Question? I have an 04 Jeep that had a 6” lift on it, I’ve already replaced the coil springs with shorter ones and shorter shocks to get down to a 4” lift. I was only able to lower maybe an inch with that. I would like to go lower. If I change out the track bars or control arms would I be able to lower it more? Any help is appreciated.
 
Are the control arms stock?

Do you have a body lift?

Are your track bars adjustable? If they are you might be able yo adjust them, but they will only adjust your axles side-to-side.
 
The springs set the ride height. If you want a lower ride height, then you need springs that will do that.

Take a measurement. Stock was 12" front, 8" rear. Anything more is the lift height.

Need more information. Control arms? Steering up front. What are your bump stops set at? Pics would be helpful.

They are adjustable but their as short as they go they are long arm. No body lift

That ridiculous track bar and brace conglomeration is going to be troublesome. What long arm kit is that?

Could it be the track bar relocation braket

Maybe. That track bar setup was designed to regain some of the factory geometry when lifting it so much. Dropping it back down is going to probably misalign the tb with the drag link possibly causing some bump steer. I couldn't tell you why for sure your 4" springs did not net you a 2" drop, unless the 6" springs that were previously in there actually netted you more than 6". Could you measure the front/rear springs you have in there now and give us an idea. Don't include the factory upper spring isolator in your measurement.

Is this with springs under-load and installed, or removed from Jeep?
 
Also now that your going to 4” you’re going to want to try and get back to factory geometry with that track bar and dropped pitman arm. If not you’ll probably run into some issues. Gotta love fixing previous owners mistakes huh? When I got mine it was all rough country crap and I’ve spent a year getting rid of it.

The front springs ar 16.5” and rear are 12” they did send a new drop bracket for the front I didn’t use because the guy helping me with it said there was no need and I assume he was right he’s done a lot of lifts.

Yeah previous owner built it to be a crawler and never used it. I want it to be a daily driver but be good off road.

So at 4” of lift (where your shooting for right?) there shouldn’t be any drops or adjustment brackets made to any brackets. You should be using the stock pitman arm and stock track bar placement partnered with an adjustable track bar (Currie perrfered by me) and currect steering (currectlync made by Currie again).
