Does your Super Duty need a little boost? Then this budget boost was designed just for you. This isn't some loose top spacer that can move around. This lower mount is bolted solid. The spacer is a solid casting that is CNC machined to fit every time. The 2 inch spacer is perfect for the person that adds an aftermarket bumper, plow mount, etc...and just needs that extra 2 inch to make the truck set the way it did from the factory. This budget boost is also perfect to help clear those larger tires that you thought would fit. Finally your truck will sit level!
