I'm sure I'm not the first person to ask this question, so here it is.......
I've got a 2004 Dodge Ram 1500 RWD 4.7L with a NV3500. I need to do the clutch soon and as I'm shopping for Sachs, Exedy, or Centerforce, I come across an option of 11 inch or 12 inch clutch kits.
Where do I find the information to know which size? Does size matter lol? Please, no Luk lovers lol

 

Of course size matters. How could it be otherwise????

Call the dealer, see what size the stock replacement is, go with that size.
