DNA Motoring Cargo Box
Our DNA Motoring cargo box delivers the extra storage you need without compromising your vehicle’s aerodynamics or fuel efficiency. Built for road trips, ski weekends, and everyday hauling, this rooftop cargo carrier combines heavy-duty ABS construction with a sleek, low-profile design that slices through wind resistance.
Whether you’re packing camping gear, sports equipment, or luggage for the whole family, the spacious interior and dual-side opening system make loading and unloading effortless from either side of your vehicle. We engineered this box to handle everything from summer heat to winter freeze while keeping your cargo bone-dry mile after mile.
What makes this cargo box stand out
Construction & Weather Protection
The DNA Motoring cargo box shell is molded from impact-resistant ABS plastic, the same material used in protective helmets and automotive body panels. This thermoplastic resists cracking in sub-zero temperatures and won’t warp or fade under intense summer sun, maintaining structural integrity season after season.
Our continuous rubber gasket runs the full perimeter of the lid, creating a compression seal that blocks rain, snow, and road spray from reaching your cargo. We tested this seal in simulated downpours and high-pressure wash conditions to ensure complete waterproof protection.
Universal Roof Rack Compatibility
We designed the DNA Motoring cargo box mounting system to fit nearly every factory and aftermarket roof rack on the market. The adjustable U-bolt clamps accommodate square, round, and oval crossbar profiles from 1.5 to 3.5 inches wide, covering popular systems from Thule, Yakima, Rhino-Rack, and OEM manufacturers.
Each mounting clamp features a rubberized contact pad that grips your crossbars without scratching powder coat or anodized finishes. The tool-free knob design lets you hand-tighten the hardware securely in minutes, with no wrenches or special tools required.
Interior Capacity & Loading Access
Inside, you’ll find 16 cubic feet of cargo space—enough room for four full-size suitcases, six pairs of skis, two snowboards with boots, or a weekend’s worth of camping gear for a family of four. The smooth interior walls maximize usable volume and make cleaning simple after muddy or dusty trips.
The dual-side opening system is where this cargo box truly shines for everyday use. Both driver and passenger sides feature full-length hinges, so you can open the box from whichever side offers easier access in tight parking spots or crowded campgrounds. Internal support struts hold the lid open hands-free while you arrange gear or dig for buried items.

Common Questions About the DNA Motoring Cargo Box
The universal mounting system fits most factory and aftermarket roof racks with crossbars between 1.5 and 3.5 inches wide. The adjustable U-bolt clamps accommodate square, round, and oval crossbar profiles from popular manufacturers including Thule, Yakima, Rhino-Rack, and OEM systems.
Before purchasing, measure your crossbar width and profile shape. If your vehicle has bare side rails without crossbars, you’ll need to add crossbars first—our DNA Motoring roof rack cross bars are designed to work seamlessly with this cargo box.
The DNA Motoring cargo box weighs approximately 38 pounds empty, making it manageable for one person to lift onto the roof during installation. Once mounted, the aerodynamic profile minimizes drag and wind resistance.
Most customers report a fuel economy reduction of 1 to 2 mpg at highway speeds with the box empty, and 2 to 3 mpg when fully loaded. Driving at moderate speeds and avoiding rapid acceleration helps minimize the efficiency impact of any rooftop cargo.
Yes, the waterproof gasket seal is designed to keep contents dry in automatic car washes, rain, and snow. We recommend using touchless car washes when possible to avoid potential contact from rotating brushes, though the ABS shell is durable enough to handle brush contact.
Always ensure the lid is properly closed and locked before entering a car wash. Check that all mounting clamps are tight to prevent any movement during the wash cycle.
The cargo box is rated for a maximum load of 110 pounds distributed evenly across the base. This capacity handles typical camping gear, luggage, sports equipment, and travel supplies with a comfortable safety margin.
Always check your vehicle manufacturer’s roof weight limit before loading, as your vehicle’s capacity may be less than the box’s rating. Most sedans and SUVs support 150 to 165 pounds total on the roof, including the weight of the rack, box, and cargo combined.
The DNA Motoring cargo box features a dual-lock system with a single key operating both mechanisms. One lock secures the cargo box to your roof rack crossbars, preventing theft of the entire unit. The second lock keeps the lid closed during transit and when parked.
Both locks use the same key for convenience, and two keys are included with your purchase. The lock cylinders are weather-resistant but benefit from occasional lubrication with silicone spray to maintain smooth operation.
Yes, the dual-side opening system allows you to access the interior from either the driver or passenger side. Both sides feature full-length hinges and internal support struts that hold the lid open hands-free while you load or retrieve gear.
This design is especially convenient in tight parking spaces, narrow garages, or when one side of your vehicle is blocked by another car. You’re never forced to access the box from a difficult angle.
Most customers complete the initial installation in 20 to 30 minutes working alone, with no specialized tools required beyond what’s included in the package. The process involves positioning the cargo box on your crossbars, sliding the U-bolt clamps into the mounting channels, and hand-tightening the securing knobs.
Once you’re familiar with the system, removal and reinstallation for seasonal storage takes about 10 minutes. The tool-free design eliminates the need for wrenches or ratchets.
