Mounting Diagram

Hyper XL

The luxurious Thule Hyper XL cargo box is the perfect way to carry outdoor equipment such as skis and snowboards, as well as large luggage or baby gear for 3 - 5 people on your roof rack crossbars. The long, spacious box provides enclosed storage for your gear on long road trips or when traveling to sporting events.

AcuTight Mounting Hardware

Mounting the Hyper XL is a 5-minute operation thanks to the pre-installed AcuTight hardware. Just throw the box on your roof, center the clamps over your crossbars, and turn the hand knobs located inside the box to tighten them down. The knobs will click once they are appropriately tightened, ensuring that the box is secure every time you mount it on your roof.

These hand knobs are mounted in tracks so that they can be repositioned for vehicles with shorter roofs. Simply slide the hand knobs to the desired position and give them a spin.

The AcuTight assemblies also include 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.

Aerodynamic Design

The Hyper XL is designed to be extremely aerodynamic with Thule's patented, dimpled AeroNose and Hi-Flow Base. The pointed nose reduces drag by up to 35 percent when compared with boxes that have standard shapes, and the dimples reduce drag and wind noise 10 percent more than boxes without dimples. The flat base has channels that let air pass easily between your roof and the box, further reducing drag while also maintaining your vehicle's fuel economy.

Dual-Side-Opening Lid

The Hyper XL features a dual-side-opening lid so you can access and load your gear from either side of your vehicle. The rugged lid is reinforced to ensure that it remains easy to open and close over years of use. The lid is arched to match the roofline of your vehicle, and 2 built-in straps make it easy to lift and close the lid.

Integrated Light

This premium cargo box offers an integrated light inside so it's easier to load and unload cargo at night. The light turns on automatically when the box is opened and shuts off when the box is closed, and the single LED is strong enough to illuminate the entire length of the box.


The cargo box has oversize SecureLocks on each side. These specially designed locks prevent you from removing the keys if the box is not properly closed and locked. This eliminates the possibility of the box coming open as you travel down the road. And the locks include Thule One-Key-System cores so you can swap them out to make all your Thule accessories keyed alike.

Rear-Angled Base

The Hyper XL features Thule's patented rear-angled base. The undercut back of the box is designed specifically to prevent interference with your vehicle's trunk or hatch door. This means that you can load and unload your cargo area without having to remove the box from your roof.

Rugged Construction

This cargo box lid and base are constructed of reinforced, ultra-thick ABS plastic that resists impact, weather, and harsh UV rays. The additional internal reinforcements offer a more stable, quiet ride than standard boxes. There is also an anti-torsion rib built into the lid that helps the box to resist lifting and pulling forces that could cause it to contort over time. The rib ensures that the lid holds its shape so that it's always easy to open and close. And the two-tone, high-gloss automotive finish and "X" design add a touch of class when the box is mounted on your roof.

Video Transcript for Thule Hyper XL Rooftop Cargo Box Review

Today were going to be taking a look at the Thule Hyper XL Rooftop Cargo Box with 17 cubic feet of space, in two-tone black and silver, part number TH612. The Thule Hyper XL has a carrying capacity of 17 cubic feet, with a weight capacity of 110 pounds. Its made of a rugged 5-layer ABS plastic with an acrylic cap that resists impacts, weather, and harsh UV rays. The Hi-Flow base of the Thule Hyper allows air to pass between the vehicle and the box, reducing drag and maintaining fuel economy. Another unique feature of the Thule Hyper XL, is that it features a dual-side-opening lid. This is going to allow you to easily load and unload your cargo from either side. Also featured on the AcuTight mounting hardware, are these little slots installed onto the clamps. What these slots are designed to do, is using the two included straps, you can feed these straps through these little grooves, and then bring those straps around your gear. If you have any skis or snowboards, or maybe any delicate items that might be moving around when youre driving down the road, these straps are going to help secure all that gear, so that nothing gets damaged or broken. The Thule Hyper features the Thule One-Key System lock cores.

Since the lid opens from both sides of the box, there is a lock core on each side of the box. The key can only be removed in the locked position, and the key can only be in the locked position if all of the latches are engaged correctly. Another neat thing about the Thule Hyper, is that when you open up the lid on the box, you can see in the back corner is this nice, bright, LED light. This LED light is going to make it much easier when youre loading your gear, or unloading your gear, when its dark outside. The LED light turns on when the lid is open, and then turns off when the lid is closed. Another neat thing about the Thule Hyper XL is that the patented rear-angled base at the back of the cargo box, which is specially designed to give you clearance when youre opening your rear hatch. For taller vehicles, or higher SUVs, theres this included strap thats going to help you be able to pull-down the lid if you cant actually reach it, or if you dont have a stool or ladder.

