I've got an 04 dually 4x4 ext cab 6 speed. The factory clutch is finally on its way out. I have done headstuds and egr delete. I currently have a banks six gun tuner on it which needs to be changed, but that's a different question for a different day. I don't plan on any wild tunes ever. Possible some where in the neighborhood of 400 to 450 hp. My biggest concern with the purchase of a clutch, is the fact that the truck is geared 3.73 and I occasionally tow over 20000 lbs. But also it is my daily driver. Any advice is greatly appreciated!

 

I went with a model from southbend
and have had no complaints or regrets.
I'm running 450+rwhp with 3:73's
They should have something for your truck too.

 

Valair Single Mass Flywheel

Single or double disk? Noise and stiff pedal are not factors. It's a truck people, not a lincoln or caddy. I just want the toughest clutch I can get that will hold up to daily driving and extreme towing loads. I haul hay, an 11 ton cat track loader, an 8 ton cat dozer, and a John Deere 2849 with front end loader and 3 point attachments. I know I am way over loading a 350, but its all I have right now.

 

Dual Disc

So I should go with the valair solid mass flywheel dual organic disk kit? Will I need to upgrade the hydraulic system in any way?
