2020-2024 GMC Sierra 2500HD: 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 2020-2024 Sierra 2500HD.

Tonneau Covers

Hard folding, soft folding and roll-up covers, all sized to the exact bed length. Universal versions exist and they are close, but close is where the rattles come from.

Bed Liners and Bed Mats

Spray-in, drop-in and mat options that protect the bed floor without trapping water. This is one of the few accessories that pays for itself on resale.

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.

Ordering is easiest if you have the VIN in front of you. Head to our GMC OEM parts catalog to shop by vehicle, or search for Sierra 2500HD accessories to go straight to a part.
