Ready to upgrade your Arrma RC car? This HopsupRC kit gives you stronger, cooler-looking parts to replace the stock plastic ones. It's compatible with 1/8 scale Arrma Typhon 4x4 3S BLX and 1/10 scale Arrma Big Rock v3 models. You get 4 red aluminum wheel nuts, 4 matching aluminum wheel hexes, 4 pins, and a handy splined wheel wrench – everything you need for a solid wheel hub upgrade. The aluminum is CNC machined for a perfect fit, is much more durable than plastic, and looks awesome with its anodized red finish. It helps prevent those annoying stripped hexes and makes changing wheels a breeze. Lightweight but tough, these parts are built to handle crashes and high speeds better. A simple upgrade that adds both performance and style to your ride.
