GMC Sierra EV Tonneau Covers

GMC Sierra EV tonneau cover lineup

The GMC Sierra EV is GMC's full-electric pickup, sharing the platform with the Chevy Silverado EV. It uses a 5'11" bed and the Multi-Flex Midgate that can extend bed length into the cab. Cover availability is growing since the Sierra EV's 2024 launch.

Most-shopped covers for the Sierra EV include the BAKFlip MX4, the Extang Trifecta ALX, and the RetraxPRO XR with T-Slot rails.

Sierra EV shares its bed platform with the Silverado EV — covers fit both interchangeably. The platform uses different bed-rail geometry than ICE Sierra 1500 trucks, so ICE covers are not cross-compatible. The Multi-Flex Midgate limits compatibility for some hard folding covers — verify Midgate-compatible variants before ordering if you plan to use the feature.

Run your Sierra EV through the fitment tool or message us before you order. Fitment is verified before every cover ships.
