Yep you sure can. Are you doing the whole kit? Springs, Locks, and so on?

Yep, they will bolt right on. They're a little stronger than than the stock C5, but are proably only good to around 550 lift

Do you know what year the springs are? You might want to post some pictures of them. If they are early LS6 springs I would pass and purchase later models. Just my opinion.

2003 should be good springs as long as you're running the stock cam.'
You can use your stock retainers and keepers; they're not a wear item
