Unpopular opinion: 4.56 with 37" tires on beadlocks on my 2 door 6 speed.
Feels like stock. 6th gear is still very usable, and I'm right around 2200-2300 RPM @ 70mph in 6th gear. Rubi t-case still keeps it very wheelable.
Am I an idiot? Yeah, should've gone 4.88 the first time around...buuuttttt sometimes 1st gear is far too short, so it reinforces my bias that 4.56 is fine.
Don't go 5.13's if it's not a trail rig. You'll be sacrificing drivability and have some poor highway performance (unless you drive the speed limit, then you won't have a problem). This is very subjective though. Best thing you can do is hop in some Jeeps (any clubs or buddies around?) and see for yourself. My buddy loved 5.13's. I test drove his Jeep, and hated it (1st and 2nd gear were way too deep to be drivable IMO).
Definitely don't go 4.56. That wasn't my intention with this post.
2015 JK- trussed and locked 44's, 37's, beadlocks, Synergy/Metalcloak control arms, Genright, Warn, Crawler Conceptz, Poison Spyder...blah blah blah
