Not happy. Gears were possibly machined incorrectly. Once installed , gear set does not turn . Removed and added provided shims, still won’t turn. Removed to check diff housing for deformation, fine. Reinstalled with grease but still won’t turn. I had ordered two sets of, one for me and one for my son. Neither set works correctly

I’m running these in meus portal axles, and the gears mesh up better than the originals that came in the axles.

The only thing i have to complain but i dont really mind it much is that at full turn they do bind up a bit (actually its just the front gears) not sure what the case may be i checked everything used the shimes and i got it to where im happy but just keep in mind they will bind just a hair some way or another but it’s hardly noticeable

Rear underdrive gears went in fine with minimal gear noise and spins freely. Front overdrive was terrible. Ring gear was out of round and no amount of adjustment could get rid of the clicking and binding. Had to put the stock gears back in because I couldn’t get it drivable with these.EDIT: customer service sent me a new front ring and pinion and it’s on point! I have over/underdrive gears from Injora in my 1/10 crawlers and they were all great. This was the first time I’ve had an issue and it got resolved quickly.

The gears fit in the stock trx4m axels but they are not smooth at all I’d stick with the metal stock axels gears they feel super smooth

i received this set and installed it only to find that the underdrive set had a defect and would bind up the whole driveline to the point that i had to put the stock gears back in, the front works flawlessly though so i might just be unlucky.

Like other reviews, the rear underdrive gears don’t want to mesh with or without the provided shims. The front overdrive gears work though, so there is a minimal improvement over the stock ratios.*I have since upgraded to Injora Diamond axles and the front and rear gears work great.I think it should be mentioned in the product description that the gears may not work on stock axles, seems to be common.

This gear set is absolute trash, gears are obviously out of round. Gear mesh is atrocious and the gears are unusable.
