Another thing to remember is that when you get a smaller or shorter side wall on the tire the ride of the truck will get rougher and change.
There are a lot of sites that list 99-04 and 05-07. A few local tire guys also said that it's the 05 and up rims that need spacers. I'm not sure I'm comfortable with the idea of spacers on my truck.. it's heavy and the last thing it needs is more stress on the wheel studs.
Unless these spacers are different than the ones I saw idiots running in years past, all I see is broken studs.
