since the shock mounting location doesn’t change max droop doesn’t change…of course that assumes stock shock travel/length which is not true with the different aftermarket coilovers with icon and king pushing the droop limits…and fox being pretty conservative…
it is all about max droop…while at ride height the angles increase the same amount but a spacer will lower the shock/coilover allowing the axle to droop more than stock and put the cv angle out of spec…generally a 2” spacer lift is the limit on a bronco
