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 1 inch spacer is perfect for the person that adds an aftermarket bumper, plow mount, etc...and just needs that extra 1 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.
