Can I do just a lift?

I'm considering a 2"-2.5" inch lift (Unsure if I'm going to go BB or full lift kit) on my 2012 unlimited but I'm trying to do it at minimal expense so I can afford other mods as well. If I was to do a 2" lift would I have to upgrade on wheels and tires to avoid other problems...would it look dumb without upgrading them? Would I have to upgrade or relocate anything for such a mine lift?

My landlord has his JKU Sahara with standard tires on a 2 inch lift, and it looks smexy. Beauty is in the eyes of the beholder!

Guess it depends what size tires you have stock. They'll probably look tiny after the lift, and your center of gravity might be a bit off if they're the typical itty bitty stockers.

You do know going with a set of 33" tires instead will grant you the same amount of height, if not more, and look substantially better right? 33" will fit on your stock jeep with minimal rub, almost none if you're willing to remove that worthless splash guard under your front bumper. (It makes a pesky noise when turning hard with big tires installed)

You can even just do the leveling kit for something around $150 with the 33's and have basically the same set-up as a vast amount of people on this forum now.

I've got the Rubicon Unlimited...not sure what size the stock tires are though. I might do the leveling kit route since it's my daily driver...I'll do a little flexing here and there but don't see myself having the opportunity to do major offroading for a long while for multiple reasons.

OK, I'm stumped .How does he get 2" of height by adding 1" bigger tires? Even 2 inch bigger tires only gets him an inch more in height, right?

Correct. The Rubicon comes with 32" BFG mud terrains. Putting on 33's is only going to give him a half an inch more ground clearance. But a 2" leveling kit with additional 33" tires is going to be a clearance gain of 2.5" (roughly) for all of about $1500, and thats getting some damn good 33" tires.

The rubicon comes stock with 31" tires. Or at least that's what the metric size comes out to. A 33" tire would give 2" more height bc it's 2" taller.

As an example here's out jkur just like the op has before and after tire install. Notice the difference in height. 3rd photo is after lift. Now try to imagine those stock tires under that lift.

The lift doesn't give as much as the tires do. To prove that point look at the photo of the jkur parked in front of my jku sport which has a 1" taller lift with the same tire size as the jkur. Then the one I took today with gonzobob's next to mine. He's only got a 2 1/2". See the similarity in height? They all have different height lifts. It's the tires.

Lift is opening up the wheel well for a bigger tire. But the tire is the only thing that's bringing the axle higher off the ground.

Would a Rubicon Express 2" BB look goofy with the OEM Rubicon wheels and tires? Would I need spacers?

To clear 35s on my Rubi, I only added a 2.5" Front coil spacer and a 1.75" Rear coil spacer, both Rubicon Express. That cost me about $150 (+ labor). After taking a dremel to the back of the front bumper, there is ZERO rubbing, even at full turn.

I understand, but what they are saying is if it is 2" bigger its 1" inch on each top and bottom of the wheel. So it's only raising 1". To get 2" higher you would need 4" bigger tires. And in the pic at the bottom is on a slope.

I don't know how to say this, but that is not correct. If your tire is increasing in diameter by 2 inches, half of that distance is above the axle and half is below at all times. That means one inch of tire is added below the axle for every two inches of tire size added, gaining one inch of lift across the entire vehicle.

BFG specs list thier 32" MT KM tires (the ones that come stock on the Rubi) as being 32.1" tall.

And as HardSilver said below, when you increase the diameter of the tire by 1", you only increase the radius of the tire by 1/2". Thus, you have to increase the tire height/diameter 2" for every 1" of lift.

Only one of those inches is under the wheel hub. The other inch is just filling out your wheel well. So a 2" taller tire would only give you 1" more height.

You're right. I need to not post when I've spent the day on the trail and come home to a few beers. /face palm.

Well, I haven't noticed any difference with my ride, luckily; as smooth as it was the day I drove it off of the lot.

Others have said that they have had significant differences after lifting and changing out tires - some due to lift, some due to the tires, others due to not getting an alignment after the lift.

If I only lift it 2 inches do I need to extend my sway bars for them to disconnect and work properly?

I was looking at the 2 inch rubicon express spacer system but it doesn't come with the sway bar extensions. Is there a way to by those separate somewhere so my electronic disconnect would work properly and not put stress on it when it was connected.
