Rough Country DEF Tank Skid Plate | 10003 | 2011-2016 GM 2500/3500 HD

Please Call for Availability


Give your diesel truck the protection it deserves with Rough Country’s DEF Tank Skid Plate. On newer model GM trucks the DEF tank extends below the frame of the truck making it highly vulnerable to damage from rocks and debris. Keep this crucial area covered and protected with this handy upgrade from Rough Country. This durable steel skid plate is made of laser-cut CNC bent 3/16in steel plating to provide plenty of extra protection for the plastic factory tank. Unlike many DEF skid plates, each Rough Country kit is engineered with a series of openings allowing water and debris to drain out naturally. For a long lifespan of good looks, each skid is powder coated black with a corrosion-resistant paint.
