# Westin 19-25 Chevy/GMC Silverado/Sierra 1500/2500/3500 Double Cab AT6 Running Boards Black

AT6 Running Boards are designed for full size trucks and feature a 5-inch wide step area with integrated indented pads for solid footing. Built with clean, rounded end caps and bracket covers for an OEM?style appearance, they offer a refined yet rugged look. Two finish options are available, textured black powder-coated extruded aluminum, backed by a 3?year limited warranty, or bright finish polished stainless steel with a limited lifetime warranty. These boards are lightweight but structurally durable, designed to minimize added weight with the strength for the toughest jobs. The footboard and pads are ergonomically placed for comfort and maximum traction. Bracket covers are used to conceal mounting hardware and help preserve that clean factory look. The AT6 models are vehicle-specific fit and include hardware to bolt on the boards with no drilling required. Installation takes about 1.5hrs, and depending on the height of the truck, should not require a lift. The aluminum construction offers excellent weather resistance with proper care and maintenance, but for harsh road conditions or regions where salt is used on the roadways during winter, choose stainless steel. Replace your factory running boards with AT6. They are a sleek, solidly built option with stylish design, ample stepping area, and finish choices for a custom look.
