Whats normal rpms @70 mph?
Im runnin 35s on a 2.5 inch lift on my 2010 jku sport so i assume it has the 3.73s. It was a 1 owner so i doubt they regeared and didnt tell the dealer when it was traded. I dont run a procal yet but i know everyone says their setup and stock gears suck. I dont really think its that bad and ill be purchasing a procal today but i was just seein what the normal rpms for these gears are @ 70 mine were right at 2600 with od off.

actually driving with od on or off should be determined by terrain, speed etc. If it is in od and not hunting or lugging you will be fine. why run at 2600-2800 rpms driving down a flat interstate at 75 when you will be fine at 2200rpm etc. let your vehicle tell you what it needs.
