Video Transcript for Review of Yakima 18" Extension For OffGrid 44" x 40" Roof Cargo Basket - Y07108

Hi, everybody. Andy here with And today, we're gonna take a look at this 18 inch extension for the Yakima OffGrid 44 inch long by 40 inch wide roof cargo basket. If you would like to upgrade the capacity of your 40 inch wide Yakima OffGrid roof basket, then this extension is exactly what you are going to need. This custom extension adds 18 inches of length to your Yakima OffGrid roof cargo basket. And for your reference, I am including our item number to that specific basket on your screen, so you can be sure that that is the basket that you have.

And this is going to be an easy installation between the two main pieces of your basket. It will secure with the included hardware that you see here along with the included Allen wrenches. And this extension is constructed of a durable, sturdy steel with a powder coat that will resist rust and corrosion. Now, let me retrieve my tape measure here and just give you some overall measurements. Now, this is right about the longest point here, so this is where we're gonna get our 18 inch measurement.

So, 18 inches long if you can see that there. And then the overall width, we are gonna be sitting right at 40 inches wide. And then the overall height, we're sitting right at about 5 1/2 inches tall if you can see that there. Yeah, right about 5 1/2 inches tall. Now, this weighs about 12 1/2 pounds itself.

And I do wanna mention that the Yakima OffGrid roof cargo basket has a weight capacity of 165 pounds. And adding this extension does not increase that weight limit, but it will increase your basket's storage capacity by about 40%. And this does have a limited lifetime warranty. Well, that's gonna conclude our look today. I do hope that it was helpful for you.

Again, my name is Andy. Thank you for joining me..

Upgrade the capacity of your 40" wide Yakima OffGrid roof basket with this 18" long extension. Just slide the extension into the tubular bars of your basket and secure with the included hardware and Allen wrench. Sturdy steel construction.


Adds room, meshes nicely and didn’t change the minimum crossbar distance for mounting the rack.


Installed onto 2018 Subaru Outback. I recommend the extension for this car, it has a long roof and this looks great on it.



Ask the Experts about this Yakima Accessories and Parts

  • Yakima OffGrid Basket Extension Weight Limit
    Those are good questions. I will answer your last question first. You are correct, the limiting factor is the weight your crossbar and car combination are rated to carry. If something has a higher weight limit than the 165lb weight capacity the rack is rated to carry the rack's weight limit will still be the limiting factor. Please keep in mind this weight limit is a combination of the racks weight, the weight of the accessory, and the weight of the item/s you are transporting. Now for...

  • Will The Yakima OffGrid Roof Cargo Basket Still Fit a 2020 Acura MDX With the 18" Extension Kit?
    Yes, the 18" Extension # Y07108 that fits the Yakima OffGrid Roof Cargo Basket # Y07138 will fit and still allow for your 2020 Acura MDX to use the back hatch. With the extension you will need to have a crossbar spread of 30-38" to secure the basket to your crossbars. I have linked a video with the OffGrid Basket mounted on a 2016 MDX and you can see that there is still plenty of room both in front and behind the basket. If you do not have any crossbars for your MDX, please let me know...

  • Does Yakima Offgrid Carrier Fit OEM Crossbars of Subaru Outback Wilderness
    The Yakima Offgrid part # Y07138 that you referenced would fit the factory crossbars of your Subaru Outback Wilderness with or without the additional extension part # Y07108 that you also mentioned. The extension price is available at the attached link. Your sunroof may open still with this rack installed but you'll find that the wind noise created would make you want to keep it closed.

  • How To Attach Ski/Rod Carrier to Cargo Basket
    If you wish to use both a ski/rod carrier and a cargo basket I do have options for you but you'd need a certain type of cargo basket, one that lets you mount crossbars on top so you can then attach the ski/rod carrier. The Yakima OffGrid Roof Cargo Basket part # Y07138 is a great option for this that comes with the accessory bars needed to mount a ski/rod carrier like the Rhino-Rack Ski and Fishing Rod Carrier part # RR572. There's also an extension available, the 18" Extension for Yakima...

  • Roof Basket Bike Rack Combo With An Off-Road Look
    I also like the Off-Road look. You can use this Yakima OffGrid Roof Cargo Basket # Y07138-08. It's 62 inches long with only one extension # Y07108. It has accessory bars # Y07354 that helps organize cargo but you can also put a bike rack like the Yakima HighRoad # Y02114 on the bars! Both the basket and the bike rack are adjustable to fit each other, your bike and factory roof rack on your 2010 Toyota Highlander.

  • Roof Rack For 2019 Nissan NV200 Van With A Naked Roof
    If you're looking to get a roof rack for your 2019 Nissan NV200, you don't need to purchase side rails because you can bolt a roof rack directly to the roof. All you need is the Yakima JetStream Crossbars # Y00425 the SkyLine Towers # Y00148 and the Landing Pad # Y00248. This is a much more cost effective way of getting a roof rack on your roof. Since your van is relatively long, you can get this Cargo Basket # Y07138 and this extension # Y07108 to really maximize what your NV200 can haul...

  • Will Yakima OffGrid Cargo Basket Fit Thule WingBar Evo Crossbars On a 2018 Subaru Crosstrek?
    Yes, the Yakima OffGrid Roof Cargo Basket # Y07138 will fit on the Thule WingBar Evo Crossbars # TH711420 and Feet # TH450R for your 2018 Subaru Crosstrek as long as you have a crossbar spread of 24"-32". The OffGrid is designed to fit elliptical crossbars like your AeroBlade as well as factory, round and square crossbars. We do offer the 18" Extension # Y07108 as well as the Accessory Bar # Y07353 that will fit with this Basket.

  • Best Trailer Hitch & Roof Racks for a 2014 Ford Taurus
    The trailer hitch that I recommend going with for your 2014 Ford Taurus is the Curt # C13379 which is a Class III hitch that has a 2" receiver. You'll be able to use a wider variety of hitch accessories with a Class III receiver. I like the brackets and thicker powder coat on this Curt over what comes on the Draw-Tite which is why I recommend the Curt. If you don't already have a bike rack then I highly recommend the Kuat Transfer V2 # KU24FR which can carry up to 3 bikes and has a U-Shaped...

  • Comparing Thule Canyon XT vs Yakima OffGrid Roof Basket for 2020 Tesla Model 3
    As a petite 5'2" Ecuadorian girl, I can totally relate, so I'm happy to make a recommendation! Based on my research, your 2020 Tesla Model 3 factory roof rack system has a crossbar spread of 28 inches. This means that both the Thule Canyon XT # TH859XT and the Yakima OffGrid # Y07138 are compatible with the factory rack on your Model 3. Both roof baskets have the capability to accept a variety of roof mounted accessories. The Yakima OffGrid actually has two adjustable accessory bars, which...

  • Comparing Yakima OffGrid and Thule Canyon XT Baskets for 2017 Jeep Grand Cherokee
    Both the Yakima OffGrid # Y07138 and the Thule Canyon XT # TH859XT roof baskets are compatible with round, square, aero, elliptical, and most factory crossbars and both feature comparable weight capacities: 165 lbs for the OffGrid and 150 lbs for the Atlas. That being said, the quick installation and huge versatility make the Yakima OffGrid the clear choice. When it comes to space, the Yakima OffGrid Roof Cargo Basket is 44 inches long by 40 inches wide but there is an 18 inch extension...
