Thule SUP Taxi XT Crossbar Requirements

Thule Motion XT XL Cargo Box

Cargo boxes, bags, and baskets are great for transporting gear on your vehicle's roof. A cargo box has the added benefits of an aerodynamic shape that reduces drag and wind noise, a hard shell to protect your gear, and a higher degree of weather resistance. And you can latch and lock a cargo box for added protection against theft.

The Motion XT XL has 18 cu ft of storage space for golf bags, luggage, skis, snowboards, and other gear. The aerodynamic, low-profile design helps to reduce drag and wind noise, and the locking lid conveniently opens from either side of your vehicle. The box has internal tie-down points for securing cargo, and the PowerClick mounting system offers easy, tool-free installation.

Durable Construction

Thule Motion XT XL Cargo Box Aerodynamic Design

This cargo box is constructed of durable ABS plastic that is lightweight yet rigid and impact resistant. It has a glossy silver, gel-coat finish that is stylish and less susceptible to chips, scratches, and harsh UV rays when compared with paint.

Dual-Side-Opening Lid

Thule Motion XT XL Cargo Box Dual Side Opening Lid

The Motion XT XL features a dual-side-opening lid so you can load and access your gear from either side of your vehicle. Integrated, grip-friendly handles help you easily open and close the lid even with one hand. The lid has lifters that ensure it opens and closes smoothly. There is also a convenient pull cord on the inside that helps you close the lid.

SlideLock System

Thule Motion XT XL Slide Lock System

The cargo box has SlideLock locks on each side of the lid. These locks have built-in indicators that let you know if the box is properly latched. The keys cannot be removed from the locks unless the lid is closed and locked. This prevents you from driving with an open or unlocked lid. The locks include Thule One-Key-System cores so you can swap them out to make all your Thule accessories keyed alike.

PowerClick Mounting System

Thule Motion XT XL Cargo Box PowerClick Mounting System

The box can be mounted on your vehicle in less than 5 minutes with the PowerClick mounting system. These clamps adjust along tracks in the floor of the box to accommodate different crossbar spreads.

Thule Motion XT XL Cargo Box Dials

To install the box, set it on your roof rack and center the clamps over your crossbars. Then simply turn the dials to tighten the clamps around the bars. The dials click when the clamps are secure.

Cargo Tie-Down Points

Thule Motion XT XL PowerClick Assembly

The PowerClick assemblies on the inside of the box have fixed anchor points for securing your cargo. Just loop the included cargo straps through the anchor points and pull the straps tight to secure your gear.

Video Transcript for Thule Motion XT Rooftop Cargo Box Review

Speaker 1: Today we're going to be taking a look at the Thule motion XC rooftop cargo boxes. They're available in 16 cubic feet, 18 cubit feet, and 22 cubic feet in either black glossy or titan glossy. With this box, you're going to be able to carry your skis, luggage and snowboard on the outside of your vehicle, and look cool while doing it. All three boxes have a great capacity. You're going to be able to carry three to five snowboards, five to seven pairs of skis, or a combination of luggage, skis and snowboards.With the 16 cubic foot, you're going to be able to carry skis up to 175 centimeters long. With the 18 cubic foot, you're going to be able to carry skis up to 200 centimeters long.

With the 22 cubic foot, you're going to be able to carry skis up to 215 centimeters long. The pull strap makes it super easy to close, and it's lockable so you don't have to worry about your gear going missing when you're grabbing a burrito. It's easy to open, even when you've got your gloves on. There's plenty of room to get in there and slide the latch.One thing I like is you're never going to have to worry about if your box is closed all the way or not. The red indicator goes away when your box is closed all the way.

The key won't come out unless it's properly locked. Now, a lot of the higher end boxes are going to be able to open from either side. This one's no different. Still, it's a great feature to have.With the gear removed, we can check out some of the stuff here on the inside. Now, on your lower end roof boxes, you're going to have a U bolt style clamp that's going to be difficult to operate.

