Give ya a buck.

Come on, Paul! The NP-231 is a solid t-case. The gear ratio isn't the greatest, but if you're riding on anything less than 40's, your good.
Take your dollar and buy me a cup of coffee! ;D

I agree with Justin, the NP231 is a pretty good transfer case, and can be upgraded relativiely cheap. Thicker chain from a S-10 version, 2wdLO kit and even a 4:1 and you will have less $$$ into it then an Atlas or a built D300.
My question is: Where do you get a cup of coffee for only a buck???? ;)

I've sheared the front ouput shaft off one, sent a chain through the case of a second, and stripped the planetaries for 4 low in a 3rd. They're not that strong. I wonder how my zuki case is going to hold up??

What kind of drive train were you running to do all that damage. I've seen guys run them behind a 350 SB and NV4500 with no problems. Since they are chain driven, the chain can strech over time and possible need to be replaced, but I have never heard of one breaking off. I know the transfercases in the 87 wranglers (I don't remeber the name of them) were crap, but the NP231 is a much better case. Jeep has been using them for over 21 years now.

i built a HD 231. dodge uses a 231 in the 1500 ram. i used the internals just like JBCONVERSIONS to make a hd 231. the front output sheared right off yolk and all flush with the t/case housing. so that's 1.
i snapped a chain in a 93 231 just by pulling a 3/4 ton ford out of the mud. that's 2
the gears in the last was for 4low and was stock and just wheeling with sawzall fenders and 31's.
i can elaborate on any one, just ask.... 231's just aren't that strong.

Here is a thread I saved a while back about the NP231.
http://www.pgh-offroad.com/forum/showthread.php?p=89437
There is some great stuff about using the Chevy and Dodge versions to beef up the Jeep version. There are a few actual facts in the write up like the NP231 can handle 1940 ft/lbs of tourque!!!! and the NP242 is in the 1400ft/lb range. Out of 25+ posts, the only chain breakage was a worn out chain. There are a few guys that managed to explode them, but under pretty stressfull situations, but the D300 are known for exploding under high stress situations.
For the $$$ I don't think the NP231 can be beat( my opinion). If I had the $$$ I would put an atlas in, but then the t-case would be worth almost as much as the rest of my Jeep ;). For the trails we run, I don't see any NP231 t-cases breaking unless something else like a busted spring/ control arm/ rock etc... causes it to break.
By the way the avitar for post 25 and 26 are worth checking out even if you don't care about the NP231 ;)

supposidly when i bought the zuki it had a 6.5:1 low range kit in the stock case. it says 33's are no problem, but i'm questioning that.
