This kayak rack offers the ultimate in carrying performance. With its 4 boat capacity and proven universal mounting system, The Stacker is the most efficient way to carry multiple whitewater kayaks.


We needed a better way to haul around 3 kayaks and after looking at a number of options, we settled on the Thule Stacker setup. Installation is simple and the stackers provide a sturdy option for hauling multiple kayaks. One of the best features is that they fold down when you don't need to use them.

My shopping experience with etrailer was smooth and shipping was prompt.



Its been a year and were still enjoying the Stacker setup. We have been hauling around our kayaks to local lakes every other weekend or so, and have had no issues. I have been double checking the hardware and occasionally do have to tighten a mounting knob or two. Im happy that we made this purchase and hope to continue using them for years to come.


My wife uses these to carry two small kayaks in the roof of her Subaru. They work great and we very happy with the purchase. She also likes finding her car easier in the parking lots, even with the carriers folded down.



No issues after a year would definitely purchase again.


Looked everywhere to find a kayak rack that would fit on an existing 08 Xterra with a manufacturer storage rack and crossbar support. etrailer site had what I needed. They had a "blog" describing that this would work, with extension bolts (which they also supply). Received the system within 4 days, installed it in about 15 - 20 minutes on the manufacturer rack. Holds up great, first trip we traveled about 250 miles round trip with two kayaks on top (about 80 lbs total), in 20 - 30 mph winds. No problems at all. I am extremely happy with this system. I do use a few rubber cabinet liners cut and placed on the crossbars to help the kayaks from sliding (this is also very helpful). I have read a few reports of the boats coming lose, but have not had any issues. I have enclosed a few pictures to show how they install as well as how boats were secured.


Basically easy to use but roof racks are always a bit awkward to put on and tighten. Was able to transport 3 10ft kayaks on a 2011 and 2017 Subaru Outback with factory racks. My only issue is the clipping ratchet tie downs that come with the rack, the clip is small and often gets caught on the nylon handles on the kayaks. The Grove is sharp and can get tricky to unhook. I personally traded them out for the simple open hook on the racket.



Thule stacker works excellent to carry 3 kayaks on a subaru outback.


This is an easy to use rooftop system. I don’t regret my purchase and would recommend it to others looking for a simple to use system.


Time will tell, but so far so good.


These were easy to install and use. I do recommend this carrier for multiple kayaks transport.

Sue C.


Do the kayaks sit directly on the Thule cross bars? Do you for see a problem rubbing, since there doesnt appear to be any type of padding between the kayak and the rails?

Tim B.


The kayaks sit on the Rhino Rack bars and against the Thule carrier stems and rubbing is not an issue because they should have direct contact anyway. The straps keep them tight to the carrier stems and rack barsno padding needed. This was the best system for us!


This is a well built system. This was laced onto a 2011 Toyota Highlander with factory rails. It is difficult to tell when the hardware is “tight enough” since the attachment clamps bend and conform to the shape of the rails. Since the Thule Stacker is deigned to hold up to four kayaks, there is no cradle to hold kayaks in place(expect some slipping when driving). To mitigate the slipping as well as piece of mind when tightening down the clamps, I purchased some neoprene rubber sheets to place under the kayaks as well as under the clamps to improve grip on the rails.


They Work Well, but Depending upon your position of the roof racks you may get wind whistle if you don't have the kayaks up there, otherwise with the kayaks it was great easy to use and mount on my Rhino Rack, wish they had a front wind cover that would mount and prevent wind Whistle.

They definitely worked well with 2 kayaks up there, I will be trying with 3 in July.


The Stacker worked perfectly! We needed to haul 2 kayaks, and when we began to suspect that my 2014 CR-V cross rails weren't wide enough for the Thule J-Style carriers I kept looking. Well, The Stacker was the perfect solution.
Mounted in the center of the rails, to accommodate two Kayaks. Watching the video provided on etrailer page was very helpful, as we have never tried to use anything like this before.
These brackets are so very sturdy, and with kayaks attached, were so stable. The straps provided were sturdy too, and easy to use.
Being able to use these two brackets, instead of having to buy two sets of J-style hooks was a huge money saver.
Thanks to I was able to figure all of this out, using descriptions, reviews, videos and Q&A's available as I was trying to work out a solution. Thank you etrailer.


great product well documented installation instructions. Durable and kayaks are secure. Only negative is the roof rack clamp created a leak in driver side window that I have made a few adjustments but a slight leak continues.


This company has great with customer service. I’ve bought a few things from them now. They seem like a very hands on company. I bought a thule roof rack and thule kayak stacker from them and the products were best price and as advertised. I will keep doing business with them


Great product. Explanation of what we needed before we bought the product was excellent! Have loaded 4 kayaks easily for a couple trips. Very happy we purchased this instead of a trailer. Easy to take on and off and light to use on both vehicles allowing us to carry on kayak trip so we do not leave kayaks while retrieving other vehicle.

