Hey RC enthusiasts! Give your WLtoys buggy or touring car a serious durability upgrade with this set of 4 steel CVD drive shafts. If you're tired of stock plastic drive cups or dogbones popping out or wearing down, these metal replacements are the answer. They're designed as a direct fit for popular WLtoys models like the 144001 (1/14 scale) and the 124016, 124017, 124018, 124019 (1/12 scale). Made from tough steel, they're way stronger and more durable than the original parts, which means better power transfer from your motor to the wheels and less chance of breaking during a hard crash or big jump. They're also removable and replaceable, making maintenance a breeze. They come in black and are precision-engineered for a smooth fit. A simple swap that can really improve the reliability and performance of your RC car. Just make sure your model is listed before you buy!
