Advice sought on T-Case crawl ratio choices
After a recent stall 'n' lurch extravaganza up the Doran Loop obstacles
in Calico, CA , and a couple of key words uttered by fellow Jeeper ("Are
you set up with the 4 to 1?"), I have done some research and
confirmed that just sizing up the gears in the diffs is not enough to
really crawl in control, when equipped with a stock NP 231 T-
case in my 94 YJ. (Yes, I checked out all the online gear ratio
calculators.)
So my options as researched so far are:
Get a TeraLow 4.0:1 kit. Pros: Doesn't mess with 2wd or 4WD Hi
or street driving. A reasonable $1200 outlay. Bolt-in install in the
exact same space as the NP231 case, so no driveshaft mods needed.
Compatible with TeraLow's 2WD Low option (which might help crawling
and turning at the same time).
Cons: Uses the drive chain, not helical cut gears like an Atlas or
Dana 300 Tcase. (But can opt for a JB conversions wide chain
replacement). I also have been into my t-case twice already and
don't find it a real enjoyable process.
Dana 300 T-Case. Pros: Small size, all gear internal, great crawl
ratio. Cast iron heavy duty housing. Mid-Range price on parts.
Cons: More labor inten$ive to clock, adjust, fit. Would require
driveshaft lenghtening or shortening.
Atlas II. Pros: All geared, great reputation. New and shiny.
Cons: Pricey at $2,500 for parts, and still another laborious install
and fitment.
What to do? Any other options or opinions?

Re: Advice sought on T-Case crawl ratio choices
With what you have already in your rig what's another $2,500? You didn't
skimp on the axles... don't skimp here.

The money flows out when I've got a nice inflow. Right now, the pipes
are a little constricted.