Sherri M.


Great. Easy to install and Uninstalled when not using. Have even used for camping supplies.


Perfect - perform as expected.


I would not buy this item again. Very hard to hold 3 kayaks on top of my SUV using this item.


This carrier allowed me to easily carry 4 kayaks, it was easy to install and even easier to use. The etrailer team was also very easy to work with, following up a few days after rack arrived to ensure I was able to install and see if I had questions. They also provided the same support and follow up on the trailer hitch that I purchased before too.


Love this stacker rack! Wanted to get something that can carry 1-6 boats, and it works perfectly! Folds down nicely on the roof to fit in the garage when not in use. Carries up to 4 boats on my Chrysler Town & Country; up to 6 on the bars of my buddy's pop-up camper roof (extra straps are required for more than 2 boats). Durable, as are pretty much all Thule products. Would highly recommend!


These are easy to install and fit the car without issues and look great. I purchased these to use with a Thule kayak rack and they fit perfect.


The picture shows the stacker in the down position. Very easy to install and raise to tie the kayaks to the two upright Stackers. After you remove the kayaks, simple to loosen a knob and lay the stackers flat so that you don't hear any wind noise when you are driving. Or you can just remove them until the next time you go kayaking. This allows us to carry two of our plastic river kayaks. If we buy another set of the Stackers, we can carry a total of 4 river kayaks.


Installed on 2015 Subaru Outback...holds 2 kayaks safely and securely. Easy to use once you get the hang of positioning the kayaks where you want them and using the straps.


Kayak rack works great with 2 kayaks.. Easy to install.

Roger C.


Works great, no problems with this product.


Good information on site. There are photos of the installation which help a lot. The product is working well to transport two 10’ kayaks on roof rack of 2015 Subaru Outback.


Received the rack on time as promised. Unfortunately UPS smashed the box and repacked it. eTrailer responded immediately and sent a replacement. The rack fit my 2011 Santa Fe perfectly and worked as advertised.
I highly recommend eTrailer for their products and customer service.


I purchased this for my son and friend, and told me it works great. It is easy to attach, fold down when not in use, and takes up very little space when storing. It made a great gift, as well as making loading and unloading simple and easy.


Excellent item arrived as promised. Nice sturdy and compact design looks like it will handle everything that I can throw at it. Looking forward to putting this to good use just like my other Thule products. is my first go to for a great shopping experience.

  • Will My Thule Kayak Carrier Fit the Crossbars on the Malone MicroSport XT # MPG460XT?
    It really depends on the particular model of Thule kayak carrier you are trying to attach. The Thule Stacker # TH830, for instance, will easily install onto the 1-1/4 inch wide x 1-1/4 inch tall square crossbars of the Malone MicroSportXT Trailer # MPG460XT. However, in order to confirm for sure that your particular model will fit, feel free to respond to this answer with the model of Thule kayak carrier you own.

  • Recommended Carrier for Two Kayaks on 2016 Subaru Outback
    Assuming your wife's 2016 Subaru Outback has a roof rack there are carriers that will allow her to carry two kayaks, but the Rhino-Rack J-Style Kayak Carrier # S512 only holds one kayak. To carry a two kayaks I recommend the Thule Stacker Kayak Carrier System # TH830 because it is easy to use and comes with the necessary tie-down straps and bow stern tie-downs for both kayaks. The only thing you may need are Hood Anchors # Y07416, but that is only if your wife's Outback does not have...

  • Recommended Roof Rack That Can Work With A Kayak Carrier For 2004 Mazda Tribute
    Rhe Thule Ride-On Adapter part TH532 has been discontinued but will only work with bike carriers. This adapter uses plastic mounting hardware and cannot handle the stress a kayak would have and would fail. You will need to either install a roof rack designed to be able to handle the weight and stress, or if you have crossbars already on your Tribute you can find a kayak carrier that will fit your crossbars. If you do not have a kayak carrier and you have factory crossbars on your Tribute,...

  • Can Roof Rack On 2006 Jeep Liberty Sport Accommodate 2 Kayak Carriers
    The Thule Roof Rack system for your 2006 Liberty will work great on the side rails you have. For this system you need part # TH712400, and part # TH710401.Thule also lists a 150 pound weight capacity with this system on your Jeep. To be able to carry 2 kayaks on the roof may pose a problem due to the room. Using the Thule Hull-A-Port J-Style Rooftop Kayak Carrier, part # TH834, it is recommended you do not attach the carrier to the portion of the crossbar that sticks outward from the...

