Dee Zee DZ1800 Full Size Brite-Tread Mud Flaps

Flat universal aluminum flaps in Dee Zee's Brite-Tread diamond-plate finish, 12"×16" per pair, rear-axle only. Installation requires drilling into the wheel well; nuts and bolts are supplied, though owners recommend self-tapping screws for better long-term retention. Community fitment on a GMC Sierra confirms the width covers the tire with room to spare. Durability evidence is mixed: aluminum does not crack or UV-fade but can bow over time; community reports describe a roughly three-year lifespan before permanent bending began, while others describe the material as thick as a toolbox panel. The set is intended to complement Dee Zee's Brite-Tread running boards and accessories. Does not fit vehicles with fender flares or lip molding.

Right pick for full-size truck owners who already run Brite-Tread accessories and want a matching diamond-plate aluminum rear flap at a competitive price, particularly if the vehicle has no fender flares. Skip this if your truck has fender flares or lip molding (confirmed incompatibility), if you need front coverage (this is a rear-only 2-piece set), or if you want a vehicle-specific no-drill fit with multi-year community durability evidence behind it. The Husky Liners MudDog is a comparable universal drill-in option with more community durability data.

No chemical exposure pathway · Brite-Tread aluminum passive exterior accessory with no SDS. Aluminum construction generates no microplastic particles through road abrasion, unlike thermoplastic or rubber alternatives; end-of-life, single-material aluminum is accepted by standard curbside municipal recycling in most US regions. No manufacturer take-back program exists for this category.
