Factory Accessories for the Cadillac CT4: 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 2020-2023 CT4.

Wheel Locks

Matched-finish lock sets. Universal versions exist and they are close, but close is where the rattles come from.

Ground Effects and Spoilers

Primered or color-matched aero kits. Order it in the finish that matches your trim and it looks factory because it is.

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 Cadillac OEM parts catalog or search for CT4 accessories.
