      Unique 3-Panel Folding Hard Cover. No other tri-panel folding hard tonneau cover offers the unique access to front and rear panels that's provided by the EnCore from Extang. The EnCore is an innovative composite alternative to aluminum panels that features a truly slick locking system as well as quick, easy cover removal and installation. Your Sierra 2500 bed will be a secure and low-profile stunner when it’s wearing this amazing tonneau cover system.

      Superior Design and Construction. The Extang EnCore starts with high-quality aluminum rails manufactured to precise dimensions and finished in a durable black powder coat. The cover is made up of EnCore composite panels, which feature a high-strength automotive-grade polypropylene core. It's then wrapped in an EnduraShield skin that is specially formulated to resist scratches and dents, as well as the harsh fading action of the sun. The system is secured by BOLT® single-key locking technology, utilizing your Sierra's ignition key to instantly lock the entire cover in place.

      Quick and Easy Installation. In most cases, the EnCore Hard Tri-Fold Tonneau Cover can be installed without any drilling required. Once the rails are in place, the 3-panel cover simply self-latches. You can also remove the cover almost instantly if need be and then, simply set back in place when you need it again.

      Three-Year Warranty. Extang provides a 3-year limited warranty on the EnCore cover system.

      Application. The Extang EnCore Hard Tri-Fold Tonneau Cover is specifically designed to fit 2020-2022 Sierra 2500 HD models without Factory Side Storage.