You're not going to want to be taking it on and off. The toy motion uses power click knobs that are easy to operate. When you hear the click, you know it's tight. The coated clamps keep your cross bars looking new. It's got six anchor points, so you can strap down your gear.

Everything is going to arrive in one piece.Now, most roof boxes are made out of plastic. This one's made out of a durable ABS, so it's not as flimsy as some. Some older roof boxes sacrifice aerodynamics and style for size. Thule has incorporated all three. The high gloss finish is going to give you style, and the shape is going to reduce wind noise and drag. All three sizes have a weight capacity of 165 pounds, though you'll want to be sure and check with your vehicle's owner's manual to see if it can carry that much. Customers on our site compare the Thule motion to the Akima Skyboxes. The Thule motion has more of a high profile design, whereas the Akima Skybox has more of a medium profile. Finally, the motion XT is available in silver and black, whereas the sky box is only available in black.Now that we've gone over the features I'll go ahead and show you how to get it installed. This is going to work with your round, square, arrow, elliptical and most factory roof rack systems. Let's go ahead and set it in place. If you need to get an extra set of hands, go ahead and do so. You'll want to be sure and center it up, and position it so that you can still access your rear hatch. We're all set here.With our box open, let's go ahead and snap our clamps in place. Then we can tighten it down. Check out from underneath. You can see our clamps tightening around our bar. When we hear three clicks, that's how we know it's properly tightened down. Once you've loaded up your luggage and skis, you're going to want to run your included straps. There are three. Then we can just close it up. Then you can lock it up and you're ready to hit the road. That's going to complete our look at the Thule motion XT rooftop cargo boxes.

Review from a similar Thule Motion XT in Roof Box

Great for loading or unloading from both sides. Keeps cargo bone dry unless you open lid to load while raining. Holds all luggage for 5 people to free up interior of Outback for pets and people. Glad I made the purchase. Only knocked the fuel economy back by 2 miles per gallon. An acceptable tradeoff. 666951

Review from a similar Thule Motion XT in Roof Box

Great product. I installed it on my 2018 Lincoln Navigator with no problem. Took about 15 minutes start to finish. Mounts directly to the factory OEM rack. I just used it to haul 5 pairs of skis, ski boots and two large luggage bags... it still had some room to spare! 594489

Review from a similar Thule Motion XT in Roof Box

Great Product! It fits my Chevy Traverse like a glove. I wouldn't want anything bigger. It easily holds two large suitcases plus a couple of smaller duffel bags. Attaching it to the car crossbars takes only minutes and the locking latch to open it is amazing. It makes the car about 7'-4" tall. I forgot about it and drove through a 7'-0" parking garage and hit the ceiling. It flex enough that it didn't break but I still wouldn't advise trying it for yourself. 490062

Do you have a question about this Roof Box?

  • Quality Comparison Between Thule XT Roof Cargo Boxes and Malone Cargo Boxes
  • When it comes to overall quality, design, and ease of use you really can't beat Thule cargo boxes like the Motion XT part # TH6298T or the Force XT part # TH6358B. Thule has been making cargo boxes for a very long time and over the years they've kept raising the bar for how nice the boxes can be. They are expensive for sure, but they are the best you can get. The Malone Profile18B Rooftop Cargo Box # MPG911 is a solid value for a solid box, but at this point you already spending quite...

  • Comparing Thule Motion XT XL and Yakima ShowCase Rooftop Cargo Box
  • What creates wind noise is mostly the crossbars on your vehicle and both the Thule Motion XT XL and Yakima ShowCase are highly aerodynamic and streamlined so the best way to choose between these two rooftop cargo boxes is by their respective features. The Yakima ShowCase is available in Black # Y07328 or Silver # Y07329, has 20 cubic feet of carrying capacity and fits crossbars that have a spread between 24" and 40". It is a high-quality cargo box but I recommend going with the Thule...

  • Roof Mounted Cargo Box Fits for 2015 Audi Q5
  • Assuming your Q5 has roof mounted crossbars, all the Thule roof mounted cargo boxes would work on your vehicle, as long as the bar spread (center to center distance between the front and rear crossbar) can be adjusted so that the bars are between 23-5/8 and 35-1/2 inches apart. However, the longer boxes could prevent you from fully opening your rear hatch without hitting the back of the cargo box. According to Thule, the largest box that'll fit on your Q5 without interfering with...