  • Which Thule Kayak Carrier Can Carry 12 Foot Long Kayaks
    The Stacker can carry up to 4 kayaks as long as they are 10 feet in length or less but since your kayaks are 12 feet you can't use this rack unfortunately. You'd have to use J-style kayaks like the JayLow part # Y04073 for each kayak as these do not have length restrictions. Be sure to check the weight capacity of your roof and roof rack and be sure not exceed this figure with the weight of your kayaks and carriers. The Y04073 weighs 13 lbs.

  • Roof Rack to Carry 2 Kayaks on a 2009 Ford E-350 Sportsmobile Van
    To add a roof rack to your 2009 Ford E-350 Sportsmobile Van that is tall enough to clear the solar panels you are going to need some gutter feet that are relatively tall. The best rack for your van is the TracRac ladder rack, part # TH29055XT. The gutter feet cause the bars to sit about 7-1/2 inches from the roof. To hold the kayaks I recommend the Thule Stacker # TH830. This is a great way to carry multiple kayaks a roof rack. It includes all the necessary straps to secure the kayaks...

  • Which has More Cargo Space with Seats Folded, a 2007 Ford Freestyle or 2007 Chrysler Town&Country
    I wasn't sure what years to look up so I did 2007 which was the last model year for the Ford Freestyle. On it, with the seats folded down I was able to find that the cargo space is 47.4 cubic feet. A 2007 Chrysler Town and Country has a maximum cargo volume of 129 cubic feet. It was unclear how many seats would have to be folded down or removed to get to that number though. With all of the seats in place it drops down to just 23.5 cubic feet.

    The Rhino-Rack Load Bars, 46 Inches # RRVA118B-2 with the Legs # RRRLKVA, and the Fit Kit # DK472 will work well to carry your kayaks on the roof of your 2008 Mini Cooper hatchback. At 96 pounds, your kayaks are within the weight capacity of the rack, however you will want to check your owner's manual to confirm the weight capacity of your Mini Cooper's roof. With the load bars being 46 inches long, you should not have any problem carrying the kayaks on their sides. The kayak carrier...

    Since the total weight of your kayaks is 139.2 lbs and your 2017 Chrysler Pacifica Limited is rated for 150 lbs then you can definitely transport all 4 on your roof! For your application I do recommend using the Rhino-Rack Nautic # RRS520 over the Thule Stacker # TH830 because it isn't as wide which will help with your crossbar space. You can use the Rhino-Rack Anchor Straps # RRRBAS-2 for attachment points at your hood and hatch and then the Rhino-Rack Cam-Buckle Cinch Strap and Anchor...

    We do not carry a part that adapts Rhino-Rack Nautic Stack Kayak Carrier part # RRS520 to fit the Yakima round bars. It fits the Yakima Whispbar (aero) and the Yakima Heavy Duty bars (square) but not the round. I recommend the Thule Stacker part # TH830 which will allow you to carry 4 kayaks on your Yakima round bars. It also comes with the tie-downs and folds flat when not in use. The kayaks cannot be longer than 10 feet to use the Stacker.

  • Carrying 3 Kayaks on a 2010 Volvo XC60 with Factory Roof Rack Made By Thule
    Three kayaks would be a tight fit on the 37 inch bars on your 2010 Volvo XC60 but I think you can do it. But you would just use the Thule Stacker # TH830 since it handles up to 4 kayaks. The kayaks fit on either side of the bars so there isn't a way that it could damage the kayaks. And the kayaks are not going to weigh enough for the crossbars to damage the kayaks. The only issue is that you need to check the roof rack and roof weight capacity in the owners manual and/or consult Volvo....

    You could possibly put three kayaks using J-style carriers on your 2010 Toyota Corolla roof rack but it would be a tight fit. I recommend using a different type of carrier such as the Stacker, # TH830. This will allow you to hold the kayaks up on their sides which means you are maximizing the useable space on the crossbars. It will also be lighter than using 3 J-style carriers. Weight is another important factor. You will need to check the vehicle owners manual or with Toyota to determine...

This carrier comes with everything needed to attach to your crossbars plus straps for securing a kayak to the carrier. If you are looking for a carrier that would be better suited for carrying 2 kayaks on the very short crossbars of your vehicle the part # TH830 would be a better choice.

Thule confirms that the Stacker is compatible with your factory roof rack. The Stacker includes bow/stern tie downs, and one set of straps to secure one kayak to the carrier, but you'd want an additional set of straps. I highly recommend the etrailer tie down kit # e36ZR.

    The Thule Stacker # TH830 is a great kayak carrier to carry the 3 kayaks you have but you will need a roof rack installed on both vehicles first. For that I'd recommend the Rhino Rack Vortex Rack # RRVA118B-2 and # RRSX100 for the 2015 Volvo XC70 and then the similar Rhino Rack # RRVA126B-2, # RRRLKVA, and # DK453 for the 2018 Honda Civic and you'd be set. There isn't a single rack you could go with that would fit both vehicles which is why you'd need a totally different rack for both vehicles.
