Very nice solution to an otherwise potential problem!The standoff is set at 1.5" however it will move with my chain adjustment. I took the spacers on the side of the tires and tuned the OD down and slipped over a piece of steel and welded it to the spacers. This steel is what my trailer hitch bolts to with shoulder bolts that way the trailer will float up and down going over hills. It also pivots side to side between the trailer and the hitch for turning. With the hitch being attached to the spacers as I adjust for my chain the trailer will move up and back with it.
