INJORA Drive Shaft Steel Front Rear Center Shaft for TRX4M Defender Bronco 1/18 RC Crawler Upgrade,2PCS

Fit great, Good weight, Seem pretty strong. I like the way they look on the truck

The shafts look great and fit perfectly. The issue is that the pins that holds the universal joint together slids out of the shafts. I am able to slide them back in, if I catch it in time. But they will be useless when one falls out and I can't find it.Injora makes great parts, but these are not up to their standards. I only ran 2 battery packs on them. I do have the Meus two speed transmission, but it's usually in low gear crawling. They should not be failing so soon.Injora customer service did respond to me, and send out a different set.I would recommend a different set of dive shafts.

These are great axels. Add weight over original as well. I love the fact that you don’t have to deal with the o-rings anymore. I have not had the issues with the pins coming loose yet (only 1 1/2 packs run) hopefully they hold up well.

Great fit for the trx4m, these perform far better than the factory axles with far less bind at full suspension articulation. Great value for the performance gain. These add some weight down low as well for added crawling performance. Easy to install, took less than 30 minutes.

These driveshafts look good and perform well. I have purchased several sets for various builds. However, they may not bolt up with other aftermarket products. I purchased a MEUS axle set for front and rear and these Injora driveshafts did not bolt up. I had to grind and file down the axle pins on the MEUS axles to get the Injora driveshafts to finally seat onto the axle pins. It was a delicate operation in which a lot can go wrong. I got lucky!Once mounted up they have worked well so far.

Fit and finish is perfect as expected from Injora. They seem plenty durable, no abnormal play or anything like that. They slide good as well.

Perfect fit with Injora transmission. Adds a bit of weight to bottom of truck. Semi easy to install needs a bit of disassembly of truck, but not too bad. Much better price than OEM upgrades I don't see these breaking with a 180 motor. Smooth driveline joints definitely a performance upgrade. Just be sure to line them up the proper way, if they are off in the timing they are grindy. You need to line up the “ears” of the driveshafts.

Well I had high hopes for this set, sadly that is not the case. Just like the set I bought for my SCX24, the pins at the universal joint are falling out on the front and the rear. I installed these a week ago and was going to take it outside today for the first time and noticed that the pins were falling out on this set as well. These had such high reviews that I took the chance and now that is money wasted. I am ordering a set of MEUS driveshafts. If the OGRC were not so far out on shipping I would buy them like I did for a couple other of my builds. Not impressed with INJORA's quality on these.
