I figured I would post a reply and help some other readers out when trying to decide what lift to go with.
Mainly due to a tight budget... I decided to go with this lift. I have been happy with it so far since installation 6 months ago. No sagging- I'be pulled light trailers, loaded up the back, and had hardtop on/off with no issues. The spring pack seems to have as much rust on them already as the 22 year stock springs. It's just surface now, and no big deal. Flex is okay, I wish I had more... I didn't reattach the sway bar, and I can't tell a difference. Here are a few photos from this weekend
Lift is super rough/ bumpy.. I can't drink from a coffee cup anymore when driving
But hey, it's a Jeep right!
