INJORA Steel Sealed Bearing Kit for TRX4M 1/18 RC Crawler Upgrade Parts, 22PCS

These are a great upgrade for your TRX-4M. They work and fit as they should they are cheaper than the Traxxas set. I will be upgrading all my TRX-4M with these bearings.

Works phenomenal, good upgrade

This improved the drivetrain smoothness 10x compared to stock brass bushings. I honestly didn't think these would make as much of a difference as they did, very smooth. I would assume this would just about double my battery life if the truck has been working this hard for over a year just to overcome bushing friction/resistance. This is probably the most cost-effective improvement you can make to your TRX-4M. Bearings fit perfect, and there was one for every single bushing on the truck.

Injora products are the best. Perfect fit and easy to install.

Not sure the tolerance of these and I cannot tell the difference between these and the Traxxas branded set, so I will most likely get these again in the future. They make a 100% difference over the stock sealed bearings that come with the TRX-4M. Its a no brainer replacement, although I am stacking up with transmission bearings for some reason, we need a set with or without the transmission bearings, every set of gears comes with them anyway. If you get this set and expect to replace them all, be prepared to disassemble the entire car, literally. I've been replacing as I go, but I noticed that there are some that are more labor intensive than others. The front axle bearings, in particular. It took me some time to strip down, clean and reassemble the entire front end to replace these. The transmission bearings took some time too, so I saved those for when I rebuilt the transmission, they of course went in easily and worked very well over the stock bearings. I would and will buy these again and would recommend them to others, 100%

Works just as good if not even better than the ones I bought from Traxxas at aover double the price that they would charge Awesome bearings👍🏽

Pretty good, nicely packaged and bearings are smooth. Wish they would label each baggy with the size of the bearings, but it's not a big deal. Just want to note that this WILL NOT eliminate torque twist on the TRX4M. Did not notice much difference at all after installing all the bearings. The mini crawler just sucks lol should not have to upgrade so much on it.

I put these bearings in my trx4m k10 high trail...all bearings were there and they all fit nicely...they replace every bushing that comes on the truck including the transmission bushings....took me about an hour for complete installation...overall the truck is noticeably quieter and smoother when driving..especially for the price this is a homerun...get some
