Question JKS ACOS Opinions

Right now I have a 4" Teraflex lift that sags a good amount in the rear.
Even with the extended bump stops I'm always getting bad fender flare rub on trails that imo aren't anything bad at all.

#1) I want to correct this problem because it's really limiting me in where I want to take my Jeep, because I fear I'm just going to end up tearing the flares completely off if I'm not really careful.
(that's no fun)

#2) I hate the way it looks when ANY lift sags in the back, and I want this thing riding at least level, or with a bit more height in the rear, loaded or not.

The shops around here tell me just to get new springs.
Well, IMO there's no guarantee that is going to correct the problem in manner I want it to.
And if the fenders still rub, and the rear still sags after I put new springs on it,
I'm going to be even more pissed than I am now, and it will be just a waste of money to me.

So instead of new springs,
I've seriously been considering the JKS ACOS.
That way I can adjust it to MY liking whenever I want.
Is that the wrong way to look at this issue?
Do any of you guys run these, and how do you like them?
What are the pros and cons to these spacers vs new springs?
Would I need any other components to go along with these?


Plus....I want to install a HD Bumper with a Swing Away in the near future.
That's gonna add even more weight, more sag, and probably make me have to buy some other form of leveling kit anyways.
So why not just do this first?

When I swapped my OME suspension from my Tj to Lj I noticed that I wasn't getting the same height that I had on the Tj and really wasn't clearing my 33's so I decided to use spacers. I have the JKS ACOS up front and 1 3/4" daystar rear puck spacers. Been off roading a few times since and they handled it great though I have the front the lowest it can go right now. I don't have any experience with adjusting them just yet. However, quite a few members in the local jeep club that I belong to have been running them for quite some time and love them.

ACOS are nice but pricey.

If I were in your shoes I would add coil spacers in the rear until I added the heavy rear bumper/tire carrier. I would then check into new springs for the rear. If you weren't happy with the height of the new springs you can always add the rear coil spacer back in.

Ive got them front and rear with a 2.5 lift. I just adjusted the front this weekend, after having them bottomed out for 2 years. Adjusting them was not as easy as I thought it would be, mainly because you have to unload the suspension. It requires a serious jack and some really tall jack stands. After I got it unloaded, I still had a rough time turning the adjuster with channel locks. Then I had the bright idea of screwing a 1/4" sheet metal screw in the side of them and they turned pretty easy. In hindsight I would say paint the threads with a good anti-seize, so adjusting them is easier.

They are really handy though. They allowed me to level up front to back, as well as side to side to square her up. I highly recommend them, they are a great piece of kit.

They really should drill the adjuster for some dowel pins and give you a wrench. This would make adjusting them a piece of cake. If they did this it may even allow adjustment without the unloading issue. Im no engineer, but it seems like a good idea.

Yeah, I talked with some local guys about them today.
They said the exact same thing as you're describing,
and that's why they DON'T like them.

I really like the idea of being able to adjust them if I need too,
but if they're gonna lock up like that......I'm really not sure.

I'm running them in the front. Once you get them set the way you like you probably wont be adjusting them again. If you do need to adjust them it is a little difficult but not that big of a deal. It's not like you will be doing it every week. JMHO Robert

I still like them for the ability to adjust them whenever I add some thing or change the weight distribution (ie Hardtop). Also while being a pain, it still only takes about half an hour to adjust them. Plus its like anything else on our Jeeps... adjustable control arms, track-bars, and spring height... it makes the Jeeper in me happy.

Oh, and I have no experience with the newer style. They do seem a little steep.

Yeah, that's why I wouldn't mind having a set.
It would be nice to be able to level everything out when you add/remove things with significant weight.

What do you think about doing this instead of buying new springs to resolve the fender rub, and getting the back end up at least level with the front, if not an inch or so higher to compensate when loaded?
Would I need any other components if I raised the back the minimum 2" of this kit?

Some people say just buy new springs...
but that's not going to guarantee the amount of height I want in the back.
If it didn't raise it enough, I'd still have to buy pucks.
These ACOS kinda seem like you could get it more where you really want it,
the first time.

BUT...I don't think I'd want to do this AND get new Springs.
It's kinda got to be one or the other money wise.
