Hey RC crawler enthusiasts, looking to upgrade or replace your wheel hubs? This set from INTEGY has you covered. You get four brand-new, high-quality brass wheel hubs. The specs are crucial: they have a 12mm hex fitting (so they'll mate with wheels that have a 12mm hex bore) and they're 8mm thick. Brass is a great material for hubs – it's durable, has a nice weight to it (which can help with lower center of gravity for crawling), and looks awesome. These are genuine INTEGY parts, known for good craftsmanship in the RC world. They're listed as compatible with popular Axial models like the SCX-10 and Wraith, as well as the Tamiya CC01 chassis. Always good to double-check your specific model, but for many crawlers and trail trucks, these are a direct fit. Installation is a standard DIY job. Whether you're building a new rig or fixing up an old one, these solid brass hubs are a reliable choice.
