so I know the rears will bolt in after some drilling and the fronts with a RSK, I have a set of springs from an 02 SD but it had the 5.4. Will they support the 7.3.

It all depends what code there were. You had about 6 different spring choices. You need to know what code there are. there is no makings in the springs to tell you what they are, you need to look at the door jam of the truck they cam from
