This FastEddy bearing kit has exactly what you need to keep your Team Associated RC10 T6.1 running smoothly! The set includes all the essential sealed bearings: (4) 10x15x4mm, (2) 6x13x5mm, (8) 5x10x4mm, and (8) 3x7x3mm sizes. The sealed design is crucial for RC cars because it keeps dirt, dust, and moisture out while retaining lubrication inside. This means smoother operation, less maintenance, and longer bearing life compared to unsealed options. The precision manufacturing ensures consistent performance and perfect fit for your specific model. FastEddy is known in the RC community for quality bearings that offer great performance at reasonable prices. Before ordering, it's always smart to double-check your specific model and any upgrades you've installed, as bearing requirements can vary slightly between production dates and modifications. Installation is straightforward if you're familiar with RC maintenance - just replace your old worn bearings with these new ones for noticeably improved performance. The difference in how your car rolls and accelerates is immediately noticeable with fresh, quality bearings. Perfect for racers who need reliable performance or hobbyists who want to restore their RC10 to like-new condition. Much better than trying to source individual bearings separately - this kit saves time and ensures you have all the right sizes. Your RC car will thank you with smoother operation and better overall performance!
