Way better than stock!
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!

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.

Awesome driveshafts
Heavy duty, seem to work better than the stock plastic ones. Recommend using lock tight on the screw, one of mine fell out. They did come with spare screws. I have not had an issue with the pins falling out.
