5-Pack Black Steel Metal 32P 5mm Pinion Motor Gear Sets 17T 18T 19T 20T 21T Compatible with HPI Kyosho Losi Axial Tamiya 1/8 1/10 RC Car Monster Truck Buggy

The media could not be loaded. These were a direct fit for my Hobbywing QuicRun setup for ARRMA Gorgon. The gears come in multiple varieties so you can adjust to your driving style. I have been running the 15t in the Gorgon, but have tried the 17t, 14t & 13t. The gears seem to hold up well, have been running them for several months. I would recommend this pack because you can really get your setup dialed in with the multiple options. These do come with the grub screws, just make sure to loctite them in when installing it changing gears. They are great value for what they are and they function as well expected.

THIS IS 5MM BORE so you will want to be certain your shaft is 5MM.I bought the Team Associated Rival MT10 a few months ago. It was the version with the brushed motor. It is the cheapest way you can by that truck. I planned to buy it and then re-build the electronics to my desire with better-than-stock versions. Boy, am I happy with how this turned out! I added the Hobbywing 10BL120 ESC and Motor combo. That combo came with a 5mm shaft so I couldn't use the existing pinion as it was the smaller hole. So, I saw this and decided I would go for it. It was a breeze ( on my truck ) to add the 17-tooth pinion on my motor, get it meshed and haul booty! The og pinion was a 12 tooth so I am getting a lot more turns out of the spur gear now and that is translating to some serious speeds from my rig. I will, in time, gain the courage to try the bigger ones and will update when I do.I have had zero failures or problems, they are accurately marked and seem to be well-made. Of course, time will tell the rest of the story. It is VERY nice to have all of these choices in one bag too! There is also a hex tool included which I used to tighten the grub screw.

These are heavy duty motor gears, fit my brushless motor perfectly and provide brutal force. Come with five sizes to change the gear ratio for more fun. Highly recommended.

The media could not be loaded. As you can see they are not all labeled. I would’ve thought that they would have been new in a package but instead I got 5 gears,3 of them you can read what they say, but the others you can’t. I would definitely say that, these are not a new pinion gears. They look like they have been somewhat worn, This is not ideal. They don’t look chewed up but they don’t seemed to be new neither. I’ll give them 2 stars because 3 of them looked ok, But the others you really couldn’t read what’s on them. Also they we’re packed in a vacuum, sealed little bag with no receipt or description on what was in the little bag.
