Need help on TJ suspension

Time to help an newbie if you will please. I have what I believe to be an older Skyjacker 2.5 kit on my 97 TJ. I know it replaced the arms, coils, and dropped the transfer case. It also has discos but I am not sure if they were part or that kit. I need to replace the 31's and was going to buy a bigger KM2's to replace the worn Truxus M/T's. My question is can I thrown coil spacers on top of my Skyjacker lift? I do not want a body lift and I cant think of any reason why I cant but thats why I came to the professionals. I dont want a SYE, new brake lines or anything like that. Im looking for maybe another 1.5 inches and I want to run 32's. Could someone steer me in the right direction please for my DD TJ!

You should be able to run 32's now I have a 2 1/4 lift and i'm running 32's .

Yes you can add spacers but you will be pusing the limits with brake lines , sye, track bars , every jeep is differnt so it's hard to say

I did a 3.25" lift with no thought about brake line or SYE. I think its 4" when that becomes something you have to look into compensating for. You may want to adjust your track bar but if the original work was done right there may be no noticeable difference.
But like T2000J says you should be able to run 32s as is but you might want to look into some different bumpstops

Nice choice on tires btw

When I bought my Jeep it had 2" BB and was running 32's. If you add 2" on top of the 2.5" you already have you will hit that size that other problems are very likely. Like mentioned earlier every Jeep is different but with 4+" of lift you very well could have issues with track bars, sway bars, brake lines, sye.
I bet you could just add 3/4" spacer to what you have since they may have sagged a bit and be able to clear 32's.

I am thinking I have some spring sag but 31s and 2.5 inch lift look proportianal to me. Maybe my flares are giving me the illusion its sagging? So its not unreasonable to say I could add 1 inch spacers on top of my lift and MAYBE a 1 inch body lift? Would like to have plenty of clearance for 32x11.5x15's.

The bump stop prevents the axle from continuing up during suspension travel. Basically it stops the axle and tires from hitting things their not suppose to.

The bump stop is there to limit the amount of upward travel. Ive seen people remove them for more flex but its really not a good idea, you can get shorter bump stops and that would be fine but that puts you back to watching your brake lines and other parts because of the added flex.

Im no expert but the way i would do it is to flex the jeep with a jack or by driving on something "safe of course" and inspecting to make sure your axle hits the bump stop before it over extends any thing or your tires get in to your jeep. Hope that helps!

OK so you want to go from 31s to 32s. Half will be above the axle and half below, so 1/2" closer to the wheel wells, and you're wanting to add two more inches of lift? Any problem at all with clearance of the 31s? I think you would need a lot more mods to make 2" spacers work with a 2 1/2" lift.

Moreless I want 1 to 1.5 inches more lift without a body lift. Forget about the tires I know I can fit them. I hope I have not confused anyone.I want to accomplish this with a 1 or 1.5 inch spacer on top of my coils. I am hoping that I can just add spacers and no other mods. Thanks for you guys help so far. I m just a stupid newbie to Jeeps.

Adding 1" of spacer most likely would be fine but start pushing 1.5 to 2" and you most likely will have other mods to worry about. Every Jeep is different and there is no way to tell for sure until you do it.
