NP231 Wide Chain kit

I'm about to TeraLow and do a SYE on my NP231 for my '94 YJ. Right now, my chain is about to go and I was looking into the wide chain kit. I can get a normal chain for $80. I found the wide chain kit for $250. I can't seem to find much information on the kit however. I thought JB Conversions made it but can't seem to find it on their site. Does anyone have any info or have it. Is it worth the extra $150+ for the kit?

Any help is appreciated.

Re: NP231 Wide Chain kit

It is more than just the chain, it is also the sprockets. They come in the 231dhd and 242hd t-cases. the hd means heavy duty. If you look at NP's web site, there isn't that much difference in torque values between the 2. They also have 6 planetairies instead of 3.

I wouldn't waste my time and money building a 231 with a 4-1 set and short shaft kit. It would be cheaper, stronger, and shorter to pick up a Dana 300, 4-1 kit and a back east flip kit.

Yeah dorfs is right exept if your transfer case came behind a stock 4cyl, then the output shaft isnt 23 spline its 21, making a dana 300 not fit, you could find a older nv or different np to fit it....good luck

Re: NP231 Wide Chain kit

All autos have 23 spline. I thought about Dana 300 but instead of flip kit get passenger drop axle.

If I would have had more time I would haev gone that way, but this is my DD and I had already got the TeraLow. And now that I am adding up the prices of SYE, chain, TeraLow, it is coming very close to the price of an Atlas II 3.8.
