GMC Sierra 2500 Running Boards – Westin AT6 – Black – 2019-2025. Purpose-built for your Sierra 2500, these boards provide a broad 5-inch step and an OEM-style look with confident footing.

AT6 boards use textured black, powder-coated extruded aluminum for strength without excess weight. Smooth rounded end caps and bracket covers keep a clean profile, while ergonomically placed, indented pads enhance traction. Vehicle-specific brackets with included hardware allow a no-drill, bolt-on install in about 1.5 hours; a lift is often unnecessary. For frequent winter road salt, the AT6 line also offers a polished stainless option; this listing is the black finish.
