Hey people,i got a question for all my techy bronc brothers.What is the amount of lift from the factory on an 1989 bronco xlt 4x4? I have 4 shocks up front w/springs and two shocks in the rear with leaf springs. I also have 31 inch tires on 15 inch rims.I would also like to ask the age old question,how much bigger can i go on the tire size with this factory lift? Right now my truck sits about 20 inches off the ground. I bow to your infinite bronconian wisdom.
