I got a 2009 Pro-4X. I've read some threads about the same clunk I believe I am getting. My truck has a 3in body lift. I'm going to replace the stock rancho suspension and hopefully solve the problem. Anyone have any recomendations for suspension? Do I go with Radflo or Bilstein 5100's? or maybe the Radflo's in front and Bilsteins in the rear? I do lots of highway driving but I do go hunting/tow a boat ect..
