75-1/2 x 35 x 16. Free up space inside your vehicle and carry gear on your roof with this cargo box. NX nano-texture finish is scratch-resistant. Dual-opening lid provides easy access from either side of your vehicle. Clamps mount to most crossbars.
Features:
Specs:
The SkyBox NX lid opens from both sides so you can easily access cargo from the driver's side or passenger's side of your vehicle. If you are parked on a busy street, in a tight parking lot, or even next to a campground picnic table, you have the option of opening the lid from the side of the vehicle that works best for you.
The fortified lid has an easy-access edge and spring-loaded hinges that allow for smooth, one-handed operation. Also, since the lid is extra-stiff, it helps reduce road noise and vibration. Finally, it has a nano-texture finish that helps guard against dings and scratches when you're on the road or when the box is in storage.
The SkyBox has security latches on both sides to ensure the lid is completely closed and locked. This system prevents you from removing the key from the lock unless all 3 internal latches are engaged. That way, you are prevented from removing the key and driving off with an unlocked box. Also, the SKS lock core can be swapped out to make all your Yakima gear keyed alike.
The SkyBox installs with mounting clamps that slide along tracks in the floor of the box. These clamps fit most crossbar styles and they adjust for different crossbar spreads. To adjust the clamps, loosen the knobs with the included torque tool and slide them to the desired location. Then, tighten the knobs and close the clamps around your crossbars.

Arrived Friday for Memorial Day weekend. Was looking forward to using it for a camping trip but, could not get either side to unlock. Tried both keys numerous times. No luck. Have to wait until Tuesday to call customer service. Not Happy.
Safely delivered without damage. Lauren at etrailer.com made this a very smooth transaction! Thank you!
I hate writing ratings, BUT, this product is great. The finish on the product is very impressive.
Delivery….the driver called several hours before delivery to give me an estimated delivery time, kept me posted and was wonderful. Etrailer products are great.
Highly recommend
This box has served us well. It was subjected to a few heavy rainstorms and stayed dry. Fairly easy to mount by myself. Definately need to keep after it for UV protection as it will fade. Was a good purchase.
Installed Yakima SkyBox NX 18 as advertised. Fit vehicle (Outback with factory bars) perfectly. Careful not to open the clamps to much during first install. You might scratch or dent your roof. Would be good if 3/16 hex wrench was included for horizontal adjustment of bar clamps. Will see it the hinges and fasteners stand the test of time, but it looks like Yakima has a well thought out product.
Love it! This thing is massive! It fits a ton of gear.
The unit arrived in good condition! Thank you!
I consulted with Josh to confirm my order and discuss some of the details on fitment. He answered them all! Skybox NX 18 arrived on time and in perfect condition. 2023 Hyundia Santa Fe Hybrid Limited.
Well designed, love it...
Fit perfectly, no wind noise, didn't even know it was on the roof. No loss of mpg. Good quality easy to install.
This is my first box. I have been using bags previously. Man I wish I upgraded sooner. This was a breeze to install, even with the aftermarket Prinsu roof rack. Just had to slide some bars around, and I got a really nice low profile install.
We are thrilled with our purchase! Ordering from etrailer was a pleasure and saved us over $160 in shipping costs. The packaging provided excellent protection and there was not a mark on our roof box. The Yakima SkyBox NX 18 is a welcome addition to our 2023 Jeep Grand Cherokee L. The fit on our vehicle was perfect and the 18 cu ft. capacity of the box is impressive. We were able to fit a 3 piece luggage set (Full Size suitcase, Carry On, and small roller bag) as well as a jogging stroller for our 3 year old. Highly Recommend A++
Excellent box and installation is a bre eze!
The cargo box arrived quicker than expected and was in excellent condition.
Awesome service from E-Trailer. Super fast shipping and great communication regarding the delivery from the freight shipping company. Cargo box is well built and functions flawlessly. Nice product and nice fit on top of Infiniti QX80. Thanks E-Trailer!
Performed perfectly on 28 hour round trip at interstate speeds. There's nothing more I could have asked from it. I was a little late when I realized I needed this box and the only place I could have gotten from in time was etrailer. Everything worked out and I was so relieved!
Purchased for my 2023 Honda Pilot with factory crossbars. The cargo box is an excellent value compared to other products in this size range. It can easily hold our soft luggage for a family of 5. I also find the locking mechanism and hinge design very thoughtful - I'm confident the carrier is fully closed and locked. I also like the integrated torque wrench clamps; they are very low profile and I'm confident the box isn't going anywhere. Yakima should include straps at the price point.
Great experience with etrailer. Skybox was shipped in a plastic wrapped box and strapped to a wooden pallet so it arrived in great shape. Pricing from etrailer was good and the free shipping made the deal. Attached the box to the 4runner and it looks great.
Excellent service and advice on the order.
Enjoyed the review of setting the box on the car in the video.
Great information on the product delivery and tracking information.

Bought this to replace a Sears box (I think was made by Thule). Like that it opens from either side for installation. The old one required Gorilla arms to tighten.
3 things- & I wish they had a 4.5 star option… I would have given that .
#1- this is the BEST roof box( for me )I have ever seen/ owned and I’ve had Thule pulse and Force boxes and other Yakima’s . I like the textured finish - looks rugged and speak at the same time. The metal tubular frame on interior really helps with the rigidity of the ABS plastic. The lever opening and closing is very nice especially because it clicks when closed so your not jamming the key hoping all guides are lined up like in the Thule pulse.. also the squareish lines match my 2nd gen Tundra wonderfully
#2- etrailer has always been a Go Too for me mainly due to their excellent customer service . Their response time is excellent and the team is very knowledgeable and eager to help.
#3- only reason for the non 5 star review is shipping took 7-8 days longer than expected … which threw a wrench in personal travel plans… I ordered this item through etrailer and not Yakima due to expected delivery date… didn’t work out. However the item did arrive in excellent condition when it arrived .
If you’re reading this review to see if The Sky Box NX is worth the money then hell yes it is …& would I purchase it again through etrailer… probably ;) they are great people and feels good to support them.
I used the SkyBox and the added storage space on top really helped alleviate the cramped feeling we would have had in the car. The two sided opening also made packing and unpacking significantly easier than single side toppers. My only complaint is The installation tool could be a bit more ergonomic, but that's a nitpick and it's better than any other install tool I've used anyway. With a growing family, we've been running out of space in our Traverse when driving to and from vacation. The SkyBox lets us move nearly all the luggage on top of the car, freeing up more room inside. This is perfect for anyone with a need for extra storage!
