SCX24 crawler enthusiasts, ready for more power and torque? This RCAWD upgrade kit replaces your stock 030 motor with a much larger and more powerful 180-size, 51-turn carbon brushed motor. Carbon brushes mean it runs cooler and lasts longer than standard metal brushes. The kit isn't just the motor – it also includes a complete aluminum transmission (center gear housing) assembled with durable steel gears. This red aluminum housing is CNC machined for precise fit and long life. It's designed to fit various Axial SCX24 models like the AXI90081, AXI00001, AXI00002, and others (check the full list). Note: installation requires removing the original receiver holder. This combo gives your tiny crawler significantly more low-speed control and crawling power to tackle tougher obstacles. A fantastic performance upgrade for serious mini-crawler fans!
