Is this right for you? Product Expert Kathleen M says:

Yes, if you:

  • Travel with a small fleet of boats -this allows you to haul up to 4 (if you get a couple extra straps)
  • Park your car in a garage and would rather just fold down the rack instead of taking it off every time
  • Have lots of gear to bring with you and need to free up space in your truck bed by mounting the kayaks to your roof or ladder rack

No, if you:

  • Need to transport kayaks longer than 10’
  • Have a boat that can easily get damaged from riding directly on the roof bars
  • Worry about the rack getting snatched if you leave it on your roof while you’re out paddling
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.

Thule Stacker Kayak Roof Rack w/ Tie-Downs - Post Style - Folding - Clamp On - TH830

Average Customer Rating:  4.7 out of 5 stars   (59 Customer Reviews)

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.


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.


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

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?
-- comment by: Sue C - 05/29/2015
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 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.


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.


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


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!


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.


Fast delivery perfect set up for my kayaks. Very happy with purchase


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.


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.


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.

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

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.


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.


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.


These TH830 hold the kayaks side up for less wind resistance. Easy to tie to but I do carry a step ladder to reach center on top of jeep


Great racks. Perfect for my kayaks.


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

Works great, no problems with this product.

Would have given 5 stars but one of the bow/stern ropes was frayed a bit in the middle of the rope. Came from the factory that way as the plastic bag it was in was completely in tact.
