Pr those of you that know about the lift vibrations i was wondering with a 4.5" lift if you need just an SYE to eliminate vinration problems? Or if you need an SYE and driveshaft?

More than likely. I've heard of very few people that don't need it but definitely plan on spending the money for a new driveshaft and sye combo

If you can afford it go with the SYE. 4.5 would be just a tick over where you would want to run with out one.. TC drop is ok but may still find vibrations. With a SYE you have to add a new shaft. Some kits come with one, and some people just use a front off another Cherokee..

Also lets say i had a 3.5 lift installed and the IRO HnT installed with the 3.5 if i upgraded to a 4.5 would i need a new HnT kit?

u can do a hack and tap instead of a full sye and u can use a front drive shaft from a cherokee to and save alot of money...as of rite now im running a 4.5", TC drop & 6 degree shims and i very little vib but im planning on get a hack and tap and a stock front drive shaft

Go with a full sye it's not that much more $$$ wise. With mine went with jb conversion sye. Love this thing can use a front ds with this kit too. Since I have an ax15 I ended up using a zj front ds since they a few inches longer. Also with hnt you need to make sure drilling dead center
