SHOULD YOU UPGRADE THAT PART TO ALUMINUM?
If you break the same part more than once, it’s only natural to wonder if there isn’t a stronger version available. Many brands offer aluminum versions of certain plastic parts, and if they don’t, chances are the aftermarket does. The most common candidates for aluminum upgrades are arm mounts, C-hubs, rear hub carriers, and steering knuckles. If you’re breaking these, consider making the aluminum upgrade.
You may also find aluminum arms for your model, but use caution with these; unlike plastic arms that flex and return to shape, aluminum bends and stays bent. That’s not a problem for items such as arm mounts and hub carriers, which don’t really see bending forces. But for suspension arms, aluminum is not the best choice. If you want them for style and you don’t crash into stuff, great. But if you’re out there breaking plastic arms, you’ll bend aluminum arms. Or that strong aluminum arm will transfer crash loads to other parts, and they’ll break.
If you you’re having trouble with arms breaking, see if RPM offers arms for your model. RPM uses an extra-tough plastic, and the parts are generally thicker and more flexible than stock, so they don’t break—and they don’t cause other parts to break, either.
Ready for action. RPM offers arms for tons of different models, and many come in colors. Here’s a complete set of RPM arms for the Traxxas T-maxx and E-maxx.
