I need a ceramic throw out bearing and shosource doesn't have any in stock. My question is has anyone bought from shonut performance recently? Are they still in business and selling products? I've never purchased from them and can't confirm they still are in business. Can anyone confirm that they are still,and legit? Thank you.i really need that ceramic throw out bearing and can't afford to lose money,and or time.

Did you send him an email or message? He is SHO NUT on the forum and there is a contact button for shonutperformance on his website. I think [email protected]

I imagine his SHO business is slow seeing the low number of cars left. Hopefully he can help

SHOnut (Josh) is still in business. If you email him he is pretty good at responding. I know that the Ceramic TOBs have been unavailable for a while. Several people waiting on them. From what I understand, Josh builds them from stock TOBs and there might be a shortage of one particular part that he needs. Send him an email and see what he says.

A new TOB will be fine for your setup. If ceramic is not available I wouldn't wait for one to put it back together. Did you buy a clutch kit? Those usually come with a TOB in them

Like I said you have to email Josh and see what he has and what is doable at any particular time. It's a small side thing so not a bunch of inventory sitting around. He is/was great at sourcing and getting stuff done for this platform. Such a numbers drop off so email/message

I was gonna pick up the O'Reily clutch kit tomorrow. I haven't driven the car in a month,since it broke.i just parked it and haven't touched it. Will the tob in the kit last? How long? Or would a shosource revision b tob be better than the O'Reily tob in the kit? I did email Josh at the sales email,so we'll see what happens.thanks Chad.

Everything should fit and work fine if it's a good replacement. I assume the o'reilly kit is rebranded sachs/valeo/oem design replacement. Never had to use a ceramic TOB on my cars. I don't track or beat them from a stop (anymore). I'll push it but I'm not trying to throw a differential pin either.

The Rev B TOB is the improved version, but I thought some clutch kits got the Rev B version. Check with Shosource to see if they know if the o'Reily clutch you are looking at has the Rev B TOB or not

It is a rebranded Sachs clutch kit. I like to get on it couple times a week,but also if someone lines up with me at a light,I will run them.so that's why I'm concerned about getting ceramic tob and being done with that issue.

FWIW, the ceramic TOB was not necessarily developed to make a longer life bearing, rather, it was developed to lessen the effects of skidding wear between the bearing contact face and the clutch fingers. Many early SHO clutch failures were caused by the bearing face wearing away or even cutting through the clutch release fingers, and this occurred with both the Rev A and B TOBs, though the Rev A bearings, which had a smaller throat inner diameter, weren't in service all that long anyway.

The fellow who proposed and developed the "ceramic" TOB was an aerospace and materials engineer, and he proposed that the high spinning mass of the bearing was causing skidding wear between the bearing contact face and the clutch fingers, and that reducing the mass of the TOB's guts would lower its inertia and allow it to track the spinning clutch fingers without skidding.

He proposed swapping out the steel balls in the factory Rev B bearing with ceramic balls, which are lower mass and smoother than steel balls, and so in theory should produce a bearing with lower inertia.

I was one of the initial testers of this ceramic bearing, because I was, at the time, solidly open tracking a Gen 1 '89 SHO, and due to that use, I was changing clutches more often than some of you change your undershorts, so I could monitor clutch finger wear pretty readily. My impression at the time was that the ceramic TOB lowered the wear rate of the clutch fingers compared to the factory OEM Rev B bearing.

So there...

Omg.thank you for that information sir.that is definitely more in depth information on those bearings. Well done.
