Hi Everyone, Nice to join this group.
I have a 2005 Manual Transmission TJ Sport with a Dana 30 in the front and Dana 44 in the rear - currently running stock 3.73 gears.
I am on 32" Cooper STT Pros which I deflate to 7psi when riding in the desert (and no - they have never popped off - TJs are light)
I do a lot of big dune desert driving where you need speed and most often I have to be in 4 Low running 4th and 5th gears on the big dunes.
I realize that I am putting excess strain on my drive train and have decided to regear to 4.56 so that I can stay in 4 Hi in the big dunes and not have to resort to 4 Low.
My questions are as follows:
1. Would 4.56 be the right gear ratio for me on 32" tires to maximize the power output from my 4.0 engine?
2. Do I need to change the carrier on the front or rear when I do this gear change?
3. I also want to install air lockers while Im doing the regearing and would like to ask whether the lockers and carrier change are going to be a problem in terms of fitment.
thank you very much!
This video (courtesy of a buddy of mine) will give you an idea of the kind of drives and speeds we do:
