In my experience, the YIKONG YK4107 RC Car Original Parts Girder 21012 is quite durable. The nylon material has good toughness and a little flexibility, so it can absorb impacts better than some stiffer materials. For normal driving, trail running, or light crawling, the YIKONG YK4107 RC Car Original Parts Girder 21012 holds up very well. Unless you’re doing aggressive bashing or experience a very hard crash, it should provide reliable performance and a long service life.
