Much better than the factory Diff fits and works great in my BN16 Hyper Go

Holding strong, blew up the stock rear within 2 charges, then got the 3s battery and it’s holding strong, shredded the rear pinion and no damage to the ring gear at all

Definitely an upgrade from the original in the H16BM.However the screws of mine are quite rounded out, obviously over torqued at the factory; which is a bit disappointing given the price!This really should be a standard part instead of the original which broke with just the standard 2S batteries (see disassembled pic).

My differential came with an improperly machined outdrive; look at the picture (first photo is this one with a small dimple on a flat surface, the second photo is the correct part from the previous differential and is fully concave), but basically it was out of tolerance by about 1-2mm which caused it to not fit into the rear drive assembly.UPDATE:Ordered a second one because I saw the cups in another reviewer's photo to be good. Second arrived and the cups are good, but one of the casing screws are stripped. Going to return both. Not sure if I'll order again. The diffs themselves feel good, but seems like there isn't much quality control with these.

So far so great. Stock rear diff lasted about 4 packs. Front maybe 7. These upgraded units seem to be of much better quality. I'm 4 packs into the new rear. No failure. Only 1 into the front but I don't anticipate any issues for a while.

I was about to send my rc truck back cuz it was clicking and had no power. I truly thought the motor was bad, and I was unsuccessful online looking for answers. Tearing the thing apart seemed like a lot to get into, but I tried it. It wasn't that bad. Then I narrowed it down to this thing. I was glad when I found it was not the motor making the noise, and when I figured out it was this, then I found things out about it. So, the car is about 2wks old. I didn't mind doing the work and installing a 20$ part. Some folks might. It was a good many small screws in various sizes. You could always send the thing back and get another, but I think this part may just break again, and I'd be in the exact same boat as I am now. So far, I'm glad I chose this route. It fit right in, and runs like new again. Now to the tires, cuz there ain't much left!

The original diffs blew super fast, this upgrade has kept me going for a year or so now! Definitely worth the upgrade to jeep your car going!

Good replacement parts, pretty easy install if you know what you're doing. I sheered the screws on the OEM installed parts, the gears are very strong, but the screws holding the halves together can easily be sheered if you accelerate too hard on carpet over and over and over. But the part works great. Does what it has to and it's nice it's on Amazon rather than some random Chinese website!
