whiplash sagging springs

[Chubacabra]

Well one of my whiplash springs have settled one inch and a quarter. People said one here that they've been known for doing so. So what can I replace it with? I was thinking of full throttle springs. Or sky jacker spring possible stacking a spacer on top. But since guys in here use the 7 inch diesel springs from skyjacker,I thought about using the 10 inch 3/4ton ones from full throttle. This way maybe I can get 13 inches of lift,since my rear is sitting 1 1/2 taller. ANY input?

What size springs is it??? i would replace it with either skyjacker or some diesel coils. the diesel coils will definitely ride rougher but im sure you knew that.

go skyjacker if possible. You cant beat there lifetime replacement warranty. I haven't heard anything bad about full throttle coils tho and was thinking about going that route to do away with my spacers on the front
