Transfer Case Question - Conflicting Reports

[Bushwick18]

Need some helping trying to figure out the low gear ratio on my JL Sahara with Selectrac. Conflicting reports on whether the MP3022 TC is 2.72 or 4.0.

I called my dealership with my vin and they said that info is not listed. I’ve heard through people it’s 2.72 but sites like Extreme terrain tells me this

“Sahara model Wranglers can be upgraded from the NV241 to an MP3022 'Select-Trac' unit, which is a full time transfer case featuring 2WD, 4WD high, neutral and 4WD low. Like the NV241OR, the MP3022 has a 4.0:1 low range gear ratio.”

Anyone have factual insight here? Would be much appreciated.

Only Rubicons come with a 4:1 transfer case. You definitely have a 2.72:1 low range in your Sahara. There are no conflicting reports, Extreme Terrain is just wrong. The new Rubicons are available with Select-trac that includes a 4:1 low gear, but it is not available on Sahara models.

4:1 rocks big time.
