springs, axles, and swapping?

Hey everybody, i have a yj and i see that people swap out xj leaf's onto their yj. i was wondering if thier a direct swap and what kinda lift do they give. also ive been looking around at axles, i want to do a 350 swap and run 37-40 tires, and i found rockwells for around 500 bucks per 2.5 ton axle. which brings me to my next question why dont you see any under jeeps? and finaly where would i find the 231c, i think it is, to bolt up to the chevy trans? thanks a lot guys

xj leafs are a little longer than yj springs and give about 2" lift IIRC.
I believe the main downfall to rockwells are:
pinion brakes
6.72 gears (no other choices that i know of)
weight
center section usually gets shaved
different bolt pattern
and probably a few other things to add. Not saying it's not a good choice just giving you possible reasons.
Can't help you with the t-case sorry

you cant drive on the street with a pinion brake in most states. Unless you do the disc brake conversion on a Rockwell, (wich cost about $1500 per axle) you are pretty much making your Jeep a trail only rig.

Rockwells are all over the place here, but they are trailer queen rock crawlers that ride on 44"+ tires and usualy have a healthy v8 and run a minimum of 4:1 geared D300's or Stak or Atlass Tcase or something of the like.. Also, most of the guys who wheel them, use 2 steering axles.

TH350 trans or Small Block Chevy 350 CID engine?

If you are looking for a TH350 trans to a NP231 adapter... check with Advanced adapters or Novac Conversion.

the 231 c came behind the 700r4's in s10 blazers and the like.
i dont think they came behind any other tranny (350,400 etc), so it would be counter productive to use in that case. different output shaft on the tranny i believe.
get the t/case that came behind it, and then you could maybe run a passenger side drop front axle (dana 60), which are cheaper than a driver side drop due to everyone wanting them for the jeeps they own......like me!

I'm looking for the 231c as well, and according to everything I've read (which could be wrong, you never know) the right case to get is behind the auto v6 chevy s-10 4x4 from 88 - 92 (?). Snag the tranny too, its a 700r4. If I'm wrong, someone else can correct me.
