My wife has a back injury and will no longer be able to climb up to get in. Need to go from a 8 inch lift with 37's to a 4 inch with 35's. My truck has 8 inch over front springs and 6 inch blocks added to the rear. I'm sure the pitman arm will need to be changed as well as shocks. So do I need to replace the entire lift or just the blocks and springs. Was wondering about the rear sway bar and front end connects. Little help? Anyone want to swap?
