Thule 635S Sonic XL Silver Cargo Box

While you will want to take some measurements of your bag, any of the Thule XL (or XXL) boxes would be would be a great pick. XL size Thule boxes have 17 cubic feet of space and about 17 inches of height depending on the box. Just make sure to measure the distance from your rear roof bar to your open hatch (if you have one) to make sure it will clear. If you have any questions on that call or email us at Rack Attack.

If you drive an SUV or van, probably not. Be sure to measure the total height of the vehicle with the Thule 635S Sonic XL Silver Cargo Box installed, and keep that information handy (on the inside of your sun visor is a great place). Running into your garage will, unfortunately, void the box's warranty.

While the weight limit of your roof rack may differ, cargo boxes can hold up to 165 pounds.

As long as your vehicle is equipt with the crossbars (side to side) then all of our cargo boxes will attach directly to the rack. If you have a rear hatch, make sure to measure how much room you have and compare to the box length to make sure the hatch won't hit the box when opening. If you don't have crossbars, you will first need to add those prior to adding in a cargo box.

No! Any tools required for installing this rack product come included in the box!
