ok my girl says she is getting me marlin springs for my birthday,so i got a couple questions.if i install the front 4 inch springs on my 85 runner do i have to use the marlin front spring hanger or can i use my stock hangers?will the shackles have to be relocated to mount the front springs.i plan on 4 inch fronts and the 5 inch rears,if i use the front spring hanger this will give me something like 5.5 inches of lift as opposed to the 4 inches the springs alone give, so it seems to me even with five inch rears the truck is going to sit lower in the rear when the springs settle.i plan on running my 35 inch boggers until they wear out then going to 37s.thanks
