Just moved up to a 2007 3500 Automatic 4X4 Dually 6.7L mfgd in June 07, with 47,350 miles on it, from a 2006 5.9L 2500 with 53450 miles (which I loved). Needed the larger truck to pull my 5er. So my question is when I look at accessories/parts they want to know if my truck is a 07 or a 07.5. How can I tell which one it is? Thanks for your help.

 

If I'm not mistaken, if it's got the 6.7l it's a 07.5, 5.9l would be a 07.

 

^^^This would be correct.

 

Its in the "Better Than Ford and Chevy" Class


But yea, its an 07.5
