Factory Accessories for the Chevrolet Silverado 3500HD: 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 3500HD.

Bed Liners and Bed Mats

Spray-in, drop-in and mat options that protect the bed floor without trapping water. Universal versions exist and they are close, but close is where the rattles come from.

Assist Steps

Factory running boards, available in rectangular, oval, molded and power-retracting versions depending on trim. The fit is the whole argument here.

Bed Rails and Tie Downs

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.
