These high quality metal replacements work perfectly on both Bronco and Defender TRX-4, and have stood up to rigorous field testing (kid tested haha). There are lots of these to choose from, but after research I grabbed these. Good price and worked great! I will warn, they do make the machines drive a little less smooth, especially at full tire turn, but it's hardly noticeable and way better than the alternative. These things are built for off road anyways! Review: Top but with a quirck - Can't argue with the build quality! Definitely a must, especially if upgrading for a brusheless motor, as the stock transmission axles will break. However, be aware that these will introduce some wheel slack. ## Features - Stainless steel materials construction, not easy to rust - Enhanced structure design for long-life durability - Scale Joint and spline diameter size for realistic appearance - D-Shaped and rounded rectangle holes desgin offer tighter connection to transmission and axles - Note: Designed for 1/18 TRX4M Defender Bronco.

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 ### ⭐⭐⭐⭐⭐ Way better than stock! *by J***W on 26 June 2025* After burning through the stock drive shafts, then replacing them with a few times with the brand plastic parts, I had enough.
