RC enthusiasts, if you're running a Team Associated RC10 B6.4D, this FastEddy bearing kit is exactly what you need to keep your ride smooth and fast. This complete set includes everything you need: (8) 4x7x2.5mm bearings, (2) 5x8x2.5mm, (8) 5x10x4mm, (2) 5x12x4mm, and (4) 10x15x4mm bearings - all sealed to keep out dirt, dust, and debris that can wreck your performance. Now, quick important note - bearing sizes can sometimes vary depending on when your model was manufactured and what hop-ups you've installed, so definitely double-check your specific rig before ordering. But FastEddy does their best to keep these kits updated based on the most common configurations. The quality on these bearings is legit - smooth rotation, minimal play, and they hold up well to the demands of competitive bashing or racing. Swapping out worn bearings is one of the easiest ways to restore that like-new feel to your RC car, eliminating drag and vibration that robs you of speed and control. Whether you're doing a full rebuild or just replacing bearings that have seen better days, this kit saves you the hassle of buying individual sizes separately. The sealed design means longer life between maintenance sessions too. Serious racers know that quality bearings can shave seconds off lap times, and casual bashers appreciate the reliability. Don't let worn bearings slow you down - this complete kit has you covered for whatever your B6.4D needs!
