Yes, Leaf Springs in the rear.
My traction bar came from M.O.R.E.

Hopefully you upgraded your axle. Traction and the Dana 30 axle won't mix well.

Since Novak did the harness you might want to ask them. Otherwise, I'll need to know which ECM/PCM you have. There should be a sticker on it with the Hardware and Service Numbers. PM me the service number and I can tell you which pins and wires you need to tap into for 5V and Low Ref.

Great build! Makes me want to get another Jeep and attempt this!
Getting 8 MPG with my last lifted one left a hole in my pocket at the pumps!
LS motor should get much better mileage not to mention performance than a 4.0!
Heck I'm tempted to put a LS engine in my 08 F-150! Gotta be better than the 11-12 mpg I get now!

I've never checked the mileage. I just enjoy it. However, I can't imagine that it's all that great considering it's shaped like a brick with additional stuff like a winch and four big tires to get in the way of clean aerodynamics.

So here's step one of my plan.....
Split the NP231 Chevy case and my stock NP231 Jeep case and use the Chevy front half and guts with the Jeep back half and output shaft.
From Jeepin1995 on Jeepforum.com here's how to make the hybrid case:
chevy front case half
chevy 4-lo planetaries (they have the correct splines for the chevy trans and have 6 sun gears, not 3 like the jeep case therefore they are stronger)
chevy chain and sprockets (on the main shaft and also the front output shaft) the chevy chain is wider/stronger
jeep rear case half
jeep mainshaft(so i can keep my jeep SYE)
jeep SYE, jeep speedo gear/setup
This hopefully allows me to retain the stock speedometer since the stock sender will still be in place.

thanks for the help. I dont have the SYE so could i just use the whole t case with the chevy slip yoke.

Not sure about forum rules on links to other forums so I sent you a link to the actual page via PM.
The T-case is a late 80's to mid 90's NP231C. If it has that tag on it you should be safe.
The only issue you may run into is the factory adapter between the t-case and trans. At one point I think chevy changed from 5 bolts to 6 bolts at the rear of the 4l60e trans case.

Hello nice read!
Any advice for a guy with a wrangler that has a ls3 and wanting a nv4500 5 speed? Lol I'm trying to find out the best way to install the nv4500 to the ls3

Sorry for the slow response. Just saw this post.
My transfer case is 1/2 Chevy (front) and 1/2 Jeep (rear) so my stock speedo runs off of the stock Jeep Vss on the rear output shaft of the T-case just like it did from the factory.

wiring VSS I did the same thing with the 231. But since I eliminated the stock ECU/harness I am not sure how to wire the VSS to the speedometer. I used your write up extensively with my swap.

Hi Docked,
What was the verdict on your tach. did you have to use a pull up or did the PCM run it ok? I'm in the middle of my swap now so I'm feeling you pain. 4.0 to 5.3. I haven't seen much information for my configuration. I'm the first year for EFI and the last for the VDO gauge package.
Thx.
