The components are indeed strong and built very well. The package however does't include any hint or paper on assembly and installation, which is *not* straightforward for any car. The differential hub pieces are to short in the diff connection, which can make them "float" too close to the gearbox and cause unnecessary wear and even cause internal damage. The other side (wheel carrier) locking mechanism requires great attention during assembly, because its never clear enough if the pins are really locked by the provided screws. Loose one of those pins and the entire system is history, because they are specifically built with a small carving in the middle which is supposed to be in direct contact with the screw and properly locked. I would look for other options if a strong driveshaft was really necessary (i.e. you have a really powerful motor and a 12V lipo).
