Factory Accessories for the GMC Terrain: 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 2018-2023 Terrain.

Wheel Locks

Matched-finish lock sets. The fit is the whole argument here.

Trailering Hitch and Wiring

Receiver and harness packages for SUVs that were not ordered with a tow package. Universal versions exist and they are close, but close is where the rattles come from.

Roof-Mounted Cargo Carriers

Hard-shell and basket carriers rated for the factory rail load. The fit is the whole argument here.

Roof Rack Cross Rails

Factory-engineered rails and the accessory carriers that attach to them. This is one of the few accessories that pays for itself on resale.

Illuminated Door Sill Plates

Brushed and illuminated sills with model script. This is one of the few accessories that pays for itself on resale.

Assist Steps

Molded or power-retracting steps for the full-size SUVs. 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.

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 Terrain accessories to go straight to a part.
