Hello i have some questions about the difference between gas and diesel parts for the years 2005-2007.What are the differences between gas and diesel axles are there any? I've been led to believe that for 250 and 350 trucks the rear is a sterling 10.5 and the front is a dana 60. Is this true and are there any differences between gas and diesel? I know the older 250 trucks came with a Dana 50 solid. Is that still the case for those years of trucks? Also is there a difference between frame strengths. I have all these questions because I'm looking for a donor truck for a body swap that's getting a dt360 as an engine and trans is an Eaton 6 and my research hasn't been helpful for drive trains thank you.

 

axles and frames are the same for gas and diesel trucks.

 

Front spring rates are different as a diesel engine is heavier
