Sierra HD skid plates (2020–2026)

Engine, transmission and cat shield, and transfer case plates for the 2020–2026 GMC Sierra 2500HD and 3500HD, plus the full package. 1/4-inch 5052-H32 aluminum, powder-coated, bolt-on, lifetime warranty, made in Colorado.

The AT4 package puts protection at the front and leaves the transmission, converters and transfer case open — the run that costs the most to fix. Our Sierra HD and Silverado HD buyer's guide walks through it, and the install instructions cover both brands.

Same plates fit the Chevy Silverado 2500HD/3500HD.
