RocTrac swap

[Jack'D]

Has anyone (searched 4to1 swap, nothing came up) put a Part time RocTrac 4to1 in their sport, or non Rubicon to replace their 2.7to1?
Computer Issues, aside from the tazer reprogramming?

I did this on mine. The only thing I had to do was change the setting in my flashcal to 4:1 after the swap. The swap was straightforward but time consuming and used the same driveshafts. I did mine in the garage with no lift but I did pick up a transmission jack from harbor freight that helped out a lot. Let me know if you have anymore questions.

Thank you!
I had the dealership instal mine and am having a hard time getting it to play nice using the tazer JL mini

That is weird. I figured the tazer would work even better with changing the settings than my flashcal.
