So i pulled one of my leaf springs out to compare to the worn new used 3invh springs i got. First thing i noticed was that the center pin was further forward then my 5inch spring. Then measured and saw that they were about 1inch lower. So i pulled one apart gave it new pads, bushings and coated with grease before putting it under. The 2nd one i just threw under. Keep in mind i have been running my 5inch springs with the 1st and 3rd leaf removed. The 3inch spring the shackle unfortunately
