This will be installed in a WLToys 12428. Gears aren't that smooth, but I'm guessing they'll wear in. Only other issue is the hole for the axles go through the hole gear so the retaining screw passes right through. The original gear had a smaller hole for where the retaining screw went. I have put a tiny washer under the screw head, but it isn't great. With not having the extra material at the end of the gear, you lose the slight gap between the gear and what ever the axle is passing through (the larger gear in the case of my pictures). Sorry the pictures are blurry, but I tried to show the original plastic gears, the metal gears with washer under the screw head and the gears without the wash under the screw head. I'm suspecting this will work okay, but instead of having a fully open differential, it will be stiffer and a bit more like a locked differential. This will be good in sand and dirt, but not so great on pavement.

🇫🇷 Order, received after a couaque (I had received a metal part which I don't know the utility and an ink cartridge no name for I don't know which printer)... This time it's the one. After I did not test the compatibility with the Wltoys 144001, but the parts sound of correct quality...

🇫🇷 Commande, reçu après un couaque (j'avais reçu une pièce métallique don j'ignore l'utilité et un cartouche d'encre no name pour je ne sais quelle imprimante)... Cette fois c'est la bonne. Après je n'ai pas testé la compatibilité avec la Wltoys 144001, mais les pièces son de qualités correct...

A very good replacement for the plastic gears in my WLtoys 12428 which were worn out.They fit well and now my buggy is running again. The gears I received were silver chrome and not the ones shown in the sellers photo.

i installed these on my 12428, they were a bit tight fitting so i removed 1 of the 2 shims in the differential and it ran smoother. I put some grease in them and have been running it since. awsome gears for a great price, i reccomend these for anyone running higher power than stock.

Хорошие шестеренки. Тяжелые, твердый металл - напильник с трудом точит. Красивое серебристое покрытие.
