I 100% understand everything with the trackbar. It's more my over height issues. Considering that just 2 pumps on a jack and all it does is lift the truck/wheels off ground. It doesn't compress the suspension at all. I don't see it dropping back down to the 22-22.5" range it's supposed to be at for the 3.5" lift. And yes. Everything is in the correct place.

Everyone that does the F<R swap doesn't have the complaint that I do. I'm certain that will fix my issue. And after returning the rear springs the adj. trackbar can fix my centering issue. Sounds like I'm the only one who has a pickup-ZJ :-/

I used up country coils in the rear with a 1" puck for the front to rear and RE 4.5" coils for the front. It was pretty tight in the rear. I wouldn't do that again though.

Yeah. That's the other thing. I could add a spacer in the front to compensate but I don't like the rake in the stock CA's. Saturday when I thought I had gotten the wrong springs and was contemplating doing the swap, I should've. It always when you don't listen to your gut instinct is when problems like this occur. Thanks again for everyone's input. I've been around many car clubs having a Modded Mustang for 6 years and I must say. Jeepers are way better. No one thinks they are better than anyone. And all they want to do is help other people like me with any issues.

Personally I would do that. Toss a 3/4" spacer in front and get a set of F&R lower arms.

I have that same lift. I installed the springs on the right in the rear. It sits higher, but its similar to the stock rake it had. It sits like that for towing and hauling purposes. When I go camping and load the hell out of my Jeep, it sits level. If you want it level, buy front spacers. I hope to good you upgraded the shocks too. If not, its going to ride like a Sherman tank. Mine does.

take pics of how the jeep sits.

i dont' know what they sent you for rear springs but ZJ rear springs for a 3.5" lift will be identical in height to your stock fronts;

put it this way; the 5.5" lift springs i just sold, there is absolutely no way to mess up which is the front and which is the rear; the rears are 4.5" shorter.

i don't know, but man it sounds like you're having a ***** of a time IRO. seems like its always one guy that has mistakes pile up on them.

My "4.5" IRO coils sit very high in the rear too. i put a 1" spacer in the front and the rear still looks tall. Ill have to measure for curiosity's sake.

Granted they aren't evenly matched up side to side you can tell they are the same height. And for drivability sake ill be happy as hell when I put the factory fronts on the rear. When I drive into my driveway. If I go at it straight, it's so stiff my rear tires hop off the ground and chirp. I already have the return labels ready to send upgraded springs back. And yes. I've had one issue after another and I'm hoping its almost over after I do the swap.

And actually the new springs are about 2" taller than the OE front springs. Which also the factory fronts are a good 2" taller than the rears.... So imagine roughly 4" of added spring in the rear. Um no! Ill take pics of that hopefully tonight after I tear it back apart.

Spring rate affects the springs loaded height. Looking at them out of a vehicle tells you nothing of the ride height. It tells me the left ones are the fronts due to the larger diameter coil. I have the same springs and like them. I do have a heavey rear bumper, sub, tools, 33" spare and high lift in the back. I put them in yesterday and it is at 22". I have all 4 adj. arms and track bar. I got them for $50 new, in the box so I will cope with it.

Doing front to rear is a crapshoot. I did and after 3 years I snapped a coil. I think my 4.0 coils gave me 3". I had a set of upcounty's from a crusty 93 and those were too high and too stiff for my liking, more like 5". Then I put in my old front 89 XJ coils and a 1" spacer. This road smooth, flexed easy, and snapped in 6 months on the other side. Old springs may not last long if you wheel and flex them. Welcome to the world of Jeeps.

After reading this thread I went and measured by IRO "4.5" inch coils and I have 7 INCHES of lift sitting at 25" hub to fender in the rear and 24.5" in front with a half inch spacer to even it out. This is after about 10K miles on these springs. Im currently looking at RE springs to replace these monsters. I dont need that amount of lift.

Yeah. I ended up swapping out the new ones for my OE fronts and it brought it down level to where it should have been in the 1st place. Returned them for a credit towards the adj rear trackbar since axle is still more off center than I would like.
