At 21 cubic feet the Yakima SkyBox 21 Cargo Box has the largest cargo capacity that Yakima offers.

Thanks to the quick-installation hardware, it mounts onto your crossbars in a matter of seconds without any tools. It opens on either side, so you’ll never have to do laps around your vehicle to get your stuff. And it has a nice, low-key matte black finish.

• Weight: 62 lbs.
• Dimensions: 92x36x18"
• Capacity: 21 cu feet. Varies by application. Fits crossbar spreads of 24" thru 42". See Yakima Fit List for specific vehicle information.
• Q: What is the box made out of?
• A: ABS Plastic. We use ABS instead of fiberglass because it is lighter and less expensive, while still being really strong (=maximum value). Light weight is important because the lighter the box is, the more weight you can put into it.
• Q: Will it fit on my factory rack?
• A: We have done extensive testing on factory racks to see which ones are strong enough to handle a luggage box. We have also redesigned the mounting hardware to fit a variety of different crossbar shapes. Look in the Fit List to see if the SkyBox boxes are options in the list of accessories for your vehicle.
• Q: Will it fit on my vehicle?
• A: Different vehicles have different capacities. We need to consider weight capacity, crossbar spread, wind lift and other factors to answer that. Look in the Fit List to see if the SkyBox boxes are options in the list of accessories for your vehicle.
• Q: Can I drill new mounting holes in my gear box?
• A: This is not a good idea. The mounting holes in all of the gear boxes are positioned to optimize durability and compatibility with appropriate crossbar spreads. Drilling holes to mount a box in some other way could compromise its design, not to mention, void the warranty.
