Fits 2003-2012 Dodge Ram 2500. For stock height. Bought these thinking they would fit a 2007 duramax but I was wrong. I was going to return them but they charge a 20% restocking fee and shipping. I paid over $400 with shipping. Asking $375 obo. I installed the rears and when I moved to do the fronts I realized the mistake. Never used, pulled the rears off and put back in the box. Still in original packaging.
