Thank you all in advance for your input.

I have an '07 JKU. 3.8 6 speed.
When I bought it, it had what I believe to be a 3" budget boost and 37" m/t's. I added 1.5" spacers. My thought is to rip out everything the last owner put in.

Based on all the videos and research I've been doing here on the forum - This may not be a good combo as the camber could be off, as well as the added wear and tear on the drive shafts. Im not feeling anything rumbling or anything when I drive it, and it goes up and down the road pretty nice, but also dont want to be tearing stuff up.

I - do not like the bb.
I - don't necessarily need to stay with 37's, although I've gotten use to the look and like it. Also, I've got another year or so on these tires.

I was planning on pulling the bb off and doing a 3" lift, although I'm reading that's also not the best option for 37's. Most say 4" for 37's.

Q - Is there anything to do with the current bb that makes sense? Perhaps a 2" lift with the 3" bb? Does that make sense? Or do I look at doing just a spring lift?

Most of my time is spent on pavement though I do trail ride. There are some obstacles at the places that I'd like to attempt, I just dont think I have the ground clearance for it.

It is my DD, but I only drive a mile to work. I watched this video that someone put up, which I thought was great. Accordning to the video, I should be looking at a 4" lift, but that gets me in to driveshafts and such, which I'd like to avoid.

TeraFlex Tech: Choosing a Lift for your Jeep - YouTube

It offers some good ideas, but I was looking for some feedback from you all. There are a ton of options and the more I research, the more mind boggling it gets.

I know this:

I like the look of 37's, but dont hate 35's.
15% off road play.
I dont want so much lift that I have to start adjusting and welding to correct my drive line.
at some point, I'll look to add aftermarket front and rear bumpers, which I know can be added weight, which plays a role.

I should also add- I have....somewhat of a budget. I'd like to keep it under......$650-700 if possible.

 

2.5" coil spring lift - rock krawler or AEV

35"s- lighter, better mpg, less wear on jeep

 

And keep the 3" bb- or dump it?

 

If you follow the last poster's suggestions, (get a 2.5 lift from AEV/Teraflex/RK etc.), then you would dump the BB assuming you went to 35's. However, if you want to to save money (tires are expensive!), then just get the lift, and chop your fenders into flat ones. Or, if you do want to spend a bit more cash, then buy new flat fender flares. Either way, you'll be happy.

Though, since you're used to the 37's, if I were you, I would just lift 2.5" with teraflex, cut those stock fenders, and save up for new ones. Not to mention gussetting your axles.

 

I think flat fenders will be in the works at some point. I love look.

Fuel economy....eh....important, but because of my fortunate short commute, I have some flexibility here.

I do however worry about the wear and tear on the Jeep with the 37's.

So, would you say a coil spring lift over a suspension lift w/ shocks?

 

Find out exactly what BB you have in it! Just go and measure it ( pucks). If you want to run 37 then decide to do it right. Get adjustable controls arms , trackbar, new driveshafts ( if needed) some of these parts may have been swapped out already, and you'll be able to use them. Or just buy a complete kit. You may have to go to flat fenders if you don't have enough cleareance, but that can be done later on. Thereis not much that you can do with the old BB, sell it off, that's about it. As for name brands, well that is up to you, buy the best kit that you can find in your price range.
If your happy with the way it drives/handles why get rid of the BB?
For your first question, if you want a 4" lift do a coil, you'll be into it for the sale kind of mines I you do a 2.5" and your BB as the controls arms will be the wrong length for that height. What ever is need for a 4" lift is need if you accomplish it with coils and BB or just coils.

 

They are the same, just different termanology

 

I measured the pucks, they're a 3". He just didnt change the springs. Im assuming he must have done the control arms though. Im good with going to flat fenders.
The reason to get rid of the bb is that it's a damn rough ride on the trails, and I have 0 flex in the suspension. The shocks are aftermarket, fronts unknown, rears are skyjackers.
I'd prefer Not to do a 4" lift to be honest.

Again....also not objective to the 35's. They're considerably cheaper vs. 37's. I guess Im wondering, if I remove the 3"bb, install a 3" coil or suspension lift, should I also be doing something with the driveshafts to keep them from going bad?

I cant weld, so I need to avoid getting myself in to a situation where i might need to.

 

Do you see why I kept my response so brief? This topic can quickly go 80 different directions, with 110 different opinions. Given the information you provided, my recommendation is to start over from scratch, do things correctly for what you do, and how you do it. You will minimize any problems or concerns if you utilize KISS planning. BTW, dump the pucks!

 

X2!!! He can also use the search function as this topic has been discussed to death. It's even the the FAQ's! Simple....if you want to do things "right" follow the advice from the video ot the FAQ's. If you want to cheat, go read the thoudands of posts out there about people running 37's. There is one from yesterday about running 37's with a 2" lift. It can be done. Just need to do some cutting. The 35 vs 37 debate has also been done to death. The little tiny ground clearance you gain needs to be compared against the wear and tear of running bigger tires.

And comparing a budget boost to a true coils lift is apples to oranges. One gives you the look. The other gives you the look and performance. If you wheel....a budget boost is a waste of money imo.
