Question Which Torque Converter?

Well fellas it seems I have a bit of a dillema on my hands. I can't decide which torque converter to get. This is gonna be used on my 2006 K1500 crew cab 6.0 with a radix. I plan on running a FLT level 5 4L70E behind this as well. After I get the trans in I am gonna pulley down some and get a street and dyno tune from Nelson Performance in San Antonio. I do tow from time to time with this truck. Anywhere from 2-4k and 5-8k on rare occasion. So it needs a converter than can still handle the stress of towing and not be too loose and have problems towing. I am also gonna get a big tranny cooler to keep the temps down. The truck currently has 265/70/17 bfg all terrains and 4.10 gears. I have been doing alot of research on the subject reading up on old threads on here.

So far its between the Vigilanti 10.5" lock-up Multi- Disc 3 plate 2400-6000 RPM's http://www.converter.com/vigilante.htm If i was to get this converter it would more than likey be a 2400 or 2600 stall. Edit: I e-mailed Precision Industries earlier and asked them what they thought, waiting on a reply from them.

Also, I emailed yank and told them what I have planned for the truck and that I do tow. They recomended the Yank SC3000 for me. A few people are running the Yank SC2800, would that be ok for towing? Does yank make a SC2600 or SC2400? I just think a 3000 stall would be a little high to use with a roots type blower. Here is the link to the yank converters: http://www.converter.cc/converters/truck/truck_main.htm

From reading up on old threads here it seems the SC yank series converters are a little looser than the Vigilanti ones. It also seems you want a bigger converter if your gonna tow so a 9.5" would be outta the question. There are also a few people that say to stick with the stock converter. Would this be a wise idea, or would I just end up blowing up my new trans? Thanks for all the input/help guys

If you are going to tow anything with some weight I say stick with the stocker. The stock converter is very good, weakness being the the clutch. It won't take repeated WOT locking of the clutch I've heard.

I have nothing but praise for the PI converter and their service.

I sounds like you might want to look at the Yank TT2600 it should be tight enough that you will barley even notice the difference from stock. It also retains the full towing capacity of a stock tc.

So the stocker isnt that bad. Hmmm. I read one thread on here where you swapped the stocker back in when you took the PI out because you thought it was messed up. How did you like the stocker when you had it back in there? https://www.performancetrucks.net/fo...rque+converter

I thought about that, but I don't think it would be good behind a supercharged application. I think they might balloon out.

The one for $750 eh? What is it currently stalled at now? If i was to have it stalled to 2400-2600, what would it stall behind a supercharged application like mine will soon be.
