RC enthusiasts, listen up! If you're running a WL K989 (or the K969, P929 models) and want to upgrade your ride's look and performance, these Y-shaped wheel hubs are exactly what you need. This set comes with four identical black hubs that give your RC car that aggressive, sporty appearance that stands out on the track. The Y-shaped design isn't just for looks - it provides good durability and weight distribution for better handling. Installation is straightforward if you're familiar with basic RC maintenance - no special tools required, just some basic knowledge of how to remove and replace wheels on your specific model. The black finish holds up well to rough use and gives your vehicle a sleek, unified look. These are perfect replacement parts if your original hubs have worn out or if you just want to customize your RC car's appearance. The quality is solid for the price point - they're durable enough for casual bashing but look good enough for display too. Great for both beginners looking to learn more about RC maintenance and experienced hobbyists who want affordable upgrade options. Since they're sold as a complete set of four, you can do a full wheel replacement at once rather than buying individual pieces. Just make sure your current tires are compatible or plan to get new ones that fit these hubs. Awesome budget-friendly way to refresh your RC car's look without breaking the bank!
