A couple of months ago I had 6112's (set @2.5) put on the front and 5160's on the back. I took the hardware to a shop who installed it and told me theoretically that the truck should sit level when they get done. I asked about needing shackles in the back and they told me that I would not. Now the truck looks higher in the front then the rear and I was wondering if it is true that I need shackles and if so what size?
Thanks
