Thule SUP Taxi XT Crossbar Requirements

Thule Motion XT Alpine Alpine 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 Alpine has 16 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 Alpine Alpine Construction

This cargo box is constructed of durable ABS plastic that is lightweight yet rigid and impact resistant. It has a glossy black, 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 Alpine Alpine Cargo Box Dual Side Opening Lid

The Motion XT Alpine 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 Alpine Alpine 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 Alpine Alpine 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.

Average Customer Rating:  4.8 out of 5 stars   (33 Customer Reviews)

90-1/4 x 37-1/2 x 13-1/4. Roof box mounts to your crossbars with PowerClick clamps. Locking lid opens from either side of your vehicle. Great for carrying skis, snowboards, and other gear on sedans and crossovers. Durable ABS plastic construction.


Great customer service and great product. Thank you !



The Box has been a great help for us and has withstood the test of time ! No cracks no damage still looking brand new after a year of use in the sun and snow and high winds on the roof of my cars. I highly recommend this box and all Thule parts and accessories!


This roof box is very sleek in design and I love how low it sits. Everything is wonderful with it; it can fit all my camping gear despite being a slimmer model. I gave it four stars because one of the powerclick clamps that it came with fell apart only after 3 uses and now i’m going to have to drop another $70+ for a replacement. Other than that, I would recommend this item.


Sleek and super easy to install. Love that you can unlock and load from either side of the box. etrailer was amazing to work with. Shipped quick after I purchased and had for an upcoming beach trip.


I like the low profile and being able to open it from both sides. I wish the bottom were flat; it's hard to lay skis down on the binding for tie-down without them flopping over. Cannot mount on 2019 Jeep GC with factory roof rack without tailgate hitting it; wish there were a bumper option of some sort.


Looks great and works well with Yakima Whispbars on my 2014 Audi S4


Looks sexy on our Kia Telluride! Wanna go camping?
Thanks for the no shipping cost.


Everything was delivered to my garage as expected, safely packaged and loaded at my house, the Thule motion alpine is great looking and sturdy , I trust it with my skis, e-trailers free shipping beats everyone else charging $150++.”, and they kept me notified via email of shipping and tracking , great people to order from .



It’s the best thing I could have bought for taking my skis etc across country


The carrier arrived sooner than expected and was in excellent shape. The new clamp system made attaching the carrier to the factory installed roof rack of my Toyota Highlander a breeze. Other reviewers indicated an increase in wind nose but I have not noticed such an increase. This is a replacement for an older Thule carrier that only opened from the rear and was a painful installation process. Looking forward to enjoying my alpine cargo box for many years to come.


We're very happy with the quality and capacity of the cargo box. After driving with it the past few days, it's had a surprisingly negligible effect on our fuel economy.



This Thule cargo box meets our needs perfectly. Its high quality, easy to install and take down, and provides lots of supplemental storage space.


Great customer service! The quality of the product is outstanding!
Emailer rocks it!!


I love this Thule cargo box! Very spacious and easy to clean. I receive compliments all the time!


The carrier is very long but not very tall (looks like a TNG space coffin for those of you star trek fans). Because of the extreme low profile it’s quiet and doesn’t drag down the mpg, but I do have trouble using it for some of our bags and suitcases. I even had difficulty with the sleeping bags being too tall. I smushed them a bit to get it closed, but then it wouldn’t lock. The key won’t come out if it’s not locked, so wasn’t worried about it falling out while driving, but it definitely diminishes the functionality…. It’s really my own fault as I didn’t realize that this one seems to be more designed for skis and the like instead of other family cargo that tends to need more height.


Love the look on my 21 Acadia!


Item has minors scratches on cargo box. Overall the delivery date and tracking was awesome!

I will have our customer service team reach out to you.


Love this box, its perfect to move around all of our water skis and gear for the lake in the summer. Bought with the Thule multi lift to store on the ceiling in the garage so I can install with one person. No regrets.



Awesome product. Dont use very often, but lota of extra space when we need it. It is low profile, so even on our Expedition, we still clear all the parage garages we have encountered at beach condos.


Nice, low profile, fits in a standard-height garage on top of an SUV. It would have to be loaded outside but I could at least park it back in the garage overnight before a trip. Opening it is a little rough at first because it feels like it's getting stuck somewhere but I'm sure that'll smooth out with more frequent use. Have driven it also, seems pretty secure, no rattling, minimal noise.


The customer service was outstanding. Communication was A++. The shipping was fast. Would definitely buy again and recommend.


