5.5 IRO Lift

hey guys i know this has probaly been asked before but hell ill ask again. i plan on upgrading my 3.5 llift with IRO 5.5 longarm kit soon. I have the 249 tc but was curious if i should swap it out or if it needs be i rather not i dont mind the 4wd all time. also if i should worry about driveshaft angles, increasing the length or a sye? Overall im just looking for what i might run into for problems along the way lifting my zj this high and may be able to avoid beforehand. thanks!

Opt for at least adjustable uppers in the rear. That'll let you dial in your pinion. IRO long arms have a pretty good amount of caster adjustment built in to the y-link. I don't think you'll have a problem with the front angle. The 249 should be fine with that lift. Also, ZJs generally don't require SYEs; Some are exceptions, however.

You'll need to address the front shaft, easiest and best method is to switch it to a u-joint style shaft.

I forgot about that. My ZJ had a u-joint shaft for some odd reason. The PO was an old lady so I know she didn't swap it...
