No but 3/4” didn’t amount to much angle change front to back. If I used any thicker spacers than I did I’d probably measure the driveshaft angle and lower the front of the diff down the same to neutralize the pinion angle.
I don’t recommend going too thick on the spacers either, I really feel like the 3/4” ones I have are on the edge of tolerance, not just for pinion angle but suspension geometry.
