The original ball bearings in my 416 seriously needed to be changed, as several of them had become quite loose and locking up from time to time due to tear. I thought that the original one's from Tamiya was way to expensive, so i searched for something cheaper, and i found it.
First i thought that the Yeah Racing was TOO cheap, thinking that they would wear out very quickly. But anyways, i tried them out.
They are very nice with the Yeah Racing logo etched on the bearings with a laser or something, and the blue rubber seals, wow!
They look very good on the car.
The first time i turned the wheels by hand after putting these bearings in it, i could feel that the whole driveline was alot more "free". Very little resistance.
About 6 months later the bearings still run perfectly, allmost cant tell whether they are brand new or used for a long time. I must say, theese are worth the money! Instead of the original, very expensive Tamiya ones, buy theese instead. Lasts longer and are cheaper. Can it be any better?
