I have an 04 With coil rears that will be used to tow once in awhile, nothing big just some quads 3500# at the most. I'm thinking of lowering it using the belltech 1.3/3 kit. Now with a loaded trailer, I have about an inch of droop or sag in the rear. With the belltech 3" drop in the back, will the droop be the same, more or less and how much, than the stock springs. thkx
