Hey all. In the coming few weeks I'll be having a mechanic buddy of mine install an OME 2.5" on my 2000 TJ. Earlier this year I upgraded to 31" A/T's in preparation for this lift, and decided that 2.5" and 31's is as far as I'm comfortable going, given my limited mechanical experience, use of the vehicle as a daily driver, and it not requiring many more upgrades or adjustments other than what's included in the kit to do it right.

I know the topic of the OME 2.5" kit has been covered time and again but that's the tricky thing with "just search it"--the more threads that are out there, the more differing opinions there are. So I have a couple questions that will hopefully get me covered as far as everything I need to know, as a relative newbie.

The height:
On Quadratec and other sites, the 2" kit doesn't come with spacers. Just want to confirm that I'll need to purchase these separately to achieve the often talked about 2.5 total inches of lift, and that I'd need a total of four spacers.

The kit:
In short--do I need it? Buying the whole OME kit in one go is appealing to me as someone unfamiliar with the ins and outs of suspension. But I've also seen talk of OME springs with rancho shocks, and so on. Might piecing together my lift be a good way to save some coin on the job while still getting a quality ride? If so, can anyone give me a list of everything I'd need to go 2.5" without spending the full grand on the OME kit?

The springs:
I've pretty much decided on HD. But am open to suggestions as to why I should go light.

The plan:
My buddy is an experienced mechanic and builder with all the tools and equipment I could possibly need for this task and then some. Ironically he's never actually done a lift, but plenty of suspension work. I'm beyond confident that he's up for it but if there are any quirks specific to the TJ or things to look out for when taking this on, I'd love to know (and so would he). I'm not sure if a detailed step-by-step is included with the kit (doubt it) but if someone has one handy and would be willing to link or post, that'd be immensely helpful.

The preparation:
is there anything I ought to do to prepare for the install? Consumables to purchase and use (penetrating oil and the like) on specific parts prior to the job, and so on?

The shakedown:
How do I know it worked? I'll be driving to my hometown 1.5 hours away for a long weekend to have this lift done, and would hate for something to go wrong when I'm halfway through my return trip. What conditions should I cover to make sure everything's in order once the lift is on--make sure I hit highway speed, sharp turns, etc? I'm assuming engaging 4H and 4L is irrelevant.

While we're under there:
Any other components, upgrades, or preventative maintenance I ought to do while the jeep is jacked up and I have access to an expert? Kill two birds with one stone? Sway bar discos?

I think that about covers it. Any help you guys can offer would be massively appreciated. This is probably one of the few chances I'll have to do it affordably for the cost of parts and a case of beer (or two), so I want to make sure I do it right. Obligatory photo of the vehicle in question below, at stock height on 31's.

My first question is what do you plan on doing with the Jeep? Does it get wheeled often? Would 2.5" of lift help vs. say 1" H&R Springs + 4 shocks which would be cheaper and ride almost as good?

I ask because I have 1" H&R springs with Bilstein shocks on mine, and combined with 31s it's great on the street, plenty of tire clearance without looking awkwardly high for the tire size, and not many parts were changed.

Appreciate the perspective! It doesn't get wheeled as much as I'd like, but I plan for more frequency--my brother purchased a 4th Gen 4runner so it's easier for me to have a buddy along now. So for that reason, plus the pure aesthetics angle, I'm pretty much set on this height
 
With your area, you should start hitting the major bolts with penetrating fluid now and a few times until you’re ready to install. It’ll only help in the removal process.
I'll do that! I have a week or two for them to work in the meantime, so that should be helpful

The ome nitro Sport shocks are on par with the Rancho 5000x shocks, but the Rancho are a lot cheaper. Also think about having a complete set of control arm bolts before you start. It's highly likely at least 1 will be unusable by the time you need to reinstall it. Cheap insurance plus the old ones have a lot of years of use on salty PA roads. While some folks have no problem reusing hardware, I'm a bit more cautious when it comes to steering/suspension/ brakes. On any vehicle that sees highway use.

