One of my friends has this 4.5 Hellcreek you speak of, it is rough country stuff. Heck some of the hardware packets still said rough country and had some rough country decals in the box. Be prepared for it to be a bit bigger than 4.5", his sits at roughly 5.5" and it has been over a year since we put it on. The only problem with the lift is the shocks that it comes with are crap. They wear out after a few months, then they start squeaking like your jeep is full of starving puppies. Other than the shocks its a pretty sound kit, it went on smoothly and hasnt had any problems with sagging (still flexes nicely too). I would say go ahead and buy it but buy some brakelines and shocks at the same time (you could always try to sell them to some other poor soul on ebay). Good luck with it all.
