GMC Sierra 1500 Running Boards - Westin - AT6 - Black - 2019-2025. These 5-inch boards provide solid footing and an OE-style look for your Sierra 1500.

Built from extruded aluminum with a textured black powder coat, AT6 offers strength without excess weight. A full-length 5-inch step with integrated indented pads delivers traction in wet or muddy conditions. Rounded end caps and bracket covers keep the profile tidy while concealing hardware. Vehicle-specific brackets and included hardware allow bolt-on, no-drill installation; typical time is about 1.5 hours. For regions with heavy winter salt, consider the polished stainless version (sold separately). Black aluminum carries a 3-year limited warranty; stainless offers a limited lifetime warranty.
