Has anyone heard how the new SB Double Disk Clutches hold up, and what their street manners are?

 

Mark, I ran the 3600 lb. 12-CB SBC for well over 30K miles on my 03 I sold a few months ago. They have some really good street manners, and this was with 3.73 gears and 37's. They are noisy when the pedal is depressed, just so you know.
Never any indications of any slippage at all. Very good clutch for hard launches, or even backing a heavy trailer. I liked it better than the ConFE single I had before it. BTW, my setup was somewhere around 550HP with this clutch, and it was rated for 650HP.

 

Thanks a bunch Fred!
I don't know if I am allowed to ask this, but can you tell me roughly what it cost you so I can budget?

 

Is this a 12" or 13" clutch? (rounding the decimals)

 

13 inch. Check your PM.
