      Description

      Progressive Cargo Protection. Protect your Sierra truck with the Retrax RetraxONE MX Tonneau Cover. This tonneau cover features a progressively-designed, 1-piece reinforced shell that’s engineered to provide maximum all-weather protection compared to retractable covers using a segmented shell. Additionally, this truck bed cover is designed to mount almost fully flushed against your bed rails for an aerodynamic look that also helps reduce wind drag.

      Versatile Retractable Style. The RetraxONE MX Tonneau Cover is a retractable roll-up cover that retracts into a compact canister. This canister features specialized spiral rails built-in that keeps the cover from coming into contact with itself when rolling up, greatly reducing wear and tear. This cover also features a sealed ball-bearing roller system for smooth operation and automotive-grade weather strips that seal the cover tightly, preventing leaks. Moreover, this tonneau cover uses a unique latching mechanism that can be locked at any point of its railing providing you with nearly unlimited truck bed loading options. Lastly, this latching mechanism keeps the truck bed cover fully secured with the tailgate raised and locked.

      Tough Build Quality. The Retrax RetraxONE MX Tonneau Cover is constructed from a tough, 1-piece, high-grade polycarbonate that’s highly resistant to moisture, UV rays, and extreme temperatures. High-grade aluminum reinforcing ribs provide the cover with exceptional rigidity. Likewise, strong aluminum mounting frames provide long-lasting durability and corrosion resistance. Finally, this tonneau cover features a rugged matte black powder-coat finish for superior corrosion protection and classy looks.

      Trouble-Free Install Procedure. Installing the Retrax RetraxONE MX Tonneau Cover is a trouble-free procedure as this component mounts on your truck bed using included mounting rails and no-drill clamps. The included drain hoses use preexisting holes on your truck for their exits. You may choose to drill a couple of holes through the plastic plugs that cover these holes for a cleaner look, but this step is optional.

      Includes a Limited Lifetime Warranty. The Retrax RetraxONE MX Tonneau Cover includes a limited lifetime warranty covering manufacturing defects. Please visit the manufacturer’s website for more details.

      Application. The Retrax RetraxONE MX Tonneau Cover fits all 2020-2024 Sierra 3500 HD models with Standard Box and without Factory Side Storage.

            Easy to find what i was looking for. Lots of great photos, and even able to match the year, make, model, and color of my truck for great reference to what the product will look like installed on my truck.
