Does anyone know how the spring perches of a ford ranger 8.8 rear end lines up with the leaf springs of a 91-94 explorer? If not, approximately how pricy is a spring over conversion? Also, what is the best lift to go with for the front end, thats driven 60% on road, 40% off. I'm looking for good manners on road, with a lot of articulation off, extended radiuis arms are a must, and I'd like to stick with 31", but definately no larger than 33" tires. Would 33" fit on the 2.5" suspension lift from rancho and a small body lift? I'd like to know if the extended radius arms are better/worse than the stock arms with lowering brackets. thank you.
