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.

I see someone posted they are only about 19g** A: Jason C is wrong. They are 76g/pc. Mine were actually 74g/pc, but close enough **Q: Do you recommend doing all four wheels or just the front?** A: You want to lower truck and everything you can then add weight if need be. Rule of thumb is 60%Front/40%Rear weight biases **Q: Estas piezas son para la parte delantera o tracera del Trx4?** A: Son para las cuatro ruedas **Q: do I need hub extensions?** A: No they slide over your wheel hubs. Perfect fit. I love them. Has a nice added weight to the truck ## Customer Reviews ### ⭐⭐⭐⭐⭐ These seem like a decent value. *by E***Z on January 9, 2026* These brass weights seem solid for the money.
