does anyone run a twin plate clutch
 

as above does anyone run a twin plate clutch on a bc type box ??
please and thankyou in advance

or know of a single plate that will cope with over 400bft ?

Do you mean 400 FtLbs of torque?

Yes please excuse my gramma ole bean

Can the bc box handle that much torque?

I asked if anyone had a twin plate clutch fitted to a bc type box not the torque capability but thanks for your constructive input

I wasn't sure if "bft" was another measure of torque.

As for your original question, I think the answer is going to be no.

Most people venturing past 200-250 FtLbs of torque look at other gear boxes.
