I bought a '79 one ton 4x4 retired federal truck (more details in sig.). It will be my somewhat tow rig soon enough, but i was looking for lifts and the only company that advertises a 1ton lift is skyjacker. Is the rear spring length longer than a 3/4 ton? I'm wanting 6" with 35's for an aggressive and stout stance, but to still be functional as a tow rig. But one question to add to what combination of lift i get will be is that the cab of the truck sits about a full 1" lower than the bed, chrome trim lines really make it stand out. So with your guys' input, i would like to know what combination would you go with? I'm thinking a 4" DIY shackle flip in the rear and keep the extremely stout/huge spring pack the factory sent out on the truck because i know it can handle a load and not squat much, and do maybe a 4, or 5" front spring, along with a 2" body to level the cab and bed back up. You guys may have a better combination that i can't think of, or reason why my current thoughts aren't going to perform with what i'm asking the truck to still do. Opinions please guys. Thanks.
