I have a similar set up with GBR 4.11 and truetracs front and rear. Just got back from Moab and there was only one obstacle I could not complete on Hells Revenge. I use mine as a daily drive and found this set up to be the best combination of road and trail capability. You might want to talk to Bill at GBR. He talked me out of overbuilding my set up including not buying HD axles.

 

I just got back from Moab also! However my brand new rear Detroit locker with 4:43 imploded, something defective... had to tow back to Omaha. GBR is replacing, unfortunately I only got one day on the trails and it was hells revenge

 

I just had 4.12’s installed, on 265/75 the rpm’s are higher then I’d like, going to the Interco 34x10.5r16 and hoping it gets me closer to stock

 

Any more pics of Moab?

 

yeah I am getting ready to post my official trip report on my rebuild thread.
