INJORA Stainless Steel Drive Shafts for 1/18 TRX4M Defender Bronco (4M-18)

ALL GOOD

Great looking addition to your crawler

This is such a good upgrade from the stock drive shafts!

Great Product.

Very nice design and finish. Considering their size, they have their own weight.

The go to drive shaft

I broke both of my stock plastic driveshafts and these have been great looks great and works perfectly

a great product

Alles Bestens, schnelle Lieferung, jederzeit gerne nochmal !!!

This is better in most ways because it never fell out once I bought it, it works well and doesn’t rust at all

The tires and drive shafts look awesome but the drive shafts make the truck go so easier you notice it when you crawl

No problem with the product at all nice wight looks great the only issue was that it took a long time for the delivery to arrive

Together with gears, it's a must have upgrade if you're running outdoor.

the front one is jumping a little on full suspension extension and it is super loud

So I left a 2 star review 11 days ago, and since leaving that review Jeff from Injora contacted me and arranged for ModelSport to send out a replacement set at no cost to myself whatsoever!
I’ve fitted the replacement drive shafts and they are perfect! I think the first set I received was just bad luck, everything else I’ve purchased from Injora has been excellent!
Always remember to add a bit of grease to the sliding drive shafts, and always put a drop of oil on the universal joints before installing, and use some kind of thread lock on the pins.
Thanks again to Jeff

I purchased these from a company in the U.K. called ModelSport, they cost a bit more than directly from Injora, but I needed them quicker so had no choice! Initially I thought these were very good, and definitely an upgrade from the original Traxxas ones which actually both sheared after fitting the underdrive gearing, but I am having a problem with the front shaft, the pin keeps working its way out, and when I look at the opposite side of the drive shaft I can see what looks to be a manufacturing error, it looks like the hole for the pin hasn’t been drilled all the way through. ModelSport have asked me to return them for further inspection, but this would mean that I won’t be able to use the car for time it takes for them to sort it out. So I’ll probably just end up purchasing another set, but unsure if to get the same ones again incase I get the same problem! Always use a bit of thread lock on the screws too

Très peu d'utilisation depuis le montage et grosse surprise, les pitons sortent de leurs logements, le risque de pertes et grands pour ceux qui ont un usage intensif de leurs machines. C'est dommage car je vais devoir les retirer pour éviter ce risque par le futur.

Works just as they should. Been running them a while and they are perfect

Works much better than the original. Might be handy to include a couple of extra screws.

Could be smoother movement but seem solid. I installed on a different brand axle housing. Initially they would not fit but I replaced the other diff gears with Injora helicoidal diff gears and they fit perfect now. The helicoidal diff gear set sticks out further from the axle housing and/or the hole is closer to the end of that gear shaft. Either way, nice fit! I hope to see some drive shafts with smoother movement in the future.

Good quality

Looks good and works good but it didn't fit Traxxas metal gear neither Injora spur gear.

Fits injora helicoidal gears.

Looks very good but unfortunately has an incorrectly constructed front shaft. The joints do not line up with each other and create vibrations and binds.

To Look is so nice even the fit. And you dont need to worry about the orginal rubberband…

The pins come off my driveshaft but Injora contacted me and offered me a new driveshaft. Very good. Thank you Injora!!

Took my rig out for the first time in a camping trip. Noticed that one for the pins from the front drive shaft is coming off..it managed to cut though my aluminum skid plate 🤦‍♂️🤷‍♂️

Have 4 batteries through my TRX4m Defender and so far the drive shafts have been flawless. Looks awesome.

Perfect fit, adds weight and looks good.

Perfect fit, adds weight and looks good.

Very high-quality and look amazing, they fix the renowned problem of the o-ring slipping off the stock driveshaft with these upgraded ones. They also feel a lot more sturdy. The only problem is that I wish the screws that came with them were a bit more resistant to the screw stripping out. But overall a great product!

Looks good and gives a smooth ride. Much better then the Traxxas upgraded drive shafts

Die Antriebswellen sind schon sehr ausgereift, allerdings laufen diese nicht ganz in Phase, das ist aber beim Fahren nicht bemerkbar.
