I've had my eye on the Dynatrac or Mopar BBK already, thanks for the suggestion. Have also been looking at the drag link flip kits as well as utilizing the RHD JK drag link and the Synergy insert. Thanks for the pertinent responses so far.
I can appreciate everyone's responses in regards to brand of lift but I have spoken with plenty of people who are happy with their RC lifts and have ridden in and driven my girlfriend's. The only reason I have even considered a long arm kit is for superior road comfort, absolutely no other reason. If I were mainly concerned with off-road performance I would build another SAS Ranger. Price isn't the driving factor guys, my personal experience is.
To clear some things up that apparently weren't clear in my initial post, and no disrespect is intended, however I may be new to Jeep ownership but not to 4wd's. I have a pretty good understanding of most of what I am asking about from first hand experience. I have also been reading this forum and about 4 others for several weeks prior to asking for first hand experience.
I will be running 35's, not 37's initially. I may at some point decide that I want 37's. I was leaning towards Trail Grapplers as I have ran these in several sizes on 1/2 ton and 3/4 ton trucks since they were introduced. I have been impressed so far with the Atturo tires on my gf's Jeep though, so much so they are in serious contention at this point.
I want to keep the factory wheels because I like them. It's not a cost issue, it's an appearance issue. My concern with them is tread wear if they are just too narrow. Never had an issue with 8" wide wheels in the past so didn't think the additional 1/2" would cause a major issue but wanted to hear some first hand experience.
I have read extensively on the supercharger kits. Adding that much power absolutely changes the situation as far as it applies to axle ratio. If a stock motor turns 37's with 5.13 gears they are not needed with a SC added, you would be wasting fuel by over revving the motor for the needed speed. I didn't regear my Super Duty with 40's because it had the power to turn the tires with ease. MPGs went up in town, down on the interstate. Adding that much power to the JK will result in the same scenario, it won't need those gears to turn the tires so regearing will result in the motor running at a higher RPM at the same rate of speed. However, the possibility of this being installed is very slim.
This is not a DD, i have a company truck so it may see 10,000 miles a year. I may tow my boat a half dozen times of year when I decide to pull it out of the marina to take to another lake or Florida. Several weeks to go before delivery. Thanks again.
