Just my opinion, if you go 1.75” in the front, I think you’ll want to go .75” or 1”in the rear.
I have 1.75 lift in the front with .5 in the rear. With no weight, it sits perfectly level with maybe a .5 rake measured at the top of wheel wells. Any amount of load in the back drops it to a reverse rake. I originally had 1” spacers in the rear and thought it was too much forward rake (1.5-1.25 depending on side/fuel) so I switched to .5 spacers. Really wish I had gone .75. When I hook up to my empty utility trailer, I get reverse rake.
