Also I think the 6.7 stick dampers work almost as well as the aftermarket dampers because I believe they are a fluid type damper. Not to sure on this but hopefully someone can elaborate a little more as they would know more about it than me.
After doing some research, which I should've searched 1st, The 6.7 will work but the will hit the fan pulley...if you search for 6.7 dampers for the 5.9, there is a thread about it.
