After burning through the stock drive shafts, then replacing them with a few times with the brand plastic parts, I had enough. 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!
