So if you're into Arrma RC cars and want to upgrade from those stock plastic hex nuts, this aluminum set is seriously worth checking out. These are 17mm wheel hex nuts specifically designed for Arrma's 6S BLX models - we're talking Typhon 6S, Mojave, Felony, Infraction, and the Limitless roller. They directly replace part numbers ARAC9416, ARAC9763, and ARA311035, so you know they're made to exact specifications. The blue anodized finish looks awesome and the material is 6061-T6 aluminum alloy that's both lightweight and super strong. They're CNC machined for perfect fit and the PTFE coating makes them really durable against wear and tear. What's cool is that reducing rotational mass with these aluminum parts actually improves your car's performance - better power transfer, smoother handling, and just overall more responsive driving. The kit comes with everything you need - 4 aluminum wheel hexes, 4 matching wheel nuts, and 4 pins to secure everything. Installation is straightforward if you're familiar with RC maintenance. The blue color gives your ride some custom flair while actually being a functional upgrade. Much better than stripping out those plastic hexes when you're running high power. If you're pushing your Arrma hard on 6S power, these aluminum hex nuts can handle the abuse way better than stock.
