I am runnings front in the rear,Marlin's 4 in.(need to remove a leaf or two)with Budbuilt hanger,6 center to center shackles thru the frame and on the front downey 3",with 4.5 in. center to center shackles with Marlin's front hanger on the front on my 84..these reason I went this route is because my ranger springs drug on everything and the front axle wrapped like crazy(I didn't have the front hanger on the front at the time) I am very pleased with the setup now and it flexed almost as good as the old setup but feels 10 time more stable
