i have a two inch body lift on my 87', i think the only thing that was tight was the hydraulic line for my clutch. a three inch body lift would probably make others things a stretch. with my two inch BL i cleared 33's. we had some at work and it was slow so i threw on the front and rear and no issues. it even tucked up in the rear fenderwell nicely. the only thing the tire came in contact with was my front mud flaps when i turned the wheel. but you dont need those.
