  • Compatible Cargo Boxes for Rhino-Rack Roof Rack on a 2016 Volkswagen Golf
  • There are numerous cargo boxes that are compatible with Rhino-Rack roof rack # RRRS605 for your 2016 Volkswagen Golf R. For a box that has the most space and can fit the roof rack you can use Car Top Cargo Rooftop Cargo Box - 18 cu ft - Black Item # CTC-18S. This is an 18 cubic foot box and it is 56-1/2 inches long. The next step down in size is Thule Force XT Sport Item # TH6356B. This box has less space, 11 cubic feet, but it is longer at 74-3/4 inches. And the next size down from...

  • Recommended Bike, Cargo, and Canoe Carriers for a 2017 Chevy Equinox with Factory Roof Rack
  • For your 2017 Chevy Equinox I recommend using the Thule UpRide # TH599000 for your bikes because of how easy it is to use and you don't have to remove your front wheel to transport your bike. To carry your canoe I highly recommend the Lockrack Adjustable Watersport Carrier # 339-LRUNISETX for a few reasons. The first is that it can accommodate pretty much any boat style out there and the second reason is that this carrier has integrated locks that help grip your canoe and eliminate the...

  • Will Thule Force XT Sport Roof Cargo Box Fit on Rola Roof Rack for 2016 Subaru Crosstrek
  • The Thule Force XT Sport, part # TH6356B, does fit the Rola 59898 roof rack; however, that roof rack has been discontinued and is no longer available. We do have the longer 53 inch crossbar Rola, part # RBU53, which the Thule also fits.

  • 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...

  • Lightweight Portable Step for Use with Thule Force Rooftop Cargo Box on Tall SUV
  • You are correct that the size and weight of heavy-duty steps like # S-150 and # SASXLA-09C-G make them less than ideal for transport inside a rooftop cargo box like the Thule Force XT # TH6356B. Odds are if you are using a roof box you do not have space in the vehicle to store one of these steps. Handy as they are their best application is as an entry step for folks towing a large trailer such as a 5th wheel that has substantial cargo storage space built-in. But anyone using a rooftop...

  • Roof Rack and Cargo Box Recommendation for 2019 Toyota Corolla
  • For your 2019 Toyota Corolla I recommend the Rhino Rack roof rack part numbers # RRVA118B-2, # RRRLKVA, and # DK383. I really like the Rhino Rack roof racks as they give you a higher quality roof rack but at a better price than the more expensive brands. Then for a smaller cargo box the Thule Force XT part # TH6356B would be a great job. It can hold up to 11 cubic feet is a confirmed fit and is very well made.

  • Kit Needed to Swap Lock Cores Out of Thule Force Cargo Box
  • You can use a Thule Re-Keying kit part # TH450200 which comes with two new cores, two keys, and a change key. But to remove the old lock core will require you to unlock it first. Once unlocked you can insert the change key and the old core will slide right out. If you don't have a key to unlock what you have you'll need a key for it. To pick out the key you'd then want the part # THKEYNXXX where the X's equal your key number.

  • Is Rhino-Rack 2500-Series Roof Rack Compatible with Thule Force Cargo Box # TH624
  • The Rhino-Rack 2500-Series roof racks can include either square Euro crossbars, their Vortex Aero bars or their heavy-duty rectangular bars. The Euro square bars and the Vortex Aero bars both are fully compatible with the Thule Force XT Cargo Box # TH6356B. The heavy-duty cross bars # RB1250 are not. The Thule Force XT requires that the spread between the crossbars be at least 23-5/8-inches. As long as the rack has this minimum spread and uses one of the two compatible bar types it will...

  • Adding Kayak Carrier and Roof Box to Rhino-Rack Pioneer Platform
  • The Thule Force XT Sport Cargo Box # TH6356B measures 24-3/4 inches wide and the Rhino-Rack J-Style Kayak Carrier # S512 will take up about 24 inches of crossbar space when it's in its upright position for a single kayak. This width might increase if you have a larger kayak that requires you to adjust the J-cradle down a bit. Both of these mounted side by side will get you extremely close to if not over the 49 inch overall width on your Rhino-Rack Pioneer Platform Rack like # JA9133....

