Lift Advice is Welcomed Here

Hello!

I have a 2012 Silver Rubicon JK. It is my every day vehicle. I do some off-roading and get into the mud during mud season here in New Mexico. No rock crawling.


I am thinking about a 2.5 lift with 35's on 17x9 inch wheels. A well known retailer is running a special this month.


I like the visability of being higher up(former H2 and F150 owner), but don't want to compromise the street ride or significantly diminish the off road capabilities.


The kit comes with Rubicon Express Budget Spacers, Pro Comp ES 3000's Pro Comp 7036 Wheels, and Pro Comp Extreme All Terrain 35's.


Thoughts, pics, feedback all very much appreciated.


Thx

I also visited the "well known retailer" yesterday and found out about the deal. I couldn't find any information about the 2.5" spacer lift based on the Rubicon Express part numbers on their website or in their catalog. But I did locate an announcement from Rubicon Express announcing the lift. In the announcement they claim that it works for 35" tires although normally a 2.5" would not be enough for 35s so I'm a bit skeptical.

I like the wheels they are using in the deal but I've personally never really cared for the way the ProComp extreme A/Ts look.

The price is excellent because they are basically discounting all the labor to zero but I think that if you planned to do any off-roading then the lift would be the limiting factor.

If you just want to sit up higher on the road for street driving then it is probably the least expensive way to get the Jeep lifted with 35s.

I would honestly look into a coil lift. I started out with the Teraflex Performace leveling kit but within 1000 miles I was upgrading the the Rock Krawler Max Travel kit. Do it right the first time or it will end up costing you more in the long run.

Youre inviting the death wobble demons. Keep that trackbar torqued.

My jeep rides great on 2.5 inches of lift. A little rough but you need a stiff suspension to have fun. Ive had some death wobble problems and lifts definitely invite that demon in.

Lift kits will damage the sides of your seats as well...from getting in and out... i definitely reccomend rock sliders with a step on them to help get in. Even with stock size tires on my jeep, the door sills are at knee level which is kinda ridiculous. But cool.

All 2.5" kits that come with bumpstop extensions will be more the adequate for 35" tires. 35" can be run on stock suspension with flat fenders.

My preference is either the TeraFlex 2.5" complete Budget Boost which will retain factory ride or the TeraFlex 2.5" spring lift which will ride a bit stiffer.

2 urban legends. Lifts don't cause death wobble and you don't need a stiff suspension to have fun.

They are hard on the sides of your seat though!

learn from my mistake. when you pull out those 14mm bolts you can absolutely NOT put them back on your jeep. go buy some fine thread grade 8 9/16 bolts at tractor supply. no need to spend $80 at quadratec for their kit. this is the #1 cause of wobble and steering issues.

get a spring lift, the RK 3.5 flex is only $1300 but I paid much less from AOR here on this forum. spacers are a waste of money if you wheel your jeep, you are just going to install a spring lift and pull those spacers out!

Spacer lift = most do not like it.
2.5" lift is GREAT for 35" tires.
Bottom line = Teraflex 2.5 coil lift....about $450 with shock extensions

First of all I want to thank everyone for their responses! I am new the forum and appreciate the candid feedback. It is very helpful to hear from people that have gone through this process.

Next question (s) will a 2.5 Terraflex Spring lift system accommodate 12 inch wide 33's? Will I need to change out the factory wheels if I go with that tire width?

Also, do I need to get exhaust spacers for a 2012 Rubicon JK with a 2.5 terraflex spring lift?

Thanks all and have a splendid day.

Just Installed this lift 2 days ago on my 2012 you will need wheel spacers if you run your stock wheels ,Im running 1 1/2" spacers on my stock wheels for now. I've heard differant stories on the exhaust spacers I have alot of room with my exhaust so I didnt need them.

Get a good coil lift. I'm getting the Rock Krawler 2.5 X Factor, and installing 35s. I am going to get it done by an experienced installer and weld on the rear trackbar. I hope to not have any wobble issues.

I disagree completely.

