Youre a long ways away from doing a spring over if youre asking questions like that. If youre dead set on it, you should spend the next few hours reading about soa. Much more to it that moving the perches.
If I were you, id ditch the shackles(after you post a picture of your jeep and them lol) and add a spring lift appropriate to the size tired you want to run. Add a small shackle lift as well.

But yes, youll have to get those as well as many more parts.

Adopt your pets. Don't shop for them.

Stock shackles are 4" long so you have a 1" shackle lift.....

Not the sharpest bulb in the box....

If the shackle are only 6" bolt to bolt then it's not a 4" lift shackle. For it to be a true 6" shackle lift it will be I've 16" long.
Stock ones are 4". A 1" lift shackle would be 6" long. Every 2" longer they are hole to hole the lift is one inch.

As far as the SOA goes I'm not sure how it works on a Sami but on a jeep if you do a SOA with out changing over to a high steer knuckle you will have an issue with components hitting each other and really bad bump steer

Here is my yj with 2.5" springs, .75" shackles and 1" body lift.



It's on a set of 35's right now. With a drop pitman arm I'm almost parallel and that's where they should be. If you look at the threads most people end up not liking those soa's due the steering problems. Now change over to a high steer knuckle and you can do it.

Yes you have to do high steer on sami to. My worry is the drive shafts being long enough so don't fall out if I flex it a bit. Not that florida has many rocks lol. And was just told was 4 in lift. The front shackles are 6inch and rear so guess its just inch lift. Means I need to find were my clearance for 35s come from? Hate to sound stupid but this first jeep. Normally run sami just couldn't pass up.

Check for serial numbers on your springs as well as for a body lift.

Just north of Florida there's plenty of rocks. A 4" lift is right on the border line of needing a sye and cv joint. Post some pics of said jeep. A pic is worth a million inches.

Nah. Those arent 4" lift shackles. If they are only 6" from bolt hole to bolt hole, they are 1" lift shackles. They would be a foot long to give you 4" of lift.

Measure from bolt center to bolt center on your shackles. Subtract 4 then divide the remainder in half. That's how many inches of lift you got from your shackles. Ex 6" bolt to bolt = 1", 8" bolt to bolt" 2" etc etc.
