Injora came through
I bought this pair of axles to spruce up my TRX4M and it got shipped to a different house. They sent a replacement and I’m pleased. They add nice width to the rig and have a great turning radius. As always make sure all your screws are tight before installing but I’m very pleased. When I turn my rig into 4ws I’ll buy another set.

High quality axles
Awesome quality for some little axles! Adds lots of weight down low and raises ground clearance. Definitely helped traction Great product to improve performance in these little crawlers. Easy to install and fits perfect. Definitely one of the more expensive but worth it upgrades if your into the hobby

Love em.
These are hands down the best axles I’ve ever put on a trx4m. I love the portals, just that little extra ground clearance changes the car immensely, wish that the individual replacement parts were obtainable via Amazon

Great little axles!
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!

Great product but your shipping department is messing up your reputation by offing returned goods!!!
Love these but I would have loved them more if they were the color I ordered and weren't returns that you just offer on the next guy! Your shipping dept. Is making some shifty moves you need to look into!!!

Top Quality, Can't go wrong
I did a custom build using a meus frame and all the rest is Injora, i buy Alot of injora products because of the exact Quality every time, this review is about the Portal Axles, the Quality is top notch using all steel gears, sealed bearing units, hardened axles. They bolt right up to your chassis with the included hardware, the instructions are vague but installation is straight forward. I have bought 4 sets of front and rear axles and have never had one issue. If you do a build, all of the running gear components are unstoppable, the only downside when ordering is they come directly from their warehouse in China and take a little longer to get delivered, they do now have a new USA warehouse on the east coast that gets your parts to you a bit faster, but not by much from my experience, I am in Washington State on the west coast, But still worth the wait.

Awesome!!! Doesn’t fit factory Bronco/Defender frame
These are rock solid and takes my Bronco TRX4M to the next level! Nice amount of weight helping with the low center of gravity. They had some grease in the differential, just need to add some in the portal ends, so have some grease handy before installing. The lay down servo mount / front axle setup is not designed for factory frame, so order the universal carbon fiber frame with battery mount. If you choose to install on the factory frame, you’ll have less than 1cm of compression on the shocks with a high clearance setup for the TRX4M Bronco/Defender.

Injora has made this right. Broke within the first hour of use and it's first roll over.
The screw part for the axle snapped right off I just bought these installed last night and broke today after a hour of use and it's first roll over. I absolutely loved the look of these I have bought so much injora products but I'm so unhappy right now all parts on this except the body are injora Injora contacted me and sent a replacement part which took about a week very happy.

Amazing!!
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!
