I have a 12 v cummins with the nv4500 behind and I am looking to put a new clutch in it, I was thinking about the dual disk south bend and larger input shaft it's my work truck i haul a 40ft gooseneck and drive it every day just looking for thoughts on which clutch I should buy thanks for any info

 

my customers has had good luck with them.

 

I have the 3250 South bend dual disc with 1 3/8 shaft and the upgraded hydraulics, it feels stock. I like it alot
