Theo are just perfekt
These are my go to axles for a crawler build. I have them on two rigs currently. They are heavy enough that the extra clearance isn't a problem. One of my rigs exceeds 1000 grams and these axles have zero issues getting the truck around.
I have the brushless system from traxxas, and when I installed these, it seemed to make it not able to crawl as slow as it did before the axles, and it is more jumpy when trying to crawl over things slow, like the stock motor does.
Any ideas to help this?
Other than that, I love these axles
Love them all. Injora upgrades are some of the finest. My trx4m high trail is 95% injora. It looks nice too.
Hello I ordered those portal axle 3 weeks from now and they were perfect till the left one broke out of nowhere I can’t put the wheel back on as you can see. They never been in the water or anything.
So I asked a refund or just the part that is broken but for now, no response it’s been 2 days and I sent photos and videos in the mail.
So I recommend them but its a must to put spare parts that you could buy separately Injora it would be great thank you. 👍
These axles look great and have very little slop. I did end up breaking one of the shafts but the company did get in contact with me and the replacement parts are on the way for super cheap.
Good unit
I truly love every Injora part I've ever used.
They are way better than I thought they would be
Good
Absolutely love these portal axles
work great and are really durable!
Since they were out injora pumped up the quality of them. They have so much clearence!
There are no better portals for the TRX4M than these...
Favorite axles i run. I have a set on my trx4m bronco and thinking about my next build maybe a 4 wheel steer on portals????
Awesome set of axels everything works as it should all links fit good and bolts go right in
super smooth great turning circle and awesome gear reduction Allround perfect couldn't be happier
I also just got these and mine snapped very easily. I like Injora products they are on all my builds. Wheels,tires,parts but this is a bit disappointing as I never even got a chance to use them before it broke so easilly. Would like to have replacement parts for them but seem can not reach them easilly they never reply to my emails recently
I have these portals fitted with a 9% od in the front and a furitek cedar combo using the
injora trans and 24.4:1 gears and it has been awesome so far.
Quality can use some improvement.
Portal shaft sheared off on a small tumble.
With this model being new, there aren’t replacement parts yet.
Aside from that, they look great and provide plenty of clearance.
Do they come pre greased?
Is it compatible with stock axle injora overdrive underdrive gears
Yes.
Would this fit my hpi venture18cc competition crawler?
No.
Will this work on a red at ascent 18
Not compatible.
What is the steering angle on these axles? I am trying to decide between these, and the ones from meus, but Meus' only have a 35 degree steering angle
I think the steering angle is similar to the stock TRX4M axle (around 40–45°).
Will These fit with the tarantula chassis
I think it is not compatible.
When I push the throttle backwards to make the car move forwards, the car goes in the opposite direction than when it went before I got the new axle.
Yes, this is quite common on portal axles. Please reverse the motor plug or reverse the throttle on the transmitter.
What kind of grease is recommended for the gears. I see you sell grease but description says special formula for 1/10 rc cars. Just want to make sure I put the correct grease in. Thanks
We also sell grease for 1/18 & 1/24 RC cars: https://www.injora.com/products/injora-diff-grease-for-1-18-1-24-rc-cars-19g
Dose this work for the trx 4m hight trail
Yes.
Will the portal axles work with the stock trx4m servo
Yes.
