RC enthusiasts, listen up! These aluminum wheel hub hex adapters are exactly what your Arrma KRATON 8S BLX or KRATON EXB Roller needs for better performance and stability. Made from super strong 6061T6 aluminum, they're lightweight but tough as nails - way better than the stock parts. The coolest feature? They add +11mm to your wheel track width, which means your RC car will handle smoother and stay more stable during those high-speed runs and crazy jumps. The thickness has been upgraded to 19mm (original was only 8mm) for extra durability when you're bashing hard. The hex design grips onto your wheels super tight, so no more worrying about wheels coming loose mid-run. Comes as a 2-piece set with the necessary M3.5x24 screw pins included. Fits Arrma 1/5 scale KRATON models perfectly. The blue anodized finish looks awesome too - because who says performance parts can't look good? Whether you're racing competitively or just having fun in the backyard, these upgraded hubs will make a noticeable difference in how your RC car handles and performs. Easy to install and built to last through whatever punishment you dish out.
