The Structural Backbone: Extreme Duty Hybrid Framing
While the deck is made of high-strength extruded aluminum—supported by 3″ Aluminum I-beam crossmembers—the foundation relies on massive 4” x 2” tube steel long sills. These steel sills can adjust to fit 34”, 38”, or 42” frames. This hybrid approach ensures you never compromise on the truck's overall structural towing integrity while still reaping the extreme fuel-saving benefits of an aluminum deck. The lower portion features a .125 aluminum corrosion zone, utilizing a low-maintenance aluminum skirt to eliminate the risk of corrosion.
Comprehensive Standard Features
- 6" Fold-Down Sides: Choose between having your sides up or down to easily accommodate your load. Features heavy-duty slam latches and a 6" extruded rubrail to prevent unnecessary road damage.
- Integrated Storage: Supersize your typical truck compartment for more usable storage space. The built-in aluminum toolboxes feature an EPDM closed-cell foam seal to keep tools safe from the elements.
- Adjustable-Height Headache Rack: Modify your aluminum tube headache rack to better fit your specific truck cab. It is durable, practical, features square tube louvers, and comes with integrated LED lights to protect cab passengers.
- Cargo Securing: Secure cargo without added bulk using recessed stainless steel flip-up tie-downs, alongside an extruded 3" tie rail with stake pockets.
- Elite Towing Setup: Pull heavy trailers safely using the 30K Gooseneck Ball Plate with a flush-mount cover (2 5/16” 30k ball included). Safely tow heavy bumper-pull loads via the rear tailboard's 25K receiver hitch with a 2 ½” tube.
- Body & Aerodynamics: Tapered rear with a step provides better clearance for towing and easier access to your bed. 96x102" wide dual-wheel beds feature a tapered front for a more aerodynamic and attractive profile. Includes a premium aluminum fuel door.
