Kia Sorento Cargo Roof Box Buyers Guide

Kia Sorento Roof Box PinterestThe Kia Sorento is a lovely 7 seater SUV. With such a big vehicle, it might be difficult to imagine that you would ever need a cargo box. But you have now found yourself in that position and have landed here.

You are about to go away with an SUV full of people, and what feels like more luggage than an airport has ever seen. So where can you store all this? On your roof, of course!

Between 2002 and 2009, the Sorento manufactured two principal models – one with and one without roof rails. If you don’t have roof rails, then you might also need a roof rack. But it is not essential. 

You can get cargo boxes that don’t need a roof rack to sit on the top of your car. From 2015 onwards, the Sorento had solid integrated roof rails, so all you need to do is find a box that fits on to these.

Usually, the roof load of a Sorento is up to 100kg (220lbs), which is another factor you should bear in mind. You will need to think about the weight of your cargo box and the weight of your potential contents. 

Don’t forget to make sure you take account of any roof-mounted antennas and any navigation fins.

In this post, we look at what the best options are for Cargo Boxes for the Kia Sorento.

Best Cargo Roof Box for the Kia Sorento

The below items are the best product we could find. So let’s take a look at why we love these cargo boxes.

#1 Thule Motion XT XXL Cargo Carrier

Thule Motion XT XXL Cargo CarrierThis spacious, aerodynamic, and stylish roof-mounted box is so easy to use and looks stylish! Available in two colors, with a 610L volume (or 22 cubic feet) it can store everything you and your passengers could possibly need. 

However, if you feel that this is too big for your content, then maybe the 16 or 18 cubic feet box would do. We love the dual side opening, making your gear easy to get to. This model weighs 55lbs.

  • Easy to open/close in all weather conditions
  • Loads of space
  • Grip friendly outer handles and supporting lid-lifters
  • Load capacity remaining about 165 lbs

#2 Golpus Cargo Box

The size of this box is 63” x 31” x 15” so this will sit small on the top of your Sorento’s roof. It weighs 25lbs, so it is much lighter than the Thule. 

It boasts 14 cubic feet of storage space, so you can still take a lot of your essentials away with you on your trip. 

Also, with the dual-sided opening, it is available in three colors: black, white, and titanium grey. 

At the bottom, it has sturdy metal lid stiffeners making the box very stable and secure while you travel. It’s highly durable as it is manufactured from ABS and plastic.

It can withstand all heavy weather conditions. It comes with 4 quick connect anchors to allow for a more straightforward installation process. 

We also loved the super latch security, which ensured that the lid resolutely secured to the base, keeping your valuables safe. This is suitable for square, round, and most aerodynamic bars.

  • Dual-sided opening
  • Great in all weather conditions
  • Load capacity remaining 195lbs

#3 Yakima Skybox 21

This is a good quality cargo box but has a very low load limit considering its size. Offering 21 cubic feet in volume, the load limit is around 34kg. 

Note that the Thule is a smaller size, but has a weight load capacity that is significantly more. 

This product, like the Thule, benefits from dual-sided opening and a super latch for smooth opening and closing.

  • Tool-free installation
  • Fits all bar types
  • Gloss finish could scratch easily
  • Load capacity remaining 146lbs

#4 SportRackHorizon XL Cargo Box

SportRackHorizon XL Cargo BoxWith a volume of 17 cubic feet and a weight of 44lbs, this box has a quick-release attachment kit for easy installation and smooth removal. 

It fits on round and square bars, and most factory racks. 

While it isn’t as sleek as the Thule option, it makes up for that in durability. Accordingly, it is made from impact-resistant ABS material. 

You could also select the Horizon Alpine or L if you feel you need less space.

  • Locks included
  • One side opening only on the passenger side for added safety when opening
  • Load capacity remaining 176lbs

#5 Rightline Gear Sport Carrier

This is a great lightweight choice for those of you who do not have roof rails. Weighing a little under 6lbs, its available at a volume of 9 cubic feet and its size is 36” x 30” x 13-16”. 

It allows you to take a lot of stuff with you. You can see that there is a “Select your vehicle” banner on the top left of the site these links to. 

We found this really useful when checking whether the carrier would fit on our model – just for that added peace of mind. 

This carrier comes equipped with 4 attachment straps, 4 car clips, a stuff sack and a user guide sewed into it. 

We found that this product was easy to install, and the low height of it adds some aerodynamic qualities. The installation only took us a few minutes, and all we had to do was attach the straps to the Sorento’s door frame weather molding.

The coated zipper can be found on the underside of the flap, making this water-resistant and keeping your valuables dry. And just for even more peace of mind, this comes with a 1-year manufacturer warranty.

  • Easy installation
  • Water-resistant
  • Load capacity remaining 214lbs
  • Attaches with or without a roof rack


These are the best cargo boxes for the Kia Sorento. We have weighed up some pros and cons of each so that you can select the best product for you. 

Before you buy, note the layout of your roof and ensure that there is space for the cargo box to sit on top of your car. Remember that the weight of your cargo-box will limit the amount of stuff you can take with you due to the roof load capacity of the Sorento.

At the end of the day, the choice is yours, but our favorite was the Thule Motion

You need to remember that you want something that fits nicely on the roof of your car, can withstand all weather conditions and gives you all the space you need – then you are bound to pick the right cargo box for you.
