Video Transcript for Yakima OffGrid Roof Cargo Basket Extension Review

This is what the OffGrid Basket looks like without the extension. And this is what your basket looks like with the extension piece. Hey everyone, it's Evangelina at etrailer, and today, we are taking a look at our 18-inch extension for the Yakima OffGrid Basket. This is the 40-inch wide extension, and it adds 18 inches of length. So, that's for the medium OffGrid Basket. If you have the large OffGrid Basket where it's 49 inches wide, that's going to be a separate extension part.

As you can see, with the extension installed, this fit seamlessly with your current basket. So, you have the same design, the same metal construction, the same black powder coat finish. You also have the ability to use the clamps underneath the extension piece or with your original bars, and you get the accessory bars on top. Now, while this increases the amount of cargo space you have, it does not increase your cargo capacity, and that's because you're still limited to 165-pound weight capacity. In fact, the extension piece for our medium size adds 12 and a half pounds.

So, add the weight of your carrier, add the weight of your roof rack, add the weight of your cargo, (hands tapping) and make sure it doesn't exceed your vehicle's capacity. So, this encases the length of your medium basket from 44 inches long, all the way up to 62 inches long, there's no in between. You also have where you can move the accessory bars to a different crossbar spread, and this fits the crossbar spread of your vehicles differently as well. Check out our product page for our full kit, where we put down all of those different numbers, that way, you can compare with your own vehicle if this will fit your crossbar spread, as well as your accessory bar spread needs. So, the first thing (metal shuffling) you're gonna do, is you wanna get your old OffGrid Basket, and uninstall it.

Now, if you lost (component clinking) the tools from your original basket, the kit includes the tools, you're gonna take this apart to get the hardware inside. So, there's those four bolts on the side rails, as well as the bolts underneath. So, once you take the last bolt out, (bolt clinking) you are then able to pull apart your basket, (component clinking) and grab those plates or brackets. We're moving to the garage floor for more space, because now, we have the extension piece. (metal clinking) So, the hardware you took off earlier, that's gonna go to one side, the new hardware included with your extension piece, that's gonna go to the other side of your old OffGrid Basket.

So, I start by just (metal clinking) lining it up with those side rails. (metal clicks) And then, we're gonna fit our brackets in and through. (brackets clinking) (component shuffling) (metal clinking) With the bottom brackets in place, flip it over, so you can do the side rails. (metal shuffling) There's two pieces. There's the bottom receiver, (component shuffling) and then the top bolt. Now, do that for all of the four connecting pieces. (component clinking) With all the connector pieces tightened down, and your brackets tightened down, you can now move your crossbars if you want to, where it will fit your accessory. So, here I have a friend, Aiden to help me out. Begin the basket up and onto the roof. (basket clinking) If needed, (basket shuffling) you may need to move your clamps to match your crossbars. If your crossbars have less than a 27-inch crossbar spread, (metal shuffling) you are going to have to move one of the clamps to the extension. (clamp shuffling) (clamp clicking) That right there was a look at the 18-inch extension for the Yakima OffGrid Basket. You can also find it as a full kit, or as an extension piece separately here at

Great extension for the offgrid medium rack, works great


Loving the free and super fast shipping . Order a medium Yakima off grid with extension for my 2021 Highlander


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


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


Super great job and even received my order sooner than promised! Awesome job!


I had the Yakima off grid basket. It just wasn't big enough, so I bought the extention.

Unfortunately the extension doesn't fit together well. The original basket was tight, snug and didn't rattle at all. Since adding the extension kit, the basket rattles and is not snug. The new connectors appear, visually, to be the same as the original, but they are not. I had requested new hardware and only received the screws, not new brackets.

I'm kind of disappointed considering the price of the original basket and the extension kit...


Super fast shipping and came in a really nice box! The yakima extension looks pretty nice too!!!


Item arrived quickly and as advertised. No complaints at all.


Fast delivery part in stock fair price

  • 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...

  • 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...

  • 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...

  • 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.

  • 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...

  • 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.

  • Does Yakima OffGrid Medium Cargo Basket Fit 2019 Toyota Tacoma With Factory Roof Rack
    That's a good question, so I checked directly with Yakima for you, and the medium OffGrid cargo basket does indeed fit your 2019 Toyota Tacoma with the factory roof rack, so long as you get the 18 inch extension for it.

  • 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 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 # Y53TR 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 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...
