I hve 1991 Ford Explorer Sport 2Dr. 4x4. I want to lower it but I can only find front lowering springs. I need the rear to be lowered too. If anybody can give me links to websites that carry full lowering kits for that year I would greatly apreciate it. I DON'T WANT AN AIR RIDE SUSPESION, TOO COSTLY FOR ME! Can you also tell me the parts that I would need to lower it? Thanks!
