Should I be worried?

After reading all the lift reviews and a bit around the forum, I saw mostly negative connotations about the Pro Comp 4" Lift/Suspension Kits; especially the Stage I.

I recently bought a 2012JK and it came with this installed. I'm pretty new to this stuff, please pardon my ignorance. I asked about the resilience of everything (of course) before I bought it and was assured that it was "great" for off-roading. I mean, what's the point of the Jeep if I can't do some serious off-roading?


I've taken it on some light trails so far and everything seemed fine, minus some really annoying squeaking when driving it on the road sometimes.

Now, after hearing what you all have had to say, should I be worried if I try and take this on some difficult trails?

How hard are you planning on off roading your jeep? For what most of us do here, almost any lift is good. When your wheeling party starts regularly breaking components on their jeeps then you might be able to see the differences in lift qualities but if you are just doing trails with some mud and rock crawling, that lift kit will be fine.

Remember, there will always be something better than what you have. If you compare any lift kit to the most expensive custom lifts they won't look as good. If you compare your pro comp to what most people have and the type of stresses you plan to put on it, it will be fine.

the biggest difference between any lifts are the amount of components and the quality, specifically the ride quality. In most cases the difference, all parts being the same, between different quality vendors will be how much the springs sag over time and how quickly the shocks fade. It won't blow up and cause any damage, it just might not last at the desired height as long, or stay comfortable as long

I wouldn't say worried. Concerned might be a better word. Just keep an eye on things and you should be fine.

Can you think of anything specific I should watch out for? (There's probably a thread for that somewhere here though)

So, basically, the "better" the system the less stiff the ride will be and the longer it will last?

well, i think more times than not the coils will be firmer(less prone to sag), it might not always be stiffer or softer. it just means if you buy a 3" lift, even with heavier bumpers and armor, itll stay at it 3", as opposed to a cheap one which might wind up sagging considerably. that being said, I wouldnt worry; unless you dont like how the lift rides, theres no need for concern; if anything the only thing to watch out for would be shock fade. one of the guys I wheeled with has a nicely built rig, and he has the procomp 4" springs, he just got some fox shocks to make it ride the way he wanted on the trail

My main concerns with the procomp stage 1 is that at 4” it doesn’t address the other components that need addressed. At that height you should be running control arms (at least front lowers), considering new driveshafts, front adjustable track bar and with the 2012’s the exhaust extensions. Probably something else I am forgetting. If you haven’t had any problems thus far, then good, but address these and wheel your kit. With additions like steel bumpers and trail armor your springs may sag over time but you can replace those when that time comes.

Are you running 35’s all around? If so you should consider an aftermarket tire carrier if it is currently on your tailgate.

Ah gotcha. Sorry for the horrible replying earlier, I thought it would "thread" my replies to each individual. Lesson learned.

I was actually going to find out about some of this, thanks for the specifics. Since I'm still new to all of this it's nice to know specifics of what to look for. It was all professionally installed so I assumed it was done correctly.

Also great to know! I have both steel in front and back:

Smittybilt XRC Rear Bumper (Hitch and Tire Carrier) PART #76856

I have the same lift as you do, though mine is a 2011 4dr. I installed it about 4 months ago and I'm happy with it. I also went with the MX6 shocks. I also installed this lift on my friends JK (09 ) a yr after he got it. To this day no problems.
As for as control arms go, ya they will be nice to have but from what I've seen on other JK forums these will help out.I'll be getting them soon.

Thanks!

I found out after a quick discussion with the guys who did the work that they actually installed a lot of these options, including the geometry corrections. I caught them at the end of the day so we're going to chat tomorrow about everything they actually did (since only generics were listed on the invoice).

I appreciate all the responses, especially for my first time here. Thanks guys!

I did think of one question, on your JKU did you regear at all?

Was it installed by the dealer or a 4x4 shop, more specifically a Jeep shop? The dealer or 4x4 shop may not know (or care) to address the components I mentioned. The dealer is trying to sell a nice looking Jeep and the 4x4 shop is just selling a lift kit. A shop that does all Jeeps should know to address things at certain heights.

Those AEV brackets are an OK band aid but NOTHING compares to actual control arms. Also your stock arms will hang down further than they are now, so to me that is more chance if snagging up on something when wheeling. I would go for a pair of Rusty’s adjustable control arms, they are only $200 and you have the benefit of being able to completely dial in your caster. Rock Krawler’s arms aren’t that expensive either.

I did not regear. Liveing down here in FL. ( flat lands ) and haveing 4:10 it's ok.

I'm not saying those brackets are better then a set of control arms. From all I've read they do what they are made for and those people who have them are happy with them. And from the looks , they would hang down on more lower then a long arm kit.

To answer your question: installation was done by 4wheelparts. I talked to them and apparently their other representative didn't tell the whole truth. They actually did the bare minimum (when talking directly to the guys and not some generic rep).

So, it took it upon myself to crawl under and take a look. I found some interesting facts.




I see what you mean about the control arms being kind of wussy. I'll have to look into replacing these before I do anything difficult.

I also saw this, what looks like rust. It probably also explains the squealing when I backup and turn left a lot of times (unless I'm mistaken):

Sway bar links don't do much. Strength is not a concern. Bushings go bad and you might get some clanking around.
Disco's can be had for the front to add increased articulation or flex.

Surface rust is fine. Your looks a hell of a lot better than mine does

Those springs sure don't look like they'll compress very much
