Hobbypark 4pcs Heavy Duty Brass Steering Knuckle Weight Outer Portal Drive Housing Cover Counterweight Block for Traxxas TRX-4 1/10 RC Crawler Car

These brass weights seem solid for the money. Mine came in old looking packaging that was yellowed and gross looking, but I’m not sure if that’s from age, or the material itself. I had some brass dust on the parts themselves, but that wiped off and the actual machining looks ok. For $25, I’d say they are a solid performance upgrade. They are very heavy, and are pretty much as low as you could get. They even fit behind my SSD wheels, I’ll be it, it’s tight. I would recommend these at $25.

They're exactly what I wanted and they fit perfectly fine and they're actually was two leftover screws which was cool I'll buy from them again and now I'm set because the original truck weight is 5.79 lb and now I'm above six almost seven I think.

I'm usually a Treal snob and often use the 95g weights but cause clearance issues even with their own wheels. I found these work fine if you just switch to M2.5 button head screws on the treals the two sets worked with stock offset wheels and hexes(TRX4's hate negative offset with a goofy scrub angle changes and clearance issues). Leaving the stock portal covers on makes these among the easiest to use. Good bridge between the 40-50g and 94G+ covers. Isn't exactly pretty, but works.

They are dense and heavy, extremely clean machining. The price to quality ratio is very good. Fit right on, I got the correct screws, and made a noticeable performance difference. Don’t really see how people can leave a one star review crying, even if they did get the wrong screw. For the price, I wasn’t even expecting to get hardware. It was just a nice bonus

You will need hex extenders to fit the stock wheels. I will try some 8mm. I am concerned about fender rubbing but have tried three brands now and same story with each. Otherwise nice value compared to other brands and MUCH closer to fitting over the hot racing brass and better value.

Gotta give these a 5. I got some new tires that were a little bigger than I thought which led me to get 100 mm shocks since the stock 90s weren’t doing it, and that made it sit fairly high so I then needed some weight on the axles. I settled for these as they were the best option compared to all metal axles and stuff, they really add some good weight to it. I wish I got them before I changed the tires and shocks because they would make a big difference then too. They definitely help now that it’s taller but it still has a little trouble on really steep stuff. Comes with screws, but it was a little tricky to get them on, although I got them with some persistence. Overall they solved the problem I had, so I would recommend them again if you need to add a little weight to the axles!
