got 5.13s going back to 4.10s

No as to not hijacking this thread, what about a supercharger vs a gear change?
It's not the computer, it's eyes that aren't even close to being from this decade. I make it small enough to see the pictures, I'm not going to be reading the text. You keep it that small and your eyes'll be like mine much sooner than you think. Now on to posting picts, if you bother to read about doing that on this site you'll see the numbers 800x600. As you're the computer expert I'm sure you'll eventually be able to figure that one out.

cant please everyone, i guess...
Hi all. I'm still new to the jeep world, got my Unlimited X a few weeks back. I'm still struggling to figure out this gear ratio topic. I can't wrap my head around how regearing will help with highway cruising. For example, with 35's and 4.88 in 6th gear would give almost exactly the same RPM's as 4.10's down shifted to 5th.
Why bother with regearing? Unless 6th is totally useless even on flat highway, which I don't think it would be, why not just downshift? I can understand for an automatic, but why a 6 speed? Is is better to produce the gearing in the rear end rather than the transmission? It seems like the shorter gears would only be beneficial off road when you want a lower 1st gear. Being new to my jeep, I think 1st gear is a plenty low enough as it is. It's almost not worth using on the street, just start in 2nd.
It seems to me the problems people are having on the highways in the mountains are more a lack of horsepower. Regearing isn't going to fix that...

Agreed, this is definitely more a question of power than gear. Thin air in the mountains and trying to get some more power would be best served with a CAI kit, the most bang for the buck. A programmer and premium setting would add nominal power but the best available for our Jeeps is the Hypertech, which is a poor programmer and I wish Superchips would recognize just how under served this market is. Premium vs Regular has a nominal percentage cost increase, but it won't do you a lick of good without a programmer.
Shedding 100lbs of weight is also about the same as adding the 10hp you're looking for. Using that back seat? Aluminum vs Steel wheels can save as much as 25lbs and because that's rolling resistance, saving 5lbs a corner makes a bigger difference than removing static weight.
Anyway, it doesn't take long to add lots of weight to an already underpowered platform. Larger tires, new bumpers and a host of other items really squashes the power to weight ratio. Getting any power back in is painfully expensive and the avenues to travel are really narrow.
