Question Please! Need info/ advice !

Uggghh.. if you've read my previous posts you probably think that Im clueless

I have a 2 inch BB on top of upgraded 18/59 coils (up from 14/55). Im thinking this got me approximately 3-3.25 inches of lift. With this and chopped stock fenders I am running 35s.

Soooo my question is, do I need to upgrade change things such as the trackbar/ bracket, swaybar links?

Im wondering this because even though my total lift gain is somewhere around 3,"
about 1-1.5" of this is from stock springs off of another jeep. Should my hardwear be the same as the 4 door with a hardtop and towing package that I got the springs off of? If so then Im thinking I dont need to worry about changing anything else yet since I only lifted the jeep 2" over "stock" ?????

If this makes any sense and you have any input/ advice I'd appreciate it!!

What bb did you get did it come with new rear sway bar links if not you can just invest in some quick discos for the front and leave it at that Idk if this helps any sorry my reason for asking about the rear was if it came with new rear links you can use the current ones on the rear up front

I'm not sure if I'm understanding you correctly, but the front end suspension components should essentially be the same between your jeep and any other, aside from the fact that the coils might differ between jeeps with different stock curb weights and the shocks will differ based on whether it's a Rubi or not (as well as the presence of an e-disco). So there really aren't any major suspension components you can switch out between another jeep and yours and accomplish anything. The springs you swapped into your jeep are stiffer, and might have given you lift, but only because your jeep is lighter than the one the coils came off of. In other words, the ride height of the stock donor jeep was probably about the same as your stock jeep, aside from any height difference due to different tire sizes, therefore the suspension geometry between both stock vehicles would essentially be the same or very similar.

The BB did not come with new sway bar links. Im going to get quick discos soon but while doing some research on here I read a few times that with with anything over a BB I would need extened sway bar links and trackbar brackets or adjustable trackbars. Since I got more than 2 inches with the stiffer coils i was wondering if it was necessary.

You will be fine your axle will not be off by much and driving you won't notice it at all and your rear links are fine and your fronts will be ok till u get your quick discos

I run a 2.5 bb and I spent the extra money for the rear track bar relocation bracket a buddy of mine has the same lift without the bracket and his drives normal as well. I also don't have a rear sway bar I took it off completly

If it isn't too flighty for you, don't worry about the caster.

If having the axles off-center doesn't cause any driveability issues or bug you visually, don't worry about trackbars/brackets.

You do, however, want to keep your swaybars level. When flexed, short links can cause the swaybar to flip around backwards, snapping or pretzeling the links and possibly causing more damage. This has been known to happen on a lift at the shop. Longer links are fairly cheap, so it's something to keep in mind.

With appx 3", you should also flex it out and check your brake lines.
