Greetings Everyone!

I am new to diesels and so I decided to join this forum in hopes of finding an answer to my most pressing question: Is my Dodge 2500 HO an 2004 model or the 2004.5? I am sure the answer is already on here somewhere, but I haven't had any luck in my searches. Can someone direct me to a thread or tell me what keywords I should be searching on? Any help would be appreciated. I am wanting to buy an Edge Juice in the next couple of weeks and I don't know which model I need.

Thanks!

 

I believe that the 2004's are rated at 305 hp and 2004.5's are 325 hp. You can find this info on the plate on the left front corner of the engine.
