Yeah Racing Tamiya TT-02 Rubber Shielded Ball Bearing Kit

I recently upgraded my TT-02 to brushless and I noticed that the drivetrain wasn’t smooth and the wheels vibrated a good amount. I never could figure out the problem. Meanwhile, my wheel hexes were heating up so much that the wheels literally welded themselves to the hex. I still could not figure out why (all my other RC’s came with real bearings, so I had no experience with bushings). Then one day my metal rear differential starting clicking. I took it apart and the gears were fine….then I noticed the bushing. The bushing had worn almost 2 millimeters off and the metal gears were over 200°F just from the friction. I then replaced all the bushings with real sealed bearings and the problems disappeared immediately. The drivetrain lost its play and the gears stopped clicking. Top speed is higher and the car just runs like butter. Definitely get rid of the stock bushings and get these for your TT-02! You won’t regret it.

Good bearings at a good price. I bought mine with my tt02 kit and was happy I did.
