Lift and tires for 2012 4-door JKUS

I have been looking on the forum for a while to figure out where to start. I'd like to get a 2.5" to 3" lift and put 33" tires on my JK Unlimited Sport (won't kill gas milage). I just bought it last month and spend most of my time at the beach or on the road so far. Plan to do some light to medium off roading especially during hunting season. Looking for suggestions that won't break the bank but still remain good quality. I plan to use my stock 17" rims as well. If you can think of anything else I will need please advise.

Also do I need to lift for 33" or can I run them as is? Then I can do the lift later.

Do I need spacers for the rims?

Thaks in advance for your suggestions!

-Sam

JKUS? Is that a Sport or a Sahara? Or is it something else? Two Unlimited JK's maybe?

I think it's the USA version JKUS.

A 2.5" lift is nice. Most likely with the lift you'll need spacers or new wheels.

Why the spacers? What will the tires rub without them?

The bolt on the top of the rear sway bar link will be right at the same level as the wheel and depending on how it's positioned it can/will rub. Here's a pic with a TF 2.5" spring lift and stock wheels/tires and no spacer:

Because of the backspacing of the stock wheels, wider tires will rub. It's the width that becomoes an issue not the height. Your other choice is to get aftermarket wheels with 4.5" bs or less.

Thanks for the advice. I plan to put 285/75/R17 BF M/T on my stock rims. How big of a spacer will I need? What is the best 2.5" lift for price. Most of my time will be on the beach or logging roads.

If you want to take a chance you can try installing the lift with the links on the inside of the bar (not the stock position outside of the bar), and you may have enough clearance to not need spacers. My Jeep isn't a DD, so I just ordered the lift and when I installed it I saw I had to use spacers (the hole they drilled on my Jeep wouldn’t allow me to move the link to the inside - plus I figured I should really mount it the stock position). I got Spidertrax 1.5" spacers which I knew wouldn't be my permanent solution as I planned to upgrade to 35s.

I'm sure you'll get lots of opinions on lifts. I like my TF 2.5" spring lift...

Did you get new shocks with your TF 2.5 lift? I am looking at the TF 2.5" lift with the shock adapters so I can still use the stock shocks. Later on I could upgrade to bilsteen 5100. Thoughts?

Also, did you change out your brake lines? I've heard mixed opinions.

I think the Rubicon shocks are fine - I kept them and got the kit that came with the adapters.

Nope, the kit has a relocation bracket for the rear, and with '08s there wasn't any issue up front (unless you get shocks that are too long). I believe I read something about newer Wranglers where you may have to do something up front.

Hopefully someone with a '12 can post up if the brake lines up front need to be adjusted at all - like I said I know the '08 doesn't but read that some have to do something. I'm not sure if they didn't know what they were doing or there was a change by Chrysler...

If you aren't in a hurry then take your time and try to sort things out before you jump in and buy stuff. What I did was wheel the Jeep and found what capabilities I was lacking then made mods to fix the issues. You can guess all day what you may need to change, but until you wheel it in the places you want to go you really won’t know what you need to change (who knows - you may not have to change anything).

Sounds good. I believe that I will start with the TF 2.5" spring lift with shock adapters. Then add the 285/75/R17 BF M/T tires with 1.5" spacers and see what else I need from there. If I have to get better shocks or a brake line mod I can later.
Thanks for the advice.

You can get a set of steel wheels for roughly $20 more than a set of wheel spacers. So unless you are just in love with your stock rims, you might want to consider new wheels instead. It would be cheaper in the long run, especially since a lot of tire shops won't touch your Jeep if it's got spacers installed.

And you can resell a set of wheels a lot easier than a set of spacers, so if you decide to upgrade wheels at a later date, you've got that option. That also gives you the option to go smaller than the stock 17" rim, which will make your tires significantly cheaper. I put 15" wheels on hubby's Rubi. His Mickey T's were $265 each in a 15" wheel size. The same tire for the 17" rims were over $400 each. I don't remember what the price for the 16" size was, but it was somewhere in the middle. Still, much cheaper.

Okay, I did end up giving my wheels and tires away, but x10 on steel wheels. I have Unique steels and am very happy. In black too, w00t!