  • Recommended Best-Value Rooftop Cargo Box for 2017 Subaru Outback Wagon
  • Perhaps the best overall value in a rooftop cargo box is indeed one of the Thule products, their Force XT cargo box # TH6356B. This box offers 11-cubic-feet of internal capacity and a manageable box weight of only 32-lbs when empty. Locks are included and the Force installs quickly thanks to Thule's Quick-Grip mounting clamps, also included. Thule is great about standing behind their products with service and replacement parts. You might consider a simple accessory for use with the box,...

  • Recommended Roof Rack and Rooftop Cargo Box for 2017 Volvo XC90 With Flush Mounted Rails
  • I would be happy to get you exactly what you need. To do so, I would first need to know if your 2017 Volvo XC90's roof has side rails on top that are raised or if they are flush to the roof (basically, if there is a space underneath the rails on top of your roof or not). If you can get back to me with that info I can get you exactly what you need.

  • Measuring to Determine Which Thule Cargo Boxes Fit a Lexus RX 350
  • Front overhang for cargo boxes is not an issue of concern. Longer boxes will overhang the front some but most boxes have adjustable feet to allow you to have the box more forward or rearward on the vehicle roof. The area of concern is the back of the vehicle. Things like antennas and rear hatch doors can interfere with the cargo box. In order to determine which Thule boxes will fit without interference you will need to take one measurement. First, if the crossbars on your Lexus RX...

  • Will the Thule Force XT Cargo Box Fit a 2010 Toyota 4Runner without Hatch Interference
  • I checked with Thule and on a 2010 Toyota 4Runner there will be interference with the rear lift gate if you were to use Thule Force XT cargo box # TH6358B. The largest box that you can use without rear hatch interference is the medium box # TH6356B. Going with the smaller box will be the way to go.

  • 16 Cubic Foot Roof Cargo Box Recommendation by Thule
  • The Thule Force Cargo Box part # TH6356B is the 13 cubic foot Force cargo box. The 16 cubic foot version of this cargo box is the # TH6357B. I confirmed this by checking with Thule. Or another option you have for a 16 cubic foot cargo box would be the Pulse L part # TH615.

The linked page displays all roof rack fits for each of the two ways a Cherokee roof can be configured, either a bare roof with no fixtures or a roof that has raised front-to-back side rails like yours.

  • Roof Cargo Box and Kayak Carrier Recommendation to Fit 2019 Toyota Highlander with Factory Rack
  • We have the Thule Force XT part # TH6356B which is 24-3/4 inches wide and has 11 cubic feet of cargo space. This would easily be narrow enough to also accommodate a kayak carrier. For that we have the Thule Hullaport part # TH848 which is a J-style. This rack is padded, easy to load/unload, can fold down when not in use and could potentially carry a second kayak if needed. These both are a confirmed fit for the factory bars of your 2019 Toyota Highlander as well. The cargo box would...

  • Comparing the Thule Pulse and Force Alpine Cargo Boxes for an Audi A4
  • The Thule Pulse Alpine cargo box # TH613 is the new economy, entry-level box. It opens on one side only, is constructed of durable ABS plastic, and has easy-grip mounting feet that mount in about 5 minutes. The Force XT, # TH6356B, is a step up from the Pulse. It features a diamond textured aeroskin for added durability. It is more sleek and aerodynamic. This box uses tool-free quick-grip mounting feet. The lid opens on either side. The Pulse is 11 cubic feet and 88-1/2 inches long whereas...

  • Will the Thule Transporter Cargo Carrier Interfere with the Rear Hatch on a 2013 Mazda CX-5
  • We have not had a chance to test the Thule Transporter Combi Cargo Carrier, # TH665C, with a 2013 Mazda CX-5 yet, but I did speak with my contact at Thule who said you should have no problem opening your rear hatch with this carrier tilted. The Transporter can tilt to a 45 degree angle away from the vehicle. As far as exhaust is concerned, we will want to do some measuring to see if they will be a problem. Constant exhaust heat can harm the carrier since the carrier is made of a plastic...