This strap is in easy reach. You can just simply pull-down and close the lid. Well go ahead and show you how to install it. Well just simply place the box up onto our roof rack crossbars. You want to be careful because directly out of the box, the claws are all the way tightened. You can loosen them up.

Im going to keep them closed, so if I get caught or snagged on a crossbar, then I dont bend the clamp. Well simply unlock the box by turning the key, and well open the lid. I can see we're on the inside of the box, and there are four knobs, two knobs on each side. When you pull the box directly out of the storage box, you can see the clamps are actually tightened all the way, so were going to need to loosen up the knobs, which are on the inside of the box, which is going to open up those claws. Loosen those up, and then you can see, now the claws are open. Well just go ahead and close the lid, and then well move to the other side of the vehicle, and then just repeat the same process. Now that we have all four clamps loosened up, Im going to close the lid.

Thats going to give us a little more stability when were positioning the clamps around our crossbars. Im just going to go ahead and lift up the box, and just position these clamps on those slots on the bottom of the box, that way we can position the clamps to fit over the crossbars. Now that we have the clamps positioned over the bars, Im going to kind of come back at the rear of the vehicle and push it forward. Im going to try to be able to get access to the rear hatch. Looks like Im going to have enough space. Now that I know how far forward it needs to be, it just comes down to do I want to install it on the passenger side of the vehicle, or the drivers side of the vehicle The majority of people are going to install it on the passenger side, because the passenger side is the curbside, where when you pull up to the street, youll be able to load and unload your gear safely from the sidewalk, or off of the street. Go ahead and open up the box and tighten down the clamps. With those two clamps tight, well move to the other side of the vehicle and tighten down the two remaining clamps. You can see the clamps, which go around the crossbar, then on the inside of the box, are the knobs. They all come preassembled, already installed on the box. When you turn the knobs to tighten down the clamps up against the bars, the knobs will actually make that ratcheting noise, and that indicates that the clamp has been fully tightened, so theres never any question about if youve tightened it enough, or if its too loose. That way youre 100% secure that the box is fully secured to your roof rack. Well go ahead and load up some gear. Now that we have all of our gear loaded up, well go ahead and take it out for a test drive to show you how it looks. That will complete todays review of the Thule Hyper XL Rooftop Cargo Box, part number TH612. .

Do you have a question about this Roof Box?

  • Rooftop Cargo Box Recommendations for 2017 Subaru Outback
  • All rooftop cargo boxes will generate wind noise and to some degree all will negatively affect mileage but those with the more aerodynamic low-profile shape, such as Thule's Hyper XL # TH612, will tend to be quieter and will have slightly less effect on fuel economy. At 90-inches external length this is the longest box Thule recommends for your Outback. It can handle skis up to 201-cm in length so it may be more than you need. It also weighs 53-lbs empty so keep in mind that what you can...

  • 2018 Volvo V90 CC Ocean Race Roof Cargo Box Recommendation
  • Probably the closest Thule Cargo Box to the one Volvo sells is the Thule Motion XT Alpine Rooftop Cargo Box # TH6295W which is white and has similar cut outs where the mounting hardware is. It's not a total match though as the rear is shaped differently. This will fit the factory bars of your 2018 Volvo V90 though which are Thule bars. To determine if this will allow your rear hatch to open will require you to measure from the center of your front crossbar back to the hatch seam. If...

It also requires 51-1/8 inches between the front crossbar and the line where the roof and hatch meet to confirm there won't be contact with the hatch and you will have full access to your rear cargo. Thule does not confirm the fit, so I recommend taking the measurements to see if...

  • Reducing Wobbling on a Thule Excursion Roof Top Box.
  • There are a few things that you can do to ensure a fit, and approach the wobble of your existing box without making a purchase. First, you'll want to make sure that your crossbar kit is spread out as far as the mounting system or crossbars will allow. This will give the roof box a better platform to rest on while driving, and reduce its wobble. Next, when you load the roof box, you'll want to make sure that less of the weight is put into the front of the box, and put more into the...

My technical contact at Thule informed me that sometimes the flush rails are a bit thicker at the front of the vehicle which does raise your rail a bit. She said it is typically less than an inch. She also told me that your vehicle has been tested with the AeroBlade Edge Crossbar # TH7602 and she believes your installation is correct. We discussed...

This has a cargo weight capacity of 165 lbs and will carry skis or a snowboard with a maximum length of 175 cm. This box weighs just 41 lbs.

  • To find out if you can use the 53"Thule WingBar Evo Crossbars # TH711420 with the Evo Foot Pack # TH710401 on your 2017 Subaru Forester, you will need to do some measuring. If the center to center distance of the side rails on your Forester's roof is no less than 35-3/4 inches, then the 53 inch bars will work for your application. If your measurement is less than that, then you will need to use the 47 inch Crossbars # TH711220. If you do not have factory installed rails on your Subaru...
