So I have read through alot of 2012 lift questions but most seem too wander around as well as approach things from a well it should be a problem but fix it when it breaks. I would prefer to do it all correctly now and not before i cause it to break. Originally I wanted to go with a 3" new spring lift type kit but it sounds like just too many headaches associated with this. That being said I want to go with a small lift like the 2.5" teraflex coli spring lift for out 2012 JKU Sahara. Keeping the stock tire size for now. The jeep is mostly a mall crawler with a couple mild jeep jamboree type events per year. My understanding is to go with something like a 2.5 Teraflex BB but keep the original shocks to help limit travel and avoid alot of problems.

Questions on going with the spring lift method:
1) Although keeping the original shocks should limit the travel should I still do the exhaust spacers or new y-pipe to be safe?
2) Although the lift shouldnt be a problem is it worth the investment in the new drive shaft for the increased angle and avoid a potential problem?
3) Should i replace the front track bar or anything else to be solid? I have had the death wobble on our 2007 JKU and a 2006 RAM 3500 and that shit scares the crap out you so i would rather avoid it to begin with then fix it after it happens.

Thanks in adance for the clairifcations.

 

I should mention i was thinking about chaning the bumper to teh AEV one used on the MW3 jeeps.

 

Bump bump?

 

Death wobble should be fixed with a good alignment and adj. track bar.<--there are threads on that subject on this forum. Everything else I won't comment on because I am not sure

 

If your only going 2.5" you can get away with the TF spacer kit just fine without needing a new front drive shaft...TF has a great video on youtube for the spacer install and clearly shows what kind of clearance you get and the angle of the drive shaft at the pinion.

 

I also have a 2012 JKU Sahara. I went the TF exhaust spacer route....you will need them or a Y-pipe with any type of lift. The exhaust cross tube will just not let the front DS clear otherwise.
Don't go with a spacer lift. You still get stuck with the crappy factory springs and shocks. I went with the TF 2.5" coils and Bilstein 5100s from Northridge at an awesome price. The TF kit comes with a new rear trackbar relocation bracket and rear brake line drop brackets. I could not be more pleased with the off road performance. On road and hwy performance are better than stock.

IF YOU WHEEL:

You will need to figure out something for your front brake lines. I was able to undo the front brackets from their mount underneath the spring pad and bend the mounting plate loose from the brake line. I then zip tied the lines to the shock body for added travel. I also have front JKS disconnects which I have chosen not to use on the trail yet. The reason is my front drive shaft. Sitting in my driveway after the lift has been done the front DS is maxed out. Any more droop and it will tear the CV boot on the transfer case end. I have $330 saved towards a new front DS and plan on getting a Coast in the next couple of weeks. (By the way....I wheel the sh!t out of mine with stock 32s still, 33s coming soon either BFG KO or GY Duratracs )

One more thing. I didn't want to have to spend a flipping fortune on this lift as this is my first Jeep. So to correct any caster issues I most likely had in the front....instead of going with adjustable control arms, I opted for the Rough Country control arm relocation brackets for the front. AEV also makes a kit for this. I feel absolutely no adverse effects from this lift.

My rig feels solid as a rock on the road and a beast off road. I walk up sh!t that other TJs and YJs have to be locked front and rear to do. After I re-gear to 4.10s/4.56s and put lockers on......SAHARACON letters go on both sides of the hood.
