Does the Street Twin require a special throwout bearing?

My LT1/T56 with a couple thousand on the new street twin is squealing during shifts, so I think I need a new T.O. bearing already. McLeod wants around $250 for a replacement! Is theirs special somehow? Will a stock GM T.O. bearing work instead?

If stock works, is a dealer part the best bet, or what?

Thanks, guys.

here is a McLeod



here is stock, well centerforce



do you already have a mcleod in? twin clutches usually require more pressure so that explains the beefed up T.O. Bearing.

Thanks, but you showed the Mcleod HYDRAULIC throwout bearing used for push-style clutch conversions, such as in their old-style LT1 kit, IIRC.

I have their traditional style one that came with my new-style Street twin. That setup retains the factory hydraulic slave cylinder and uses the stock fork to move the TO bearing with normal, pull-type action. My McLeod bearing looks like a stock TO bearing. But, I don't know it the length is the same, or if it is upgraded somehow, and don't really want to pull the clutch before I have parts.

My searching found conflicting statements - some had been told the McLeod uses stock TO and pressure plate, but the McLoed site mentions 'angular contact for better durability'. I'm hoping for a good alternative from someplace else. After waiting several mos to get my clutch kit and then finding it had no holes in the flywheel, and waiting 1 year+ for the master cylinder, I'd rather not deal with McLeod for any orders if not absolutely necessary.
