Regearing NP242 (deeper) in low range??

Can the np242 be regeard deeper in low range?
I am awear of the atlas transfer case.
I have looked and not read about anyone regearing 4 low in a NP242. I ask as my Auto XJ can go 60km/hr in 4 low part time, I would gladly trade 20KM/HR of that top end speed for a lower (deeper) final drive ratio.
any idears?

Nobody offers deeper gearing for the 242. There is a 4:1 kit for 231's, but the thing I dont like about them is the restrictions of how fast you can go with them in low range. If you're looking to go deeper in the t-case, look at the 241OR out of a Rubicon. They are bolt in and a cheaper alternative then an Atlas or Stak or building a D300.
