Thanks!

 

I was actually going to post a thread but since this is what I was gonna ask I'll just ask here. On the fastman website it says for the 5.9 use a 50mm if towing is a main concern. I really am looking for more low end so what do y'all think on this?

 

Go with the 50mm. Towing requires low end.

 

What about low RPM crawling when in 4wd? Will 50 mm be good for that too?

 

yep. low end grunt is what you want for that.

 

That's exactly what i wanted to hear, Thanks again!
