Hey RC enthusiasts, if you're running a Traxxas 1/16 scale model like the Mini E-Revo, Mini Slash, or Mini Summit, these GPM aluminum knuckle arms are a solid upgrade from the stock plastic parts. This set includes both front and rear knuckle arms in this really nice blue anodized finish that looks awesome and adds some custom style to your ride. The aluminum construction is so much more durable than the original plastic parts - we're talking better impact resistance, less flex during hard driving, and overall improved performance when you're bashing around or racing. The fit is perfect since they're specifically designed for these Traxxas 1/16 models, so installation is straightforward if you're comfortable working on your RC car. Part number ERV021-B if you need to cross-reference. Once installed, you'll notice better handling and stability, especially in corners and when landing jumps, because the aluminum doesn't flex like plastic does. The anodizing isn't just for looks either - it helps protect against corrosion and wear over time. Whether you're replacing broken stock parts or just upgrading for better performance, these knuckle arms are definitely worth considering. They're one of those upgrades that actually make a noticeable difference in how your RC car handles and holds up to abuse. Plus, that blue color just makes your Mini E-Revo, Slash, or Summit look way more custom and serious. Definitely a recommended upgrade if you're tired of breaking plastic knuckles or just want to improve your rig's durability and performance.
