1987 Suburban Help

[Tas0718]

I have a 87 4x4 burban with 12" of lift and I want to drop it down to 6"-8" inches of lift and run 37" tire. The lift I have now is a Super Lift and it is crap. It has drop about 4" over the last couple of years. What is the best lift this heavy trucks and what price am I looking at. I know ill have to have a complete system. I have searched this site and many other but I haven't found anyone that is going from a higher lift to a lower lift. I will also be doing a 1/2 ton to 3/4 to swap but I've got that cover. This truck is used mainly for hunting and pulling.
