2020-2023 Chevrolet Silverado 3500HD: 6 GM Accessories That Earn Their Money

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 2020-2023 Silverado 3500HD.

Bed Liners and Bed Mats

Spray-in, drop-in and mat options that protect the bed floor without trapping water. The fit is the whole argument here.

Trailering Hitch and Wiring

Factory receiver, ball mounts, 7-way harnesses and trailer brake controller components. The fit is the whole argument here.

Wheel Locks

Keyed lock sets in finishes that match the factory lug. Universal versions exist and they are close, but close is where the rattles come from.

Bed Rails and Tie Downs

Cargo management hardware that uses the existing bed stake pockets. Order it in the finish that matches your trim and it looks factory because it is.

All-Weather Floor Liners

Deep-channel rubber liners molded to the exact floor pan, with the factory retention posts still doing their job. This is one of the few accessories that pays for itself on resale.

Sport Bars and Bed Steps

Styling and access hardware that mounts to factory points. Universal versions exist and they are close, but close is where the rattles come from.

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.

We are a factory GM dealer, not a reseller, so what you order is the same part the service drive installs. Browse our Chevrolet OEM parts catalog or search for Silverado 3500HD accessories.
