First of all I want to say thanks in advance for any help or answers y'all can help me with. I am picking up my new toy in 2 weeks, 1990 Sammy garage kept since new , 46,000 original miles. Anyway,,, wanting to lift it 3", shackles or new springs and shocks???? I have owned several jeep wranglers and lifted them myself, but never had to deal with leaf springs. So I can do either 3" shackles or new leafs and shocks, I want the ride to stay close to factory or better. It won't see extreme off road either. Thanks again..
