Heavy-Duty Protection with a Distinctive GMC Look

Upgrade your GMC Sierra 3500 HD dually with the Truck Hardware Gatorback Black "GMC" Logo Dually Mud Flaps - Set. These premium mud flaps provide superior coverage for your truck's rear wheels, protecting against mud, gravel, and road debris, all while showcasing the officially licensed GMC logo with bold black lettering on a 304 stainless steel plate. Built to withstand harsh road conditions, these mud flaps ensure your vehicle remains protected and stylish.

Premium Construction for Lasting Durability

The Gatorback Black "GMC" Logo Dually Mud Flaps are constructed from 21" wide and 1/2" thick heavy-duty rubber to ensure effective debris blocking and durability. The stainless steel plate features the officially licensed GMC logo in black letters, adding a custom, rugged look to your vehicle. Custom-fit rear support brackets are made from a durable nylon and fiberglass composite that will not fade or chip over time, ensuring your mud flaps not only perform well but also maintain their great appearance.

Effortless No-Drill Installation

Installing these mud flaps is simple and straightforward, requiring no body drilling. The mud flaps use factory mounting points, and custom-fit brackets and hardware are included for a secure fit over OEM splash guards. The rubber portion of the flap is removable from the bracket via a built-in channel, allowing you to slide the flap in and out for easy removal, which provides options for additional ground clearance when needed. Everything you need for installation is included, and you can get it done with tools you have at home.
