Best '15 JK lift?

[R Q]

One of my customer's son has a "15 JKU with worn out stock suspension and it needs a lift. He has 285 70 17 tires on it and that's what will stay on it, believe it or not he probably won't wheel it. This Jeep was behind a motor home most of it's life so I guess that's why the suspension is sagging. I don't know much about newer Jeeps so what would be their best bet for a 2.5" or 4" system and yes they'll have it installed. They've been to 4WP in Charlotte. and are unsure of what to do. I have another shop to send them too but I want some recommendations before I go any further.
I see some cheap RC kits but they are pretty minimal and I don't want issues down the road or immediately after installation! lol

Personally on JK i would stay around a 2.5 in lift with 33s, should clear 35s easily. Going to need lower controls arms and id do tracbar atleast in the front.

Something like this https://rockkrawler.com/jku-2-5-adventure-system/ or teraflex equivalent. others will chime in but jk don't need a ton of lift.

2.5" on a Jk you can get away without the lower control arms but it's better to do them. The Teraflex lift is decent just get different shocks. I run Bilsteins but those might be stiffer than they want. I would also do the track bar.

I ran that way for several years, 33's and 35's were fine.
