First off, holy smokes Batman. Was surprised how heavy these were even though I knew from the description before purchasing lol. Used these on my new K5, it definitely kept the wheels planted. They fit decent, I say that because one out of 4 wouldn't take the bearings properly. I ended up making it work but surprised about that coming from Injora. Used alot of their products on my SCX24s previously np. I find these to be the only brass you would ever need. I currently only have aluminum deep dish wheels and brass spacers. With these covers, they added weight tremendously. Now I feel like everything else can just be aluminum as far as metal upgrades go. These do fit all four, front and rear. This is all the weight you'll need, unless you're trying to build a tank. Do you. One things for sure after adding these, my stock motor was getting pretty warm. Be sure to add grease. Overall, I was pretty happy with these. Especially for the price compared to other brands. These were decent quality. Definitely the right amount of weight as it says in the description. Good luck!

On the Injora website it recommends +2 mm extended brass hexes, these came with my purchase to my surprise. Went on easily enough, used the +2 mm brass hexes, helped the performance of both an FCX18 K10 and FCX24 K5. I only placed them in the front to keep the overall weight down.

Really good quality, fits like it’s an OEM part. You can feel the weight it adds and the benefits of the lower center of gravity. Injora ftw.My FMS FCX18 will have all injora upgrades.

I really like the way my little fcx24 power wagon climbs with this much weight down low. They fit perfectly (they replace the outside portal axle cover) m gave me a chance to check out the grease in the portals.

The fit, finish, installation and functionality are all good. But I don't suggest running all four of these. Maybe a pair on the front, and lighter ones on the rear. With all four it's front and rear weight balance isn't forward biased enough. It rolls over less, but the climbing suffers.

Fittment and machining was great.

These add A LOT of weight to my fcx24 k5 blazer BUT when I tighten them down to seal them the gears are stuck. It moves really slow on 1st gear and gas a ton of torque twist. It won't even move in second gear. I have to back the screws up to where the gears are exposed - not good if when dirt and rocks get in there, especially since I added a little grease to the gears. Instead of the extra roll pins and hexes it would've been better to include inductions. I totally missed that the pin inside the cover is about a flea's hair thinner than the pin used to set the wheel hex. It took me hours trying to force the pin into the shaft until I tried the old one. I fit know if these are defective and weren't machined to the right diameter or depth but they're going back

Habe nichts auszusetzten, Wirkt sehr hochwertig, ist aus soliden Stücken gefräßt. Desweiteren sind breitere Radmitnehmer, ebenfalls aus Messing, dabei welche die Spur etwas verbreitern und auch nochmal gewicht bringen. Das Fahrverhalten ist deutlich besser an hängen, steht deutlich besser am Berg.Einziges Manko, wofür Injora aber nichts kann:Der Originale FMS Lenkservo kommt etwas an seine grenzen. Auch das Zweigang Getriebe ist damit mehr oder weniger hinfällig, im zweiten Gang merkt man der motor hat mit dem zusatzgewicht zu kämpfen.Für mich nicht schlimm, schnell fahren war eh nie das Ziel und ein stärkerer servo ist schnell verbaut.Man sollte das Gewicht der Messingabdeckungen nicht unterschätzen, merkt man dem Modell deutlich an. Im Gelände positiv.Auf der Straße kann man es kaum noch nutzen mit den gesperrten achsen, da die räder nun sehr stark Radieren, was aber klar ist und für mich kein Problem.Kann es nur empfehlen, verbressert die Fahreigenschaften stark und dinge wie blei in den reifen kann man sich sparen.Sollte man auch die stangen und sämtliches zeug gegen messing austauschen wollen braucht man definitiv nen stärkeren Motor, wobei meiner meinung nach die Portalabdeckungen reichen, mit mehr Messing wird es eher zu schwer.
