Roof Rack Storage Boxes & Cargo Cases

Low-profile hard cases engineered to mount cleanly on roof racks, crossbars, and platform racks — IP67 waterproof, TSA-approved, and slim enough to clear your garage door.

Shop Low-Profile Cases

Eylar® roof rack storage cases solve the two problems every rooftop box fights: wind and weather. The low-profile cargo case line runs just 6.12" to 6.3" tall on the 38"–48" models, so it minimizes wind drag at highway speeds and clears low garage doors and parking structures that taller boxes can't. Inside, a reinforced polypropylene shell with a rubber gasket lining delivers IP67 waterproof and dustproof protection — your gear stays dry through driving rain, river-crossing spray, and a full season of dust.

Why Low Profile Matters on a Roof Rack

  • Less wind drag — a slim case cuts the resistance and wind noise that a tall box creates at highway speed
  • Clearance — 6.25"-class height clears garage doors, drive-throughs, and trailhead branches that stop taller setups
  • Lower center of gravity — weight rides close to the rack for more stable handling off-road
  • Security — two padlock-adaptable hasps per case, TSA-approved for airline travel when it comes off the rack

Low-Profile Roof Rack Cargo Cases — 38" to 53"

Four lengths, one design: reinforced polypropylene body with ABS latches, steel hinge pins, a dust and waterproof gasket seal, three layers of customizable foam, crushproof handles, and reinforced wheels for the trip between the vehicle and camp. Mount them to roof racks, truck bed slats, or trailer bays — and stack them when the trip is over.

Cargo Boxes for SUVs & Crossovers

Shopping for a cargo box for an SUV? Start with your rack, not the box: measure your crossbar spread and the flat load area between rails, then pick the longest case that fits with the tailgate clear. The 38" case is the most popular SUV and crossover fit; pickups and full-size rigs with platform racks typically carry the 44" or 48". Every case ships with free US shipping and 30-day returns, so you can test-fit at home.

Stackable Cargo for Platform Racks and Trailers

For bulk storage up top or on a trailer deck, the roto-molded SRX cargo cases (50–175 liters) stack vertically and lock down with integrated locking points — a weatherproof, gasket-sealed complement to the low-profile line when volume matters more than height. Prefer metal? Explore the overland aluminum case collection for stackable storage chests.

Roof Rack Storage FAQs

Can you put a storage box on a roof rack?

Yes — Eylar low-profile cargo cases are engineered to mount cleanly on roof racks, crossbars, truck bed slats, and trailer bays, and their slim profile keeps wind drag down at highway speeds.

Will a roof rack storage box fit in my garage?

The 38"–48" low-profile cases add only 6.12" to 6.3" of height above your rack — most garage doors that clear your vehicle with a bare rack will still clear it with a case mounted.

Are roof rack storage boxes waterproof?

The low-profile line carries IP67 waterproof and dustproof protection with a full rubber gasket lining — built for driving rain, dust, and spray at highway speed.

What size cargo box fits an SUV?

Measure your crossbar spread and flat load area first. The 38" case is the common SUV and crossover choice; longer 44"–53" cases suit pickups, vans, and full-size platform racks.
