INJORA Steel D-Shaped Hole Drive Shaft for 1/18 TRX4M Defender Bronco

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.

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.

Perfect fit

Great replacement on a small Bronco. pretty easy to install and nice and solid compared to the plastic ones.

These hold up far better then stock parts.

Great fit, but pins can fall out. I put electrical tape over the U joint, works fine.

Fit perfect. Work as well as OEM parts.

I used these in two of my TRX4M vehicles. They work as they should.

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.

Great upgrade for the trx4m

Excellent parfait 👍

Injora is great for the price! Trx4m bronco
