I wish to lower my 2000 4wd dodge durango slt. I have a few questions. I hear that blocks are the best way to lower your truck in the back. But what about the front? Are springs the best? I'm shooting for about a 2 inch front 3 inch rear drop. What would be the best combination of parts to achieve this? Also, I have to be able to tow a trailer occasionally. Does anyone know of a place where you can buy a hitch that either adjusts or is at a higher height than the hitch I recieved in my factory towing package? If anyone can answer any of my questions that would be great.
