What size did you go with. I bought the 3/4 inch, but I see alot of posts with the 1.5"The spacer will level it out. As much as I like the looks of the level stance I went without the spacer and the rear is ever so slightly higher with the steel bumper and the winch up front on my 80th Anniversary. Ask the dealer if they will install and if there would be any impact on warranty. I doubt a dealership would want to take responsibility for an aftermarket product with unknown qualities. Also, if the aftermarket product is in the path or vicinity of any failure, it would be called into question for any warranty repairs. Here is a picture with just the Mopar lift.
Mine has the Mopar lift only. NO SPACERS. I use the black trim around the fenders, at center of wheel, as the spot I measure up to when comparing front to back vehicle height. Today about a year after steel bumper and winch install the front is at 42.25 inches and the back is at 42.75 inches. Considering this I would not use the spacer with the Mopar lift.
I put Daystar 3/4" spacers all around on mine - and it went in for multiple things over the 30 months I had it. No one ever questioned a thing. 3/4" is nothing.
