What an amazing difference!!! I cut exactly two coils off the top of the spring and it dropped the truck exactly 4 inches. I also removed the bump stops. When I drove the truck it was super smooth, better than stock. I positioned the cut section of coil under the frame. It looks and feels safe while driving. The front of the truck has 1.5 coils cut also. Got tons of looks and thumbs up!! Tires sizes are 225/60/15 and 31x10.5x15
