Features to know about

Excellent Blend of Style and Function

Yakima CBX Geometric StylingYakima CBX Geometric Styling

Most roof boxes add storage, but not style. The premium CBX blends seamlessly with modern SUVs, featuring edgy, geometric styling with a high-gloss exterior that'll turn heads for all the right reasons. Unlike outdated, clunky designs, it enhances your vehicle's look instead of taking away from it. In fact, it looks so good, you may rethink covering it with stickers.

Low-Profile Build, Big Storage Inside

Yakima CBX low profile with plenty of storageYakima CBX low profile with plenty of storage

The CBX's low-profile build isn't just about looks - it's about smart storage. Inside the box, the surface is flat with no large knobs sticking up, maximizing every inch of space. That means skis, golf clubs, and road trip essentials fit just as well as they do in taller boxes - minus the extra height. And when it's time to take it off your vehicle, the lower height makes it more convenient to store in your garage or against a wall.

Secure Tie-Down Points

Yakima CBX secure tie-down points

Inside, built-in anchor points on the crossbar clamps give you a secure spot to attach tie-down straps (sold separately), keeping your gear from shifting on bumpy roads. No more unpacking a jumbled mess when you arrive - just grab your gear and go.

Clamp, Tighten, and Go

Yakima CBX clamping knob

Installing the CBX is a breeze with the included tool. Just line up the clamps with your crossbars, tighten them down, and you're set - no over-torquing, no crossbar damage. Forget hunting for wrenches or second-guessing - just clamp, tighten, and hit the road.

Dual-Side Access for Safer, Smarter Loading

Yakima CBX access on both sidesYakima CBX locks on both sides of the lid

The CBX makes unloading easier - and safer - especially if you have to pull to the side of the road or get stuck in a crowded parking garage. The lid opens from either side, so you can grab your gear without stepping into traffic. And when you stop for a bite, locks on both sides keep everything secure, so your gear stays right where you left it.

Order, Delivery, Assembly and Installation smooth and very straightforward. You definitely need a second person to mount unto Car Rack on my Tesla Y. Whole process from delivery to mounting took about 1 hour. Opening latch on side required more force initially than I expected.

  • How to Tell if Thule Motion 3 XXL Will Fit OEM Roof Rack on a 2023 Acura MDX
    Hey Mike, thanks for reaching out! The Thule Motion 3 # TH59PN requires 54-3/4" from the front crossbar to the line where the roof and hatch meet for your 2023 Acura MDX hatch to open up without interference. I'm not sure what your measurement is, but if it's at least 54-3/4" then you're good to go! If it's less than that, you'll need to use the Yakima CBX XXL # Y73QD instead. It has less clearance requirements and Yakima has confirmed it will fit with the OEM roof rack on your MDX. Both...

  • Will the Yakima SkyBox NX XXL Fit a 2019 Honda Odyssey with OEM Crossbars?
    Hey Von! The feet of the SkyBox NX XXL # Y43QD will fit (see photo from Yakima site), but the box will be too large for your 2019 Honda Odyssey, so we'll need to either get the smaller SkyBox NX XL # Y45AV, or you can go with the CBX XXL # Y73QD if you're still wanting the larger capacity. The CBX has a different box design which is why it physically fits and the SkyBox NX doesn't. Were you more interested in the design and price-point of the SkyBox NX, or are you more interested in...

  • Comparing Yakima CBX and SkyBox NX Internal Box Dimensions
    Hey Matt, thanks for reaching out! Here are the internal dimensions for those cargo boxes you asked about, as well as a snapshot of the whole file that Yakima has on their website (and a link to it!) concerning box sizing: - Yakima CBX LG # Y63QD - 77" long x 29" wide x 12" tall - Yakima CBX XXL # Y73QD - 85" long x 28-1/2" wide x 14-1/2" tall - Yakima SkyBox NX # Y93QD - 80" long x 18-1/2" wide x 13" tall - Yakima SkyBox NX XXL # Y43QD - 80" long x 29" wide x 13" tall Let me know...

  • Can Yakima CBX XXL Roof Cargo Box Carry Skis/Snowboards
    Hey Will, yes the Yakima CBX cargo box part # Y73QD can carry up to 5 pairs of skis or snowboards that are up to 185 cm in length. This is a larger sized box but would that be enough for you?

  • Do Yakima Cargo Boxes Have Locks Integrated into Them
    Hey Evaldez, yes all of the Yakima cargo boxes you mentioned # Y63QD, # Y73QD, # Y93QD, and # Y43QD have locks integrated into them to prevent theft. There is actually a lock on both sides too.

  • Do Yakima Roof Cargo Boxes Have Weight Capacities
    Hey Denny, Yakima cargo boxes like the part # Y63QD, # Y73QD, # Y93QD, and # Y43QD don't have stated weight capacities which means as long as you stay under the weight capacity of the vehicle's roof rack you'll be fine. Worth mentioning is that Yakima roof racks are rated for 165 lbs so if you wanted a hard number I would go with that.

  • Are There any Special Tools Needed to Install Yakima CBX Cargo Box
    Hey Casey, the install of the Yakima CBX XXL part # Y73QD is not difficult at all and does not require any tools to complete. The hardware easily is operated with one hand to tighten around the crossbars.
