Don't.
Go 3-3.5" max. On a 4-5" WJ lift, you're now into Adjustable Control Arms territory. With Grands, there is only one brand of those to get, JKS. For all 8 (upper, lower for both front and rear), you're looking at $1600 + install. The reason you'd want JKS, is they have Rubber bushings. The Polyurethane bushings on Rubicon Express, etc are hell on Unibody vehicles. You will jolt on every decent crack, pothole, etc, not to mention every bolt, pin is jarred that much more, increasing wear and tear. Also with a 4-5" you are in "death wobble" territory.
Also, with 33's, you'd want a minimum of an 8.8" rear, with Single Piece 31 splines up front for the Dana 30. Now you're talking even more money. 33" tires are also too heavy for "stock axles". Go with 31's or at most 32".
If you get a lift, order it from Kevin's and ship it to that shop. I own a Grand Cherokee (95 ZJ) on a 3.5" "Front to rear lift". I have 31" Trexus M/T's on mine

You and I haven't seen eye to eye at times Junky, but I'll help you personally pick out a lift, give you Grand Cherokee advice. If you do it, be safe about it.
