Perfect fit Review: These seem like a decent value. - 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. ## Features - 【Compatible with】Designed for Traxxas TRX-4 Scale and Trail Crawler Car - 【Material】Quality Brass,Heavy Duty,Approx 74.4g/pc,add weight to vehicle,lowering center of gravity,increase stability when passing obstacles - 【Easy to install 】CNC machined for precision.Direct replacement for factory plastic steering knuckles Portal Gear Cover - 【Great Value】You will receive 4 Pieces ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B089YD13H8 | | Age Range Description | Kid | | Best Sellers Rank | #323,997 in Toys & Games ( See Top 100 in Toys & Games ) #1,795 in RC Vehicle Scale Accessories | | Brand Name | Hobbypark | | Customer Reviews | 4.6 out of 5 stars 217 Reviews | | Educational Objective | STEM | | Indoor Outdoor Usage | Outdoor | | Is Assembly Required | No | | Manufacturer | HobbyPark | | Manufacturer Maximum Age (MONTHS) | 144 | | Manufacturer Part Number | 19-2189 | | Material Type | Brass | | Model Number | 19-2189 | | Operation Mode | Manual | | Power Source | rechargeable battery | | Size | Small | | Supported Battery Types | rechargeable battery powered | | Unit Count | 4.0 Count | ## Images ![Hobbypark 4pcs Heavy Duty Brass Steering Knuckle Weight Outer Portal Drive Housing Cover Counterweight Block for Traxxas TRX-4 1/10 RC Crawler Car - Image 1](https://m.media-amazon.com/images/I/61-a2yXl-lL.jpg) ## Questions & Answers **Q: Are these 76g a piece?

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 ### ⭐⭐⭐⭐⭐ TRX 4 high trail *by D***N on May 7, 2026* Nice added weight down low for TRX 4 high trail. Mor stability!
