What strength upgrades are available for 242 transfer case?

I like the choices of selections it offers (2wd, 4 Full Time, 4 Part Time, 4 Lo). So I want to keep my 242, but I'd like to make it stronger, if possible.

Is it possible to put a strong chain on a 242 transfer case?

Other strength upgrades available?

There are 3 versions of the 242. If you have the 4.0 then you probably have the NV242J
If you have the 4.7 then you should have the stronger NV242HD (has a thicker chain and gears, same planar gears as the J though)
Then there is the one from the H1 and HMV. It doesn't have the 2wd option but has 6 planar gears vs 3 and the thicker chain and gears.

I've heard they can be swapped around and that they can't. I need to do more research as I want the NV242SHD that people have built where they combined the one from the HMV and the one from the jeep to give all shift options and vastly improved strength.

I have a 4.0 so I guess I have an NV242J. Can it be upgraded or would I need to replace it?

Does the NV242HD from the 4.7 have all the shift options?

Is there source that sells the NV242SHD ready made?

the only difference between the 2 nv242's use by Chrysler is the HD has the thicker chain and sprockets. aas for the modified hmv with the 2wd option, I don't know you'll gave to Google it.

before I forget someone made a 4:1 low option but it weakened the casing to install it so production stopped a long time ago.

I'm not a rockcrawler. I don't like 4:1 low.

I prefer 2.73:1 for Lo.

So I'm in luck.
