Default Ceramic Diff Balls???

Ok so ceramic diff balls are made from silicone nitride but I've seen different hardness ratings for silicone nitride. So what is the best hardness for diff balls and where is the best place to obtain them?

Chris

silicone nitrite or ceramic nitirite is a very hard material.so its highly unlikely.

i have got xenon diff balls. and i bought them for a pretty penny.. hehe so if they won't scratch, then i will just buy a sh*t load of diff plates to replace hehe. thanks alot!

i am a parking lot basher... so that's good to know... i am still looking for a good way to fully protect my diffs ... sigh.. evo 5....

i know.. the car was not meant for parking lot bashing, but i thought the diff covers were gonna do the trick... hehe

I just run high grade steel balls. They are cheap so throw them away when I rebuild my diff.

The steel balls have a higher coefficient of friction against the steel rings than the ceramic balls do. This make the diff not slip and stay smooth longer. It also lets me run the diff looser without slipping so I get better on power steering.

For 1/12, silicon nitride diff balls are the best money I have ever spent. I have used the same set of Avid balls for a year and a half, probably 125 race sessions, and are still good.

Ceramic will out last steel balls by a large margin. Also steel gets hot and holds the heat in. Ceramics do not have that issue.

Ceramics will last a long time if there kept clean no matter what kind.

Why not put the evo6 / tb04 gear diff in your car?
