got pics of your rig??? just curious
what kind of wheeling are you doing, or WHY do you want to go bigger???
and you definitely need to go back to your jeep and upgrade the rest before you think about anymore lift mods.
stock gears with 35's will do some SERIOUS damage to the tranny. i know. i blew up mine on 33's because i pushed it without gears. but i knew that would happen.
i don't remember if you said you had a slip yoke eliminator, but you definitely need one of those.
blocks are a BAD BAD BAD idea. specially at that height. 1"-2" might be ok, but does do more damage than good. i can't even imagine how pissed your springs are at you right now for using such big blocks.
i would recommend taking it back down to the rubicon express 5.5" lift and finish building the rest of the jeep. get some gears to match your tires, make sure your steering is up to par. maybe do a disc brake conversion which will be much more usefull and "cool" than such crazy heights. save up for some long arms like your bro said, and learn how to pick a good line when wheeling.
my cherokee is sitting at 5" lift right now with 33's. then maybe after i put my 4.88 gears in it, i will go to 35's or 37's.
you should really listen to your bro. i'm sure he's got a little more thought into this since he's been there before you. if you are trying to impress or show up your big bro, then do it by pure driving and wheeling skills, NOT with height.
trust me, it won't be so "cool" when you show up with 4feet of lift and break 5minutes into the trail and you bro with is "little" jeep has to let you ride shotgun for the rest of the day.
and for the guys on here giving him nothing but crap. hey give the guy a brake. he's a kid and he's young dumb and full of cum just like we all once were. when i first got into offroading, i never saw the little guy that could, but the BIG TRUCKS with the BIG TIRES that JUST LOOKED COOL. so when i first got my 4x4, that's all i wanted. then after lots of internet reading, working on my own rigs and lots of trail riding, my priorities "naturally rearanged" themselves. i'm sure after he puts his first rock through his tranny pan or can't get over a little ledge cuz he doesn't have the right gears or locker, he'll start to understand if he doesn't listen to what people tell him. i know for a fact that not all of us started building our rigs the right way the first time.
