I had my mechanic install one of these 1" spring spacers from MAF to fix the left front lean after putting in a TJM 2.5" lift and he said it wouldn't fit all the way over the cone shaped bumper in the center. So he shaved out quite a bit of material from the inside of the spacer to make it fit. When I contacted MAF about this they said they've never heard of this happening before, though it is a tight fit. The mechanic said there was no way it was going all the way on without modification. While I have no reason to doubt MAF in this situation I'm wondering what experiences Mudders have had with this part and how exactly you installed it..?
