This is an optional Avid RC 2.5x6x3mm "Steel" Associated/TLR Differential Thrust Bearing. This thrust bearing makes working on your diff much easier. You no longer have to worry about losing a diff ball or getting covered in grease when you rebuild your diff! The steel thrust bearing delivers an economical, easy to adjust diff. However, they will require more frequent replacement and are not as smooth as carbide or ceramic.

Avid RC 2.5x6x3mm Associated/TLR Differential Thrust Bearing (Steel)
I see that these are very popular, but I have used the TC and ceramic versions and must say that these are sub-standard parts. I have one TC version that fragmented into several pieces. I bought mine directly from AVID and want to share my experiences: First of all, this assembly is much thinner than a traditional thrust washer set-up--much thinner. So, it is vital that your thrust spring and t-nut are new--otherwise it will loosen after about two laps. The MIP super diff thrust spring and t-nut are the way to go. Second, even if the thrust spring and t-nut are new, the diff screw will thread all the way through the t-nut to the other side banging on the opposite side's CVD. To eliminate this, I have the only one I am currently running sandwiched between two older thrust washers. It works, and is a fix that AVID recommends when you talk to them. Joon, at AVID, got very offended when I tried to explain the issue and told me that no one he knows of is having problems like this even though he knew exactly what kind of problems I was having sight-unseen and gave me a recommendation to fix said problem. So, AVID knows and is not really trying to correct the issue. Making the balls bigger would completely fix the problem as AVID's thrust assembly would be the same thickness as a traditional thrust assembly. Several people at our track have tried this product and have had the same result. I'm going to stick with the B-Fast thrust assembly and would advise the same to all of you considering this product. It may be the "it" product to have, but doesn't cut it endurance wise. Not worth $10. AVID makes a lot of exceptional parts, but this one is a stinker......
