ECGS 8.8 rear axle options
kind of a newb here, looking for some advice. i have a 05 TJ that i replaced the rear end last winter (thing blew up, long story), and just did it stock because i found it cheap and had a guy cut me a deal on install. now i'm looking to do the upgrade (have the money and it's better to fix before it breaks) so i'm looking for some advice. there are lots of threads, but i can't find anything comprehensive enough.
i use my jeep as a dd, but occasionally take it out to the mountains and do some light wheeling when camping. i don't do it enough to spend tons of money on exclusively wheeling accessories, so i need to know what is really beneficial to a dd, and what is just extra for extremes...
i'm currently running 33s, so i believe i need 4.56 gears. from what else i've gathered, i don't think i need a locker (don't do that much wheeling) but i think i'll get positraction since it seems helpful and isn't THAT expensive.
what else do i need or should i look into? i think going sye is a bit expensive at this point, but if it would help i'd consider it. don't know much about control arms or shafts or flange/yoke, so advice there would be helpful.
thanks in advance!
