Some of the best axles on the market! Either the straight or the portal axles are great and I will continue to buy them

They look good and add some ground clearance! They definitely added some weight too. The finish is holding up surprisingly well considering all the rocks they've been drug over! I would recommend putting some kind of light thread lock on the knuckle screw because they seem to rattle out fairly easy but other than that they've been great!

sauber verarbeitet/gefräst und laufen einwandfrei.(PS: manche berichten davon, die Achse abgedreht zu haben...Es ist halt ein kleines Gewinde, daher: Gewalt ist keine LÜsung)bin bisher sehr zufrieden

Looks sweet. Perform great. Assembly would have been a lot easier if there were instructions. I’ve seen some other axle shafts break so I’m making sure i’m easy on mine.

I love these axles. Injora is king of the trx4m upgrades. They look amazing and are butter smooth, however.. after a few runs I've managed to break the stub axle.. it actually broke off while trying to loosen the wheelnut. Possibly overtightened, but anyways, there are no replacement parts available! I will update this review and give 5 stars if I can get a hold of injora for a replacement stub axle..Edit: I have contacted injora and they are sending me a replacement part at no additional cost! Best customer service ever! I am beyond impressed! Excellent quality product, excellent price compared to other brands, and beyond excellent customer service. If I could give more than 5 stars I would!

So these look good and crawl good, however, when I did my first test I immediately saw that now forward is backwards, and vise versa. Not sure how that happens as you can't plug the motor in backwards and you can't install them upside down...sooo have to figure that out. Also with the injora high clearance links it makes the injora axles output shaft angle toward the ground causing driveshaft binding. I don't know what I'm going to have to do to fix it. I figured with all injora parts they'd work together and make a solid rig...but they don't all work together. So use your own judgement.

Injora knocked it out of the park with these. They have a great finish to them good quality and add some great ground clearance. I only wish they would sell these as a single axle so I could put these on my 6x6 build.

Was excited to receive it. No long after I was contemplating putting all this cr*p in a trash bin and shipping it back to Injora. Not a single word of instructions. These also require a flat servo. Also need different suspension links. For the money I expected to have a nice night putting things together not punching the wall in frustration as I guess which screw goes in which hole to find out later I made a mistake and have to undo everything and start over.I am not sure what the problem with Injora is. Why is it so hard to include instructions? Language? Use diagrams. Ikea sell their stuff all over the world and they just use pictures for instructions. This is just negligence and apathy and the best way to never see another dollar from me.

Niente da dire sulla qualità del prodotto che a prima vista è paragonabile a quella dei normali assi Injora che attualmente ho sul mio TRX-4M; purtroppo però questi assi non sono compatibili, il servo può essere montato esclusivamente sdraiato e non la posizione non è compatibile con il telaio originale.

I had the same issues with these axles. Output shaft broke on the axles. And I can't find replacement parts please help injora. They 100% made it right and did it in a timely manner. Great customer service.
