YJ Springs too much lift

I installed Omix Ada 18201.20 front and 18201.23 rear springs on my CJ7. These are supposed to be stock height but it seem more like a 4" lift to me. Did I get the right springs? FYI tires are 33" but I would prefer to run 31"

For starters; what are those front shackles? They look huge? (And am guessing a big part of your perceived lift)

And you have almost no weight on the springs so far, correct?

I should have explained this in my original post. The front shackles are part of the YJ SUA kit from Rocky Road, it accommodates the wider 2.5" wide springs, and locates the front spring hanger about an inch forward because YJ springs are longer than CJ springs. I redrilled the holes closer together to reduce the amount of lift from the shackle they are about 1" longer than stock. The shackle would only account for about 1/2" of lift since the amount of shackle increase only results in half the lift. The springs are loaded with a 5.3 LS and 4l60e and Dana 300 installed.

Those show to be stock YJ springs, from what I can tell. Not sure your going to get them to set any lower. Looks good in my opinion. I say run it and see how it rides.

I would be interested in what the caster angle is with that setup.

Would you be able to install a Jeep front frame overlay over that Rocky Road spring hanger relocation brackets? I was looking on their website a couple of years ago and really couldn't see the details of the front brackets very close. And also, will the OEM front bumper mount up as well without modifications?

Jim1611 this is not the first one I have done with the rocky road kit, it drives fine with the kit installed. This one has 2.5 lift springs with 36" Super Swampers.

Keith I have a stock bumper here I will try it and let you know.

Without the fender flares on, it makes the wheel wells look more spacious.

My guess is those stock replacement YJ springs will settle some after you finish the Jeep and drive it some. Right now they haven’t been flexed at all, so they are sitting taller than designed. I agree with BB, run it and see what happens.

The stock front bumper fits no issues. The front frame overlay does not fit without trimming around the shackle hanger. I never run the frame overlay, too bad I have thrown so many out over the years. Who knew they would become desirable.

Kennuck- How hard is the Rocky Road kit to install? Did you do the SOA also? Waiting for mine to be shipped. Never done one and was just curious. Thanks

The kit is a pretty easy install. The front shackle hangers require you to drill one additional hole in the frame rail. I did not do a spring over just the shackle hangers and u bolt skids for the wider YJ Springs.

Can you post a picture of the instruction given?

I'm interested in the Rocky Road kit but drilling the OEM frame might not be in the cards for me. And does the factory front bumper able to be mounted back on?
