Injora TRX4 Clone Axle Deep Dive

Hi guys,

The highlights:
- Guts of axles are directly transferable, Injora diff assembly is a hair tight in Traxxas axle housing but I think it would run in (use your own discretion)
- Traxxas T-lock flipper works with Injora but Injora was tight in Traxxas and I didn't feel the need to force it. Visually, I don't see why it wouldn't work. Attempt at your own risk. I probably should check this because of the cost of those Traxxas T-lock cables ($18 Cdn), stay tuned
- Rear axle portal housings do not match up
- Front axle portals work fine in either
- Rear axle portal input shaft outer bearing in Injora is 5x10x4, not 4x10x4 (not sure about the front, didn't notice at the time I had it apart) This is not an issue if you are swapping guts but is an issue if you are swapping ONLY the portal input gear. A Traxxas bearing set will not be 100% compatible, you'll need (2) 4x10x4mm bearings
- Traxxas drive shaft does not fit Injora input shaft. Hole is just a hair too close to the axle

These axles are pretty darn good but there are a couple of problems. To me, that means you have to look at the $$$ to see if they are indeed a good deal. Because I can get a set of TRX4 axles removed from a brand new truck from JRC for about $50 Cdn more there's a pretty good bench mark. To me, if you have to put any parts into these the value becomes dodgy right away, so you have to be willing and able to run them the way they are. The only real problem is the pin hole in the pinion input shaft which needs to be modded to fit a TRX4 drive shaft. Pretty minor fix in my book.

Now we need to see if they are durable, because genuine TRX4 axles are gorilla strong. Stay tuned.