First of all, lifts don't "cause" death wobble. I didn't say that. They put additional pressure on trackbar bushings. That's why the axle moves sideways when lifted, and that's why adjustable trackbars exist. You don't think an excessive load on a critical bushing beyond design intentions will make it wear out faster? I am, however, not questioning that stock jeeps can have death wobble as well.

And I completely disagree. I would much prefer a stiff suspension on any vehicle. On sports cars, they handle corners much better. On jeeps they're harder to bottom out, and handle corners better. :P But that's purely an opinion.

I have heard quite a few complaints about spacer lifts due to the harsh ride.

You will need wheel spacers to keep factory wheels with wider tire and with the lift. Can't remember the issue but something rubs on the back.

Tera kits are more complete than re kits, they include provisions for the sway bar end links.

9550's ride very nice and soft, fox shocks firm things up a bit but absorb the jolts much better. Factory shocks are garbage.

If you don't plan to offroad you will likely never have to worry about the exhaust spacer issue. If you plan on wheeling it you will probably have to worry about the spacer.

A spacer on top the coil is not going to make a significant change in ride. It's all in the shocks.

Yes, you can put those tires, but you might as well go with 35's. You can put either sized tire on your factory wheels, though you will need wheel spacers.

No, you won't need exhaust spacers with that lift.

The teraflex 2.5 with shocks is much much much less stiff than factory.

Thanks for all the pics and feedback. Coming down the home stretch on decision making and have a couple of more questions. The set up I am narrowing down to is the following:

1). Teraflex 2.5 suspension kit. http://internationalboardofhypnotherapy.com/locate.html

2). Bilstein 5100 shocks

3). Stock wheels with 33" 10-11.5 inch wide tires.
I am hesitant to go to 35's for reasons of reduction in gas mileage and handling. This is my every day vehicle.

Can anyone provide me with all terrain recommendations. I am not sure which measurement indicates the tire width.

At what point do I need wheel spacers for the set up above?

Also, do I need adapters with the set up above if I get the Bilstein shocks?

Thanks!

Christian

get the exhaust spacer. I have spacers in with a 3.5 and my driveshaft boot is torn from the exhaust. better safe than sorry but you dont NEED it.

they are a pain in the butt to install though. I had to run a ratchet strap from my rear bumper to my Y-Pipe to pull it back far enough to get it on.

Thanks all and have a splendid day.

If you do 12.5" tires on the stock wheels there are many companies out there (Discount Tire/America's Tire included) That will not mount the tire to the wheel because of safety concerns. There are people that run them just fine, but shops can and do refuse installing that combination.

Here is my set up if it helps

1. Tera 2.5 spring lift with 9550 shocks
2. 1.5" rugged ridge wheel spacers
3. 315 70 17 procomp extreme mt2's
4. Super hip flashpaq

My mileage on the freeway in my rubicon is 19 if I stick to 65, which is actually better than stock
The ride is tremendously more smooth (5100's are great but known to be a bit stiff on a dd jk)
The tires have a slight hum but pull nicely offroad and handle very well on road
There is no rub, though I don't have my stupid splash guard under the bumper anymore.

There are no more parts to my set up than that and I highly recommend this or a similar set up.

Thanks for the feedback. Anyone else with an opinion on shocks for a DD JK that is a moderate weekend trail rig. Pro Comps vs Bilsteins vs ?

PS - in combo with a - 2.5" Terraflex lift, 33" (285/70/R17) tires (don't want to re-gear and diminish mpg's) also don't want to chip it yet. Wheel spacers as needed to avoid rubbing, possible exhaust spacers as well.

Blisteins are a great shock, very smooth on the road, tend to stiffen over bigger bumps in the road an also preforming excellent offroad

13 jku 2.5" rock krawler stock mod lift 315 70 17 / GY Duratracs 5100 Bilsteins. I am really happy with this setup. Ride on and off road is great, I prefer it over the stock ride. I do have aftermarket front bumper and warn zeon 10 winch (about 150#over stock) and rear bumper/tire carrier ( 160#over stock) set up helping out the ride. I run the tires at 28 psi and it feels about right. Can't tell about the wear yet though.

I have a jk with the same setup. I have to agree and absolutely love it with zero regrets.
