I was wondering about to install a torque converter with more low stall speed in my Jeep.
Which is your opinions about that?
Where Can I buy it?

The main reason is being able to improve gas mileage.

Most performance builds look for a higher stall converter. I'm not sure what benefit you would get out of a lower one.

If you have a lockup converter changing the stall speed will make no difference.

What are your vehicle specs?

Specs:
4.6 Titan stroker
C/R about 8.8/1
Bulltear custom forged pistons (dish about 32 cc)
Supercharger MP90, max 5,5 psi (...for now)
Ring & pinion, 4.56/1, 33" MT BF Goodrich, Rubicon +4,5"

I think that a low stall speed converter, I can run all time with the engine at lower rpm .

your stall speed has nothing to do with lockup.stall speed will only affect your launch or take off.if the motor makes enough low end torque a lower stall speed might work great and give improved mileage.im looking at doing the same on mine.lockup is there to help with mileage and decrease slippage in the convertor and will only work in 3rd and 4th.it has no effect at all in 1st and 2nd as the computer will not allow the convertor to lock up.

I think if the slippage is lower, I can improve the mileage, although the speed launch will lower.

I can think of alot more things to do to my Jeep before I got on the lower stall speed converter rabbit trail.
Ever replace your headpipe with one without the "crush"?
