Same as chrome ones.** A: Yes they the same, I have both sets so, I can confirm that they're the same **Q: Whould these fit fms fcx or furitek caymen? Thanks** A: They are for 1:18 scale crawlers, but they're only a few bucks, so try em out. You could probably cross reference sizes though to find out for sure. I know the hole to attach the shaft is a d-shaped hole. **Q: Any idea if these will work with the K10 High Trail?** A: I use them on my K10 Monster Truck build with 59mm INJORA shocks. It's at their limit, but functional. I think INJORA just came out with a stainless steel version, specifically for the K10, on their website. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome driveshafts *by M***E on January 12, 2026* Heavy duty, seem to work better than the stock plastic ones.
