Where to get a 7 inch rear coil? Need rear lifted!

[hoe]

As title states I need the rear lifted more with preferable springs. Currently I have pro comp 4" rear coil and 1.5" rear coil spacer. The rear of the truck is still sitting low. Where can I find heavy duty lift springs? My next option would be a 3-4" spacer?

Use z71 springs and call FTS for 6.25" coil spacer. Bolts onto frame and uses stock length springs. Think RCX uses the same method for rear lift. Could get Fabtech 6" (really 5") rear coils and add 1" spacer.
