Factory Accessories for the Chevrolet Silverado 2500HD: A Practical List

Factory accessories get dismissed as the expensive option, and sometimes they are. But GM Accessories are engineered against the actual vehicle, they use the existing mounting points, and they do not void anything. Here is what is worth it on a 2015-2019 Silverado 2500HD.

Splash Guards

Molded front and rear guards that match the flare contour. The fit is the whole argument here.

A Note on Fitment

Accessories are more trim-sensitive than mechanical parts, not less. Bed length, wheelbase, roof content, ride height package and interior color code all change the number. Send us the VIN and we will confirm before anything ships.
