Product is very high quality and although mine came warped on one set all I needed to do was explain the situation and shortly after Vicky from Injora reached out and sent a brand new set free of charge and without hassle. Thank you Injora. They stand by their product!

Queste coppie coniche hanno un profilo troppo affilato. Faticano a girare una sull'altra, nonostante l'abbondante strato di grasso applicato.Il risultato è che il movimento della macchinina risulta poso modulabile, scattoso e il motore si surriscalda notevolmente.Inoltre sono leggermente grosse: quando si chiude il coperchio in plastica del differenziale, non bisogna stringerlo troppo altrimenti preme sugli ingranaggi e li frena ulteriormente.Farò il reso come prodotto difettoso appena recupererò delle coppie coniche originali

One set was tight. I even tried to shim them.The other set in the same diff fit perfectly.I may have got a defective set.Update- I've since changed my review as Injora reached out to me for product replacement.I've never have have a company do that.

Went for a speed build with overdrive in diffs and transmission and was not dissatisfied. Topping out at about 8mph with the 180 pro motor.

They bind up under load when trying to climb and the tourqe steer is horrible.

Used these to overdrive the front and worked great. Like most or all of the Injora products

Super durable. After putting 40:1 transmission gears in I quickly stripped the stock plastic gears. Replaced with these and have not had any problems. Matter of fact immediately after replacing the factory gears I broke the factory driveline. So replaced with steel drivelines and it's all good now.These are designed with a key notch in the ring gear. This way they do not depend on being pressed on the housing to spin the carrier. Much better design than the meus brand gears

Even without shims they bind. Probably the worst set of gears I've ever gotten. Have the stock style in all my trucks and decided to up over drive in one of them and this is a no go. Probably see if I can return them even tho I have installed them. Would not buy over drive gears again

I went from the plastic straight, cut gears to the metal straight cut gears with no difference in sound very quiet. I switched over to these today, the heli cut and overdrive front and rear as I’m going for a speed set up, they definitely have a little bit more noise in the axles, but these things are made with precision!! And it’s really nice that they include the shims. I did not need them as I have a bearing upgrade to the whole car.
