Quality differences are negligable, in my opinion, but you can buy a 'heavy duty' drop spring. Ride would be harsh, but you could still haul almost like you did with stock springs.

I know others will follow me: ECE is awesome! No hassles, no incorrect parts, no bs, good customer service. Great adjustable track bar setup, too. CPP does have a relative cheap rear lowering kit that has springs, shocks, shock relocator brackets, custom panhard bar and brackets. Pretty good deal, but the customer service is not as good as ECE.
