Must of got a bad set they’ve run really rough in my LC. 80 stock gears were smoother obviously not stronger. This would be my fourth differential gear I bought and seem to have problems with my second one and noticed that only one of them came with a bearing on the pinion don’t ever have problems with injora

Fitted on my 1/18 K10 Cheyenne, very easy job to do, these replaced the stock plastic gears.Can recommend them.

Installed the 20t overdrive gear into my fcx24 power wagon and everything fit good and after I got it back together it ran fine for about 30 seconds and jammed up. Took it back apart and the gears were binding up and not turning free. Replaced with my stock one and everything is smooth and not binding up. Bought two of them so going try the other one in my fcx24 K5 and see if it does the same.

Leider etwas enttäuschend. Klar es funktioniert, aber die Differentiale laufen jetzt rau und schwergängig. Die originalen Plastik-Teile liefen viel, viel weicher.Schade Injora, ansonsten sind die Teile bisher immer Top gewesen!Postitiv: Entgegen der Abbildung ist am Stirnrad schon ein Kugellager montiert.

Install was super simple and straight forward. Fit with no issues and there is no binding. Operation is quiet and now I don’t have to worry about weak plastic gears! As an added bonus, with these being metal, adds a little more weight down low! I’ll take what I can get!

Originally bought the rc4wd metal diff gears that are just a spur gear and square cut gear and it worked ok but it was super loud. These new gears knocked it out of the park the helical cut gears are precise and quiet, assembly was no different than when gears were changed last just used more grease this time. I like using dielectric because it repels moisture.

Great quality from injora. Fit perfectly in my axles and gives me around 20% overdrive which helps my little fcx18 lc80 pull itself up some gnarly climbs. This plus injora metal drive shafts and the fms metal transmission gear set is indestructible! Don’t forget to add some brass weights to the axles (inner and outer portal covers) and it becomes a beast of a little crawler.

This is a really good quality part! It doesn't weigh too much much but fits nice and snug. Make sure to add some hobby grade oil/lubricant to get the noise down and softness going. Didnt bind on me during the whole installation process and works very great! Highly recommend

If you own a newer model of the fcx18, there isn’t a need to replace these right away as the factory gears now come metal and will not fail as easily. The overdrive is definitely helpful and allows it to perform much smoother while crawling and more performance in its higher gears.Takes a little while for everything to settle in and break in, at least for me. May be a slight defect but front axle had slight vibration for aprox 15-20 minutes of run time

Had to grind axle ends to slide into diff. Injora usually has great products, this must be a dud. Once installed these 12/20 gears feel great.
