short run times in mind, this 'run in' period for smooth gearbox operation, is recommended. Once this is completed, thoroughly grease the gear teeth periodically to ensure smooth operation.
