Solid upgrade from Injora
This is a great upgrade for the stock TRX4M - plastic to metal conversion. It's a no brainer. They're metal so they're a ton stronger than the stock plastic ones. They look way cooler than the stock ones as well. And they're heavier so it helps keep the CoG low. They're also from Injora - one of the most reputable brands in the business. Easy enough to assemble and came with all necessary hardware - a couple of set screws. Make sure when you install them, you install them "in-phase". Google that and you'll see what I mean. Installing this way will help reduce torque twist.

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.

Awesome upgrade!
Awesome little shafts for the cost! They definitely make the bottom side look a lot better and add a lot of strength to the drive line. Easy to install and not super heavy to turn

Screws
Screws are crap one time use item. But you got room to drill and thread a little thicker bolt in there.

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.
