Product Name:Extang Trifecta ALX - 20-24 Silverado/Sierra 2500HD/3500HD - 6'9" Bed (w/out factory side storage) Manufacturer: Extang Manufacturer Part #: 90653 Thoroughbred Diesel Part #: EXT90653 Fitment Notes: 20-24 Silverado/Sierra 2500HD/3500HD
The easiest truck bed cover just got easier. The Trifecta ALX packs the same great features as Extang’s best-selling tri-fold cover, the Trifecta 2.0, but with a Secure Rotary Release Latching System at the tailgate and an automatic latching feature that’ll make getting the goods in and out of your truck bed that much faster.
To unlock, simply rotate the release knob located at the driver side rear and lift, folding the cover towards the cab. This release knob is easy to use and provides unmatched convenience of operation. Another impressive feature of the Trifecta ALX is its auto-latching component. This tri-fold cover automatically secures in place as it makes contact with the bed, allowing you to quickly close and latch this cover without the aggravation of tailgate clamps.
The Trifecta ALX is topped with an all-new, Ancona pebble grained fabric to preserve your truck bed from water, dirt, and dust. Its robust, aircraft-grade aluminum frame contributes to this unrivaled bed protection. The Trifecta ALX is sealed tightly to your truck bed with adhesive-free perimeter sealing to ensure maximum bed and cargo protection. Best of all, installation is a breeze, and it is backed by our Maximum Strength Lifetime Warranty.
