[QUOTE=ILUVMILS] If we were talking about M116/117, M103, or the 603 diesel I'd think otherwise. QUOTE]


The 603 really should not be put in the same catagory as the V8's. On the diesels you change the chains because they stretch and your mileage and performance degrade. However they should last 300k+ miles before I would even think one might break. The newer 606's I would venture to say almost never need the chains done, maybe at 400k.

I have 244k on my original chain but I will do it soon just for the heck of it.
