SPC UCAs from RockAuto

I thought similarly.. i see UCAs as insurance even if lifting less than 2". Theory being an aftermarket arm is stronger than the stamped steel stock arm..

here is my concern however. A taller than stock tire size requires more caster to physically push the wheel toward the front bumper because otherwise it would be hitting the body mounts. The upper control arms that add caster don’t push the wheel toward the front so the stock adjusters aren’t really moving them. I don’t know how this affects fitting larger Tires bit my speculation would be that tires wouldn’t fit as easily.
