Hey all I have a very nice set of Cal-Tracs from my recently sold 08 F250 4wd. These will obviously fit 2008-2010 but I am not sure about other years. They will more than likely fit 6.0's and 6.7's as well. I bought new leaf spring bushings and heim joint ends from Calvert which are included. Also included are the correct ID urethane tube insulators for the front brackets to eliminate "clanking" on the street. These are $469 + ship (easily $30 for the weight of this setup) from Calvert, I am asking $350 shipped.
