These brackets are a Ford authorized accessory. That gives you piece of mind that using this will not effect the warranty on the truck. These brackets are designed to be 100% no body drill so the paint and the aluminum body of the truck will stay intact. These brackets work with the cut style 12" wide mud flaps. They are a 100% aluminum construction and include all the hardware and fasteners needed to install your new Ford Super Duty mud flaps. If you have the Lariat protection package with the liners there are two small cuts that need to be made to relieve the pressure on the bracket pressing against the inner liner.
