Jk 33's with a 2.5"lift?

This probably a FAQ but My jeep has 33" Mickey thompson tires (12.5) with 17 inch rims, should I put a 2.5 inch lift on it? I have a steering stabilizer on it and I am pretty sure it has correct backspaceing so would I need anything else?

I have 33 with a 2" lift, and it works find but had to make sure the camber was good, initially had a problem with the death wobble.

I am installing a 2.5" lift this week and running 285/75/17s with spacers. The only other thing that was recommended to me was an adjustable trackbar. Some have said to go without it first and see how it is and other indicated it's a good idea.

I am new as well and now going broke after reading this stuff Check out the largest tire thread on a JK page 4-5. Some guys were kind enough to walk me through this. It has to do with centering on the axle. If you read it i=should help. 4fit started it and it is very good info.

Firs of all, you stock steering stabilizer is as good as any aftermarket version. If you've already bought an aftermarket one, no biggie, but you could've spent that $$ somewhere else. And don't buy one of the dual ss's...they can actually cause problems with your Jeep.

If your 33's aren't currently rubbing anywhere (steering stops, air dam, etc) then you've probably got wheels with good backspacing. I'd recommend 4.5" bs or less to run a lift with new sway bar links.

The only problem you'll encounter with your 33's will be rubbing the fenders if you go off-road, especially if you disco your swaybars. To prevent that from happening, you can add something as inexpensive as a TeraFlex leveling kit ($130), which will give you 2" in front (4 1" spacers) and 1" in rear (2 1" spacers) and will eliminate your Jeep's rake.

A 2.5" coil lift will do essentially the same thing, but give you stiffer, longer coils that will sag less than your stock springs if you buy some heavy add-ons like bumpers, winch, etc.

Next step up would be a 2.5" coil lift with shocks...generally about $800. If you buy a good one (TeraFlex, Rock Krawler, Old Man Emu (OME)) you'll get a stiffer ride, your Jeep will be more stable in corners, and it will handle the rigors of off-roading better.

DW is not caused by poor camber. Camber is the angle of your steering, as viewed from the side, in relation to the steering's pivot axis. On your Jeep you generally want a caster of ~ +4º to +5º. If your caster is off, your Jeep's steering will feel flighty, or twitchy (requiring constant correction) at speed on the highway.

DW is often a result of an improperly-installed lift. It's usually caused when the installer doesn't correctly torque the track bar and control arms, or torques the bolts to same while the Jeep is in the air, thereby causing the bushings to bind.

True DW will render your Jeep undriveable. The only way to stop it is to park the Jeep. Here's a thread that deals with the causes (and the causes of other problems that many people mistake for DW). There's a video of DW in there, as well...

None of the 2.5" lifts I'm aware of come with adjustable track bars or adjustable control arms. They're often not needed for lifts that size.

The only function of an adjustable track bar is to recenter your axle if it gets off-center from the lift install. The function of adjustable control arms is to adjust your Jeep's caster...if you install a 2.5" lift and your caster is off, you need only a set of lower, front adjustable ca's to fix it.

My advice is to install your lift, drive your Jeep for awhile, THEN decide if you need to spend the $$ on an adjustable tb or adjustable ca's. You'll be able to tell if your axle is off-center just by looking at your Jeep head- or tail-on. Even if it's off, it won't affect your Jeep adversely...but most peeps can't stand it being a little off.

See the description above about caster, and how it'll affect your Jeep...

Here's the thread you referred to: Largest tire on stock JK? Here's your answer!

Is the rough country 2.5" coil lift with shocks a good one?

I did some research (read alot of links and talked to a bunch of people) and I think most are good. I went with a 2.5" Teraflex and Blistien shocks from Northridge 4x4. I also purchased 1.5" spidertrax spacers.

Both are very good.

There are several clubs. I haven't hooked up with any of em yet, mainly cuz I do a lot of traveling and my schedule is f*****.

Here's a link to some of the clubs in WI: 4x4 Clubs Of the U.S.

There's also the Wisconsin Off-Highway Vehicle Association (WOHVA). You can check them out here: WI Wheeling Information

And there are sometimes posts about get-togethers, etc, in the Wisconsin section of WF (scroll to bottom of main WF page).

You're correct Clemeit. I have Skyjacker shocks and steering stabilizer and if you don't wipe em down every so often and hit them with wd40 or I use spray wax, they will rust like a mo-fo.

How often do you use the WD-40 on them because I have one of their steering stabilizers.

About every 3 weeks. I stopped using the WD40 because it was degrading the skyjacker sticker (tried to peel it off but gave up when it would't come off in one peice) and the WD40 also caused dirt and road grime to accumulate on the white shock housing. Found the spray wax was the best way to go. It replels dirt and water and have had little to no additional corrosion.

Is it worth installing the kit myself? Or should I just pay someone who knows how do do it? And how much would that cost?

I did mine myself. I did a Black Diamond 2" spacer lift and skyjacker shocks. I had my nephew help me. Took about 4 hrs. Changing springs, if you decided to go that route, would also not be anymore difficult. Now if your changing and upgrading and adding control arms, adjustable tracbars and swaybar links with your lift, that will be getting a bit more involved but still do-able with average skills.
It's actually fun and it allows you to get down to the nuts and bolts knowledge of your vehicle should you have a problem when you're on the trail. There's lots of instructions and videos online to help your preparation.

I want to try it myself, I just don't really have the jacks to lift it up and I don't want to get halfway and not be able to finish.

I used the scissor jack that comes with our jeeps. Bought some jack stands at harbor freight. ProjectJK.com has a good write up with instructions and pictures for the Teraflex 2.5 spacer lift with shocks. Go there and click the "write ups" tab and see if it looks like something you could handle. If not, just pay to have it done. Labor will run you around $150 for a basic lift.
I used to be pretty much an oil change, do a tune up kind of guy. The lift was my first "big project". So if a knuckle head like me can do it, then anybody with basic mechanical skills can too . I just followed the instructions.

Thanks for the help. Do you think that the teraflex is better than the rough country for the 2.5" lifts?

Dirty DOG nice job man self installed i was thinkn of it but i saw my boy do a F150 and it scared my $hit le$$ so i didnt attempt.. they are still raggin on me for @itchin out LOL....

Teraflex has been great as far as CS.

Leveling issue- sent me rear spacers.
Upgraded rear TB bracket it newer kits-they just sent me the upgraded bracket to replace the old one.

$200 new FREE

I run a few RC parts, but Teraflex is by far a better quality product.
I personally like Skyjackers suspension parts. Quality is very good, priced reasonably and I believe their stuff is made in USA.
I recently saw that Skyjacker's put out quick disconnect swaybar links for JKs. I sent back the pair of RC discos that i had sitting for a few months on my workbench, happy that I never got around to installing them. $50 extra bucks for the Skyjackers, but worth the upgrade.

Only bad thing I read about SJ is their bushings going bad.
Don't know if that is something they fixed?

I'm not sure Kjeeper, They are using urethane bushings. I've had mine on for 2 yrs and inspect the underworkings routinely and have not noticed any degradation of the the shock bushings. Plus that's kind of why i stopped spraying WD40 for corrosion, not sure what effect that has on the urethane. But, so far so good.