  • Roof Rack Recommendation for 2018 Lexus RX 350 For Thule Hyper XL Cargo Box
  • I checked with Thule and as long as you install a roof rack like the Thule Aeroblade Edge part numbers # TH7602B-TH7602B and # THKIT4072 on your 2018 Lexus RX 350 F-Sport the Thule Hyper XL part # TH612 will fit and work great. The Motion XT XL # TH6298T that you mentioned is also a fit but since you really wanted the Hyper that's what I would go with. The Aeroblade Edge roof rack I mentioned is a great option too that I recommend as well because it has aero shaped bars that will be...

  • Differences Between Thule Motion XT Cargo Boxes TH6297T TH6297B and TH6298B
  • The difference between the Thule Motion XT part # TH6297T and # TH6297B is the color of the paint. The part # TH6297T is a glossy gunmetal gray color whereas the part # TH6297B is a glossy black. The part # TH6298B is the larger, black version of these boxes at 18 cubic feet compared to the 16 cubic feet of the other boxes. The part # TH6298T is the gray version of this as well.

  • Does the Thule Motion XT XL fit onto the Thule AeroBlade Edge Crossbars on a 2016 Toyota 4Runner?
  • The Thule Motion XT XL, part # TH6298B, is compatible with the Thule AeroBlade Edge, part # TH7503-TH7503. The clamps inside the Motion XT will clip to the roof rack and you can move the AeroBlade Edges to match these clamps position inside the box. When you mount the roof box and load it, make sure that you are within your roof's factory weight limits. For the 2016 Toyota 4Runner, this is 132lbs with an evenly distributed load. Subtracting the weight of the box and crossbars, this...

  • Using the Thule Motion XT XXL Cargo Box on a 2017 GMC Acadia Limited
  • The Thule Motion XT XXL, part # TH6299T can fit onto most factory crossbars, thanks to its incredibly flexible clamps. These are shared across the Motion cargo box line. However, the spread of your crossbars will need to be measured. You'll measure from the center of the front bar to the center of the rear bar. All boxes will have a certain range of crossbar spreads that they will fit. Another concern is with how well it lets your rear hatch operate. You can verify the fit prior...

  • I can help you find alternative Cargo Boxes that give you the clearance you need. There is not a way to add towers to the factory roof rack on the 2019 Subaru Outback Wagon to carry the Yakima SkyBox 21 cubic feet part # Y07337. The Box fits the roof but the rear cargo area hatch cannot open fully with the box on the roof. I recommend the Thule Motion XT 18 cubic feet part # TH6298T.

  • Will a Yakima SkyBox Fit a 2017 Hyundai Santa Fe with Factory Roof Rack
  • I checked with Yakima and they do not recommend the use of any of their roof boxes for use on the FACTORY roof rack on the 2017 Hyundai Santa Fe. The issue is that the Yakima mounting hardware cannot get tight enough on the factory bars. If it is an aftermarket roof rack then they would be fine. I also checked Thule and they do have options for models that have the factory roof rack. They specifically recommend the Motion line: # TH6297B or # TH6297T for 16 cubic feet # TH6298B...

  • The Thule Motion XT in Black Glossy # TH6298B or Titan Glossy # TH6298T should fit and work just fine on the OEM roof rack you have on your 2013 Land Rover Range Rover Sport. These were tested to fit the Thule aero-style crossbars so as long as your crossbars aren't larger than 3-1/8" wide x 1" tall you are good to go. Typically the biggest advantage an aftermarket roof rack has over the OEM is weight capacity. OEM roof racks usually have a lower weight rating so upgrading to aftermarket...

  • I checked with Thule and all of their cargo boxes are a confirmed fit for the factory crossbars of your 2014 Audi Allroad including the Motion XT part # TH6298T that you referenced. This is one of the nicest roof boxes available so I don't think you'll find a better option.
