Hey guys. So I'm looking to upgrade my clutch in my 2007.5 3500 6.7 Cummins. Has the Auto Trans. I just did my delete's and am using the Smarty JR. Everything is working great but I'm thinking I better upgrade my clutch ASAP before I start into any other modifications. I am not very fimilar with what clutch set up to run in these units. I want to build the engine up to roughly 600hp and I still do a bit of towing. For towing I mostly just pull a a 28'-30' enclosed trailer with sleds or quads to the mountains.

So ya, all in all what would be the best clutch to go with? Thanks

 

You will need a full rebuilt transmission since yours is an Auto.

Like a fully built ATS or something? Could I get away with just upgrading my flex plate and TC?
