What's the problem ?

[Already Gone]

A front suspension rebuild on my truck was just completed. Everything was replaced and the original control arms were used with the stock original front springs and a McGaughy 2 1/2 inch dropped spindle was installed. I am okay with the front height with the dropped spindle installed. A set of McGaughy 4 inch drop rear coil springs with shock relocators were installed as well. So in esssence I did a 2 1/2 - 4 inch drop which should have leveled out the truck which is the stance I want. As you can see in the picture, truck on hoist, the rear seem to be sagging too low. Now my truck didn't lead a hard life and now I look at the pics sat pretty level before the suspension changes. The truck came from the factory with the G50 Heavy Duty Spring option and the original springs are still in great condition. Any ideas or suggestions are appreciated. Thinkin' maybe shouldn't have taken it down so far ??
