What about wheel size I want to run either 35 12.50s or 37 12.50s. And every thing I have read says at least 4.5 in back spacing. Is last a common since or what.

You also said - "I want something durable enough to last".

The larger you go (e.g. 37" vs 35"), the more you'll stress the system. There's a whole range of stronger or strengthened parts.
Mileage will increase, steering will be somewhat less "nice".
For the same rim, say 17", and more rubber on the 37" (and 28~30psi for ride comfort), road behavior will suffer. Emergency maneuver 'envelope' will decrease.
Wider tread, too, contributes to reduction in steering feel.
If you're willing to invest some more: Full Traction CRC restored the steering behavior & feel on my '12, and made it even somewhat better than with the stock wheels and no lift. I wish something similar could be done with the front axle...

On '12 models, for 35", 4.1 gearing is the minimum, 4.56 even better.
For 37", the reasonable minimum is 4.56 .
(A step more for '11 models)

I suggest you first gain experience out there, see what's really holding you up -- ground clearance, wheel size, recovery gear -- and then start modifying.

I run a RC 3.5 series 2 lift on my 2012 BFG with auto trans and 3.21 gears. It provides plenty of lift for 35s and with flat fenders you can run 37s. I run 35 inch Nitto Trails on 18x9 XD Misfits 0 offset 5 inch backspacing. No rubbing issuses at all. I also upgraded my LCAs to adjustables to dial in the steering and flightyness it had after the lift. Drive great now and the RC is nice on the pocket book.

Anyone running a BDS KIT? I'm looking at the 3" BDS w/Fox shocks and steering stabilizer and was just utopia as to the quality and ride . Thanks

My setup (for now) is 2.5" teraflex coil lift with shock extensions (gained about 3") plus 1 1/4" rough country body lift, trimmed fenders, pinch seams and cut 2" off rubicon rock rails, stock wheels with spidertrax spacers and 37" bfg km2's
