I just ordered my OME tonight; I will be doing the install myself when it arrives, and I manage a day off from work to get it installed... I will post up my results. But it is sounding to me that you're are not alone, and it might be a non issue when it comes to the way it performs anyways.

 

Those are the 3 inch and up JKS............. at the lowest setting it is almost perfect, not hard to get off or put back on.

I am not sure about the question referring to PKESS3's .... cant picture it in my head i will look again at the pictures

 

Just took mine wheeling for a few minutes, flexed it, and now the front springs are both perfectly vertical. Strange because I've wheeled it many times since the lift, but this is the first time both front springs have been perfect.

 

Tommorrow ill flex her out a bit and see what happens

 

What do I need to get in order to deal with the castor problem that might be causing the springs to be bowed? upper or lower control arms, or both?

If its within $200 I might give it a try


ARB said it could be the track bar too...... said the 'system' was not designed to be used with after market track bar

The rear has a track bar bracket, but retains the factory bar. EDIT: I am using the FT bar but ARB told me that the rear should be used with a bracket and wasnt really designed to be used with the bar, although they yeild the same results so I dont see why it would matter, and why would you need to center your axle in the rear but not hte front? That dont make sense to me

 

One clarification. I didn't say that OME lifts have a bow in them. I've seen several different kits that have a bow in them. I don't think that this is an OME specific issue. The more I think about it, I don't know that there is an issue with this at all.

I wouldn't trust what ARB tells you. In reality there's most likely less than 10 people in the whole world (OME design team) who could really provide the answers that you're looking for. I'm assuming that the question would be, "are these springs supposed to bow out a bit?". The reason that I say don't trust ARB, is that an adjustable track bar can be adjusted to match the factory setting. To say that an adjustable track bar is causing the issue, is simply incorrect. And I know that you've tried different settings with your track bar.
I'm assuming that you have the HD lift. If so, is your lift at only 2"? Remember that's what the kit is designed for. Unless you have a large (ARB style) bumper and a heavy winch, you're not even running the lift the way that it was designed to be run. Might that be causing the bow?

To adjust castor, you need adjustable upper control arms. Lowers are used to adjust the wheel position. I'd say don't waste any more time or money by installing new uppers. First decide if you can live with the bow. If you can, then try new uppers, knowing that it MIGHT help. Oh, and adjusting the caster in order to get your springs straight, is a terrible idea.

I still say keep the lift and enjoy. Really the only problem that you've had is cosmetic at this point.
Have you looked to see if you have the dent behind the passenger side lower door hinge? That one will make some of the old-timers laugh

 

I am running the light load up front due to the light bumper and small winch.....was recommended to me by northridge.... constant about 120 pds give or take a few for me, and the light is 0-150 if i rem correctly

right now I think I got about 3 inches(this might settle?)............... but it shouldnt be because I picked to stiff of a spring for what I am using it for/with........... if it is then I think that is false advertisement on OME's part

Your right, the only thing so far is the way it looks is bothering me.... and yeah After spending as much money as I have on it, Ill keep it alright, hopefully something will come along to allow me to correct the problem or it will correct itself

 

If it's bowing because the springs too heavy. Too light possibly. I'm sorry Woods, but I must disagree on adjustable control arms being a waste of money. The OME lists itself as a 2" lift, but most of us are topping out over that magical 3 inches where extra adjustments are desirable.
I sure wish I had that 2 cents everyone is putting in on this thread..... I could buy a regular cup of coffee...at some cheap dive.

 

i just installed the OME lift on my 08 Rubicon and i dont have any bowing i didnt do any track bars or anyting i also have the medium springs and stock bumper and no winch.

I know what you mean about it just doesnt look right, i freak out the same way even if it still works right it still has to look right as well

 

Congrats! You guys got me all kinds of crazy when I started to read this thread! Which caused to me to race out to the garage and make sure nothing silly was going on with my OME lift. My springs aren't bowing, but the gap between the outboard bottom of the spring and the lower perch seems normal to me. Just curious, but did all of you who have the bowing issue install the .5" spacers on your front springs? One more quick point, Dave at Northridge is right about those rubber isolators at the top of each front spring. If your springs jumps that isolator or crushes it during install and sits like that unnoticed, the spring will eventually/naturally develop a slight bow.
