Hi, I have a 1994 Ford Explorer. I like to do off roading and would like to put a lift on my truck. I am a high schooler so I don't have a really high budget. I only want to lift it maybe 2 to 3 inches because I don't want to make it unbalanced, just enough to clear a few more objects. I just recently had a re-manufactured engine in it so I have no intention of getting a new vehicle. What would be the different options to lift it and how much do you think they would cost? Also, any advice on how to stop or get rid of rust would be nice also (especially on the bottom of the truck).