  • Recommended Roof Rack and Roof Box for 2015 Nissan Versa Note

  • Will an Enclosed Cargo Carrier Interfere with Backup Camera and Sensors on 2011 Infiniti QX56
  • Due to the location of the backup camera and sensors, the Rola Swinging Enclosed Cargo Carrier, # 59109, and all other enclosed cargo carriers will interfere when backing up. Like your QX56, most vehicles with backup cameras and sensors are located in the bumper and around the lift gate handle. Because enclosed carriers install in the trailer hitch, they block most of that area. The only way to use an enclosed cargo carrier and have full use of your backup camera and sensors is to use...

  • Will Thule Force Alpine # TH623 Clear Rear Antenna Fit of 2014 Toyota 4Runner
  • I looked up pictures of the antenna/fin you have on the rear of your 2014 Toyota 4Runner and it only appears to be slightly taller than the top of the roof rack crossbars, so the tapered rear of the Thule Force XT part # TH6356B would pretty easily clear above it. If you check out the picture I attached you can see that the rear of the box angles up compared to where it mounts to the crossbars.

  • Which is the Smallest Roof Mounted Cargo Box that will Fit 2010 Infinit EX35 with Factory Crossbars
  • We have an option that will work for you, however, Yakima does not list any of their cargo boxes as a fit for your 2010 Infiniti EX35 factory roof rack. Yakima does not have any options, however, Thule offers quite a few, the smallest being the Sidekick, part # TH682 and the Force XT Sport, part # TH6356B. The Sidekick measures 54 inches long and the Force measures 74-3/4 inches long. According to Thule, these cargo boxes will fit on your factory crossbars so drilling new holes will...

  • Recommended Cargo Box and Kayak Carrier for a 2011 Toyota Yaris Hatchback with 48 Long Crossbars
  • I have some options for you but since you only have 48" wide crossbars and you will be using an awning you are pretty limited in what you can use. I recommend the Thule Force XT Sport # TH6356B as it measures 74-3/4" long x 24-3/4" wide x 16-3/4" tall and only requires 48-1/4" of front crossbar to rear hatch clearance (see attached photo). If you use this cargo box with the Thule Stacker # TH830 (which carries the kayak on its side) then you may have enough side-to-side clearance to...

  • Will Thule Evolution 1600 Cargo Box Clear Antenna and Hatch on 2014 Mazda CX5
  • The Thule Evolution cargo box has been discontinued since 2007 so I do not have any fit information on it. But I can tell you how to figure it out. First, there were two types of Evolution cargo box. One had just drilled holes for the mounting feet and the other had slots with more adjustability. In either case you will measure from the center of the forward most mounting foot position straight back to the furthest part at the back of the box. Then with the front crossbar as far...

  • Roof Cargo Box Recommendations for a 2007 Toyota Highlander
  • The most popular Thule cargo box for 2007 Toyota Highlander owners is the Motion 22 # TH6299B. This is a very large box with 22 cubic feet of storage space. It is a higher end option. The second most popular Thule box is the Force XT # TH6357B. This box is smaller with 16 cubic feet of storage space. Following that we have the Force XT, # TH6358B, at 21 cubic feet. But if you do not need a box that large the Force XT Sport, # TH6356B, at 11 cubic feet is a great choice.

  • For your 2016 Acura MDX with factory installed cross bars the Thule Force XT Rooftop Cargo Box # TH6356B is a confirmed fit and a great value. This fits as long as your two factory crossbars are spaced at least 23-5/8-inches apart from the center of one bar to the center of the other and no than 35-3/8-inches apart. You'll want to take a look at your MDX owner's manual for the car's roof weight capacity. Keep in mind that the weight of the box itself plus your loaded cargo needs to remain...
