A lot depends on the tires.

Yes, 4-low has A LOT more torque than 4-HI, also make sure your traction control is off if your slipping a lot in the snow or it will seem like you have no torque.

I hardly ever use 4hi myself, but you might be fighting the traction control. It will bog down hard when it kicks in. 4low turns it off.

Haha, 3 people beat me to it while typing.

I have a 2012 2dr 6m with 3.73's and mine has always done perfect in 4H. That being said, when wheel slippage is necessary turn ESC off. I almost drown mine in muddy water like that when I forgot to turn it back off after I restarted when stopping. Just like you say, it has no power. I only will use 4L after I have tried something and couldnt do it after a few tries or if loss of momentum will be an issue. These will tackle plenty in 4H without breaking a sweat.

I agree and I did upgrade to 4.56 gears. Looking to upgrade to 37" or 39" tires next set.

Is your driveway 70 degrees steep or something? I have a 2012 JKU with 3.21s, and while I wish for more low rpm torque for highway passing, in no way did I ever feel the need to have more torque in 4H in this last blizzard.

Uh, yeah, you should be in 4L all the time, unless it's just a fire road or something.

Had the same problems, driving on the "plowed" roads this weekend in 4hi then turned into some neighborhoods that havent been plowed out yet, hit the snowbanks and the first of the street and the truck lost all power and stalled. Used 4LO then and she worked her way all around the neighborhood

Talking altitude

I think being at 6800 feet at my has a lot to do with it. I installed unichip along with afe mods and it did wonders for low end power. now I never have to use 4 low at least not on my drive way. I still want to change gears 4 low is still a little high for me 1st won't hold back enough going down steep hills.

OK, on a 2013 Wrangler is it possible to permanently disable the ESC with the steering wheel trick?

I've got one on order and I'm reading conflicting posts about this.

Thanks
