242J vs. 242J Police / Export

I'm doing a transfer case swap & my 2001 Sport, it has a 231J. I'm taking the 231J out & I have a 242J. I believe the 242J I have is a Police / Export transfer case. I'm trying to figure out if I actually have a 242J Police / Export transfer case.

How do I know if I have a normal 242J or a 242J Police / Export model???

A recent Gallup public opinion poll shows the NRA, at 58% approval, has a higher approval rating than either Hillary Clinton or Barack Obama.

Allpar gives an overview-

Part number shows that chain may no longer be available-

I suspect that chain may be heavier and wider....gears also.....may want to check for future availability before installing.

I assumed the chain is stronger. I don't understand how one tooth design is better than another with this set up......

https://www.novak-adapt.com/catalog/..._242_parts.htm

I thought I saw a website some where that the planetary gears were stronger, but I might be confusing that with a 242-HD. In fact, I was under the impression the Police / Export was a Heavy Duty version. But, I believe I am mistaken with that assumption.

Can I also assume all XJ's sent to Canada with a 242J fall into the "Export" category?

Was the "Police Package" an attemp to use extra Mopar stock & charge a higher price for a 242 transfer case package???

It's not the chain link count - what makes a heavy duty chain is the difference in it's width. As far as I know, all XJs shipped with the narrow chain. Only Jeeps with a wide chain (1.25") are 249s behind the ZJ 5.9 (5.2s and 4.0s that shipped with a 249 IIRC use the narrower chain), 241OR cases behind the TJ/JK rubicons, and some of the WJs with the 242HD.

Round Pin vs. Rocker Joint

http://www.atraonline.com/gears/1997.../gaug97p69.htm


From what I gather, the Rocker Joint is more efficient. The Rocker Joint is apparently found in the Police / Export XJ package of the 242J transfer case.

Heavy duty transfer cases use a wider chain. Both chain styles have been used on the NP/NV transfer cases (round pin and rocker joint), but none of the heavy duty cases have a narrow chain. I've never seen an XJ with a wide chain, but I've seen both chain styles.

My both previous XJs were export models with a 242, and my niner is a ZG built in Graz, Austria. ZJ had a wide chain in it's 249, both XJs had a narrow chain. All using rocker joint design.
