I have a 3" skyjacker lift on my 97 ram 4X4 plus 1" custom blocks in rear. I'm not sure of the exact lift kit, but it did come with rear leafs that replaced the 3" stock blocks and new coils in front. I was wondering if I could replace the 3" lift coils with 5" lift coils? Do I have to change other things as well. I know I will have to change brake lines and shocks and I do have the track bar adjuster and plan on the drop pitman arm. What else am I getting into? For the rear I want to remove the 1" block and put the 3" stock blocks back in. Any help on this?
