That's been my point with the 4.24:1 T-case gears,
I think a 3:1 set or even a 2.5:1 set would give you
a nice reduction and not kill the top speed in low
range

That is where the samurai's are diffrent from trackicks,my 4 to 1's will do about 25 mph with 33's no problem, if you need to go faster than that I would just go high range. the samurai gears like the 8 to 1's also have a high range reduction like 24 percent so you could use high range more often with just the next size lower gear's like 4.30's,would love to get them for the snow!

I'm tempted to get something done, but it's like this.  

2 sets of 5.83 gears is $600,
4.24 tcase is $650.

R&p will definately give better high range driveability, and driveline life expectancy.  I ruined my front diff housing in a quagmire trying to apply full power to the front wheels only, the 583 gearde front would have lived because it was the pinion that pulled the housing apart. Maning, the torque inside the case is multiplied, not the torque going in.

Tcase is just infinitely better idea when wheeling, you can creep along at super low speeds, not have to feather the clutch on trails, no more bogging going up a steep hill.  But twice the torque breaks twice the parts.

That's precisely why I'm getting my cheapo diff upgrade (auto 4.62 to man 5.12) ...

If the diff's are geared high then the stresses from a low geared tcase will just break stuff. I just wanna lower the diff gearing as much as possible (yet still get 60-70mph top speed), then put tcase gears into it (including a 2 low kit).

I don't suffer from insanity, I enjoy it.

If your having troubles with low-low being too low then shift into 2nd!!!

My problem is I want a lower 1st and not a lower
3rd (Auto Trans) I have enough power with the
turbo to pull the taller gears, but there are times
when a lower 1st is a good thing, that and I like
the way the turbo spools quickly with the T-case
in low range, it makes 4 wheel power slides easy.

an automatic is another way to get lower gears, I will probably get one when I'm old  ;D

Do some math as to what is right for you and your purposes. For example in Hi Range in my Sami from stock to Lower gears and bigger tires:

4.16 T-case  +  4.62 Diffs  -   31" Tires = Tot Reduction

          12%            +          24%          -            16%           =       20%

In Lo Range I'm down around 90%. For you I'm not sure what gears your starting with but this example may help you in deciding what to get. Most aftermarket gears tell ya what the reduction is. For the tires you need to do some math. Someone out the might know the formula to calculate or know the #'s.

Hope this helps and doesn't confuse.