Great point. Do you happen to know the specs of these offhand, or a good place to track TJ hardware specs down?

good to know about the rancho shocks. I just wonder what the process would be to grab all the other parts that are included in the OME kit--are an OME track bar relocator, steering stabilizer, etc. really necessary or can I grab cheaper versions of those parts as well. basically just piecing together a kit that uses OME springs
 
If you're sticking with 31s, why not just install a 1.25" BL for $100 and avoid any other issues and ride problems? Setup pictured in hour one of my lift I installed.

The old OME yellow shocks were great. the newer black "sport" shocks get bad reviews. I have no clue why they changed them and Zone Offroad discontinued their great riding white hydro shocks for the stiff black nitro ones. Oops sorry! In these times of ONLY black lives matter, I retract my comments on how the WHITE hydro shocks and YELLOW Ome shocks were better. WTF happened to this country? Biden=Pussy.

You can easily beat that price on just as good or better parts:

* OME springs ~$350
* Rancho shocks (0-2”) ~$200 (as mentioned, the new OME shocks aren't as good as the previous generation)
* Rear trackbar relocator ~$30
* Whatever bump-stop extensions
* Whatever spacers $30
* Monroe Stabilizer $25

That’s a pretty decent bit of savings, assuming Rancho shocks are available again (there was a supply issue recently due to current world events).

This is really helpful--I've been doing some digging around at what OME spring and Rancho shock combos to use (OME 2933/2942 and rancho rs5000 0-2") and think I've got it settled

but was just wondering about all the supplementary pieces. Came at the perfect time, thank you!

As far as bump stop extensions, is there a specific size I'd need? Assuming with spacers it's just 1/2" to level the rake.

Same goes for stabilizer and relocator - do these vary in dimensions or can I just really go with whatever
 
actually, I'm now seeing that the rs5000 and rs5000x are much different animals. Maybe I need to rethink

EDIT - nevermind, realized that the photo and part numbers specify 5000x shocks, but the item name is 5000x. these are correct.

Could I get away with the above springs and shocks, the OME trackbar bracket (cheapest on quadratec) and monroe stabilizer (https://www.amazon.com/gp/product/B000C53XRK/?tag=wranglerorg-20), plus:

these spacers:
https://www.amazon.com/dp/B001GH5OF2/?tag=wranglerorg-20

these bump-stop extensions:
https://www.quadratec.com/products/16090_1119.htm
For the bump-stop extensions, that's only a pair and I notice that the product photo for the OME kit only shows a pair, but assuming i'd need four total?

With bump stops, you won’t know until you cycle your axles without springs. Basically mount everything up but the springs (include your wheels/tires installed) and do full droop, full stuff each side, and both at the same time and watch for interferences. The big ones are tires rubbing, shocks bottoming out, pulling on brake lines or other tubes, and watching the trackbar Mount on your gas tank.

Gotcha.

So when you say won't know, do you mean won't know if I need them, or won't know what size/thickness I'll need?

I assume the former, since the OME kit just comes with one size and that kit is supposed to be relatively plug-n-play/include all the things you WOULD need (though may not need all)
 
Like @ranger101 said, start hitting that hardware with penetrating oil now if you're doing the lift in the next 2 or 3 weeks. Especially the upper rear shock mount bolts. You can access them pretty easily between the frame and fender liner if your spray can has one of those straws with it. You may need a flashlight to see in there to get the straw in the correct spot.

You definitely want the RS5000x shocks. The regular RS5000 shocks are much stiffer from what I understand.

When I installed mine, I did the rear lift first, then when I installed the front I sit it on the ground to see how it sit. I had a lot of rake. I took the front springs back out and installed an additional upper spring isolator stacked on top of the original. They measure right at 3/4 inch tall and it leveled my Jeep out well. I used the 2933 and 2942 HD springs. My aftermarket bumper, winch plate and winch contributed to the front end sag.
