What is the best lift kit for 1973-87 chevy suburban?

[Hazieview]

Hey guys I guess the search feature is broken because I can not get it to work.

I was wondering what suspension lift had the best ride quality?

I thinking of just buying a stock suburban and putting a lift on it myself.

What kit should I buy? I want the best ride quailty I can get at a reasonable price. I also want it to be safe and reliable.

I think a 6" lift would be good enough because it will be on the highway quite a bit.

If you could help me out I would appreciate it. Thanks guys!

(no body lifts please. all suspensions. Thanks)
