Features & Benefits

  • Frees up Cabin Space on Road Trips

    Eighteen cubic feet of roof storage swallows family luggage, ski gear, camping equipment, and snowboards up to 84.65 inches long. Passengers actually get legroom on long trips instead of riding with bags on their laps.

  • Dual-Sided Opening

    Open the cargo box from either side of the vehicle, whichever happens to be the curb side or the easier reach. Loading and unloading in tight parking spots stops being a hassle.

  • Torque-Limiting Mounting Knob

    The removable torque-limiting knob prevents overtightening at install, so the box mounts securely without damaging crossbars. A small detail that protects the rest of your roof system.

  • Integrated Tie-Down Points

    Interior tie-down points keep gear from sliding around during hard braking or sharp turns. Your equipment arrives the way you packed it.

  • SKS Lock Security

    Included SKS locks add an extra layer of security so the lid stays closed and your gear stays where it belongs. Useful during overnight stops or any time the car is unattended.

  • Flat Floor Maximizes Usable Space

    An unobstructed flat floor makes it easy to fit awkwardly shaped gear without wasted volume. You actually get the full benefit of all 18 cubic feet.

Love this addition for roadtrips with family

The Yakima SkyBox NX XL is awesome on my Tesla! It adds tons of extra space without ruining the sleek look of the car. I’ve hauled luggage camping gear and even skis with no problem. It’ll take on tough weather just as easily.Pros:✅ Huge 18 cu ft capacity—perfect for family trips✅ Opens from both sides super convenient✅ Solid build and secure locks✅ Surprisingly quiet—even at highway speeds✅ Easy to install on Tesla crossbars✅ Doesn’t feel too heavy for the glass roofCons:❌ Big to store when not in use❌ Range hit (like any rooftop box) but not too badOverall it’s totally worth it if you need more space for your Tesla adventures. Stylish functional and makes road trips so much easier!

Amazing for trips

We love the Yakima Skybox. We are a large family and travel in my minivan. A large family of 8 traveling with a baby we need all the space we can get. My van is equipped with the roof rack so the skybox attaches right away and easily. It held all of our luggage! Not to mention it opens on the box side and comes with 2 keys. It is super easy to install and very light easy for 2 people to carry and attach. By far this is a travel essential.

Great storage space

This is a great product for SUVs installation is very easy and we could fit a lot inside. We are a family of 5 and we were able to travel and pack all of our stuff. We had 3 carryons and some small bags around and we also were able to fit my daughter’s scooter! It’s very sturdy and also water proof we drove 20 hours total and had some pretty rough weather along the way.