Came ahead of schedule, all in one piece! Looks better than expected, actually. Very glad I got it!


Can't beat free shipping. Product was delivered as promised and easily installed.


Easy, quick, and great pricing. Thanks for making it so easy

  • How Many Snowboards Can I Fit in the Thule Motion XT Alpine
    The Thule Motion XT Alpine # TH629506 is designed to carry between 3-5 snowboards, so the odds that you'll be able to fit 4 are pretty good; but this is obviously going to depend on the size of the boards and bindings. The internal dimensions on this box are 84-1/2" long x 33" wide x 11-1/4" tall, so as long as you don't have any extremely long boards this box should be able to handle 4 boards without issue. In the configuration you're mentioning you'll need to make sure that your bindings...

Your cross bars can be no wider than 3-1/2" or taller than 1-11/16". The bars need to be spaced between 23-5/8" and 36-7/8" on center and the measurement from the front cross bar center to the roof line where rear hatch door meets must be 55" for your rear hatch not to contact the cargo box when opening.

    I have a great solution for you. Even though we do not have pictures of bags/luggage inside the Thule Motion XT # TH629506, we do have the interior dimension to give you the definite measurements that you would be working with.

  • How Much Height Does Thule Motion XT Alpine Box Add to Vehicle Roof Rack
    I can tell you how much height the Thule Motion XT Alpine part # TH629506 would add to the roof rack of a vehicle (13-1/4 inches) but I do not have a way to determine what your current vehicle and roof rack height would be so you'd need to measure and then add 13-1/4 inches to determine the overall height.

  • Does Thule Motion XT Alpine Fit 2020 Toyota RAV4 with OEM Crossbars
    The Thule Motion XT Alpine # TH629506 is a fit for the factory crossbars of your 2020 Toyota RAV4 with OEM crossbars. To determine if this would allow your rear hatch to open you'd need to take one measurement. You'll need to measure from the center of the front crossbar to the rear hatch and if that dimension is more than 55 inches you'd be able to open the rear door.

    It looks like you've already done all the measuring you need, so the Thule Motion XT Alpine Rooftop Cargo Box # TH629506 will work just fine with your 2019 Subaru Impreza. This cargo box only requires that you have a minimum crossbar spread of 23 5/8" but no more than 36 7/8" apart. Since you have a maximum crossbar spread of 33" you're good since you're within those parameters. If you have the hatchback and want to be able to open the hatch without interference you'd need to make sure...

  • Does The Thule Motion XT Alpine Rooftop Cargo Box Fit OEM Volvo Crossbars On 2020 Volvo XC90?
    I confirmed with my contact at Thule that the Thule Motion XT Alpine Rooftop Cargo Box - 16 cu ft - Black Glossy # TH629506 will fit the OEM Volvo crossbars on your 2020 Volvo XC90. This is a really nice cargo box which has an integrated lock to secure your belongings. The weight capacity for this box is 165lbs, but you will want to make sure you do not exceed the weight capacity of your vehicle's roof which is typically found in the owner's manual. I attached a demonstration video for you.

  • Is The Thule 16 Cubic Foot Cargo Box Compatible With My 2015 Subaru Outback With Factory Crossbars?
    The Thule Ascent is no longer manufactured so I cannot say if it will fit or not. Compatibility with roof cargo boxes all comes down to crossbar spread. Usually with stock crossbars on your 2015 Subaru Outback most boxes will fit. I'm going to use the Thule Motion XT # TH629506 as an example because it is very similar to the Ascent. The Motion XT needs a crossbar spread at least 23-5/8ths and no more than 36-7/8 inches. This is the measurement between the center of the front crossbar to...

    The Thule Motion XT Alpine, part # TH629506, is compatible with factory bars. So, it should work for the ones on your 2015 Toyota 4Runner. Of course, there is a way to be absolutely sure. You can measure the width and height of your crossbars to make sure they fall within the range of the Motion XT Alpine. The maximum dimensions they can accommodate are 3-1/2" wide and 1-11/16" tall.

Otherwise I'm not seeing that Thule has a 3012 key so to get the locks working on your Thule Motion XT Alpine Rooftop Cargo Box # TH629506 you need the Thule One-Key System Lock Cylinders # TH450200 which comes with 2 new lock cores and keys as well as the universal change key used to...

Now if you meant the Thule Motion XT Rooftop Cargo Box - 16 cu ft # TH629707, it will probably have enough rear hatch clearance.

I noticed you also looked at the Motion XT Alpine # TH629506, which is also a 16 cu/ft box that will fit on your factory crossbars.
