Most Popular Clamp On for 2010 GMC Sierra

I installed these as soon as I got them and I’ve got to say, there are some extra holes for screws that are a tad misleading and the pieces that secure it to the cross bars don’t seem super secure. For reference, I do have Rhino Rack’s vortex crossbars so this should fit snug. The rubber tops were tough to get into place and I am worried they’ll snap when I go to remove my rack but Rhino Rack has yet to fail me with their products so I bet it’ll work out great!

This is a great product. As a novice kayaker I was nervous. The assembly was easy with clear instructions. My sales professional Crystal K. was a pleasure to work with. She knew the answers to all my questions. From placing the order to the delivery I am very satisfied. I will be using etrailer again. I can't wait to get my kayaks to the water.

Love the roof rack! Works great for kayaks! They fold down when not in use..perfect!

First experience with purchasing from etrailer. Absolutely felt that my order was personalized which is a nice touch. The Rhino Rack S512 folding JStyle Kayak holders arrived boxed impeccably with no damage whatsoever and the price was great! Fantastic first time experience. Looking forward to using them. Thank you.

Bought a pair of these to go on 59" rhino rack bars on our Outback Wilderness and am really pleased. I left the bars full width - they are not a head banger on the car - and mounted the Hullavators as far outboard as possible which means the kayaks clear the side of the car and wing mirrors without folding them in. I did have to modify one Hullavator to make the Hobie Lynx fit (36" wide Lynx = 36" max Hullavator width)

The Hullivator was for my wife to give her the option of loading and unloading by herself. It couldn’t be better. She now goes kayaking anytime she wants with little effort and no need for me to help her. Excellent product that’s worth every cent. Was super easy to install too.

Excellent product, easy install, secure on the crossbars, a bit lower ride height and a simple rolling mechanism. A significant improvement over my older Yakima Handroll racks.

The Sweet Roll will not support my Old Town Topwater 10.6. The brackets spread out on the crossbar under the weight. This year I will try a Yakima Big Catch. The Sweet Roll works fine with our Old Town Loons.

Love the product. Can't wait to take our new tandem kayak out. etrailer is fast, efficient and has great prices. I'm also a fan of their efforts to provide good customer service by seeking customer feedback.

I bought the Rino-Rack , RR571, to replace an old set of Yakima saddles that I gave to my daughter along with my kayak, Yakima bars and towers. I have just recently purchased another kayak and didn’t want to spend the money again for the Yakima saddles so selected the ones from Rino-Rack. They look to be a pretty good product, not as good as the Yakimas but plenty good enough for me. After installing them and loading and unloading several times I find the saddles tend to turn on the round bars even though I have them tightened down as hard as I dare. I ended up boring a small hole through the base into the pipe of the round bars and inserting a half inch No. 8 sheet metal screw. Time will tell if that keeps them from turning. If not I’ll have to try something else. The included straps are first rate and I think the saddles themselves will be fine it’s just the clamping system that I question. They would be fine for any flat, square or oval bars but round bars but round bars are hard to clamp to even though the advertisement states they work on round bars.

I have (2) Wilderness Systems Pungo 120 kayaks and was looking for something better that the cheap J-Shape kayak holders that I purchased elsewhere. Unless you are tall enough to lift the kayaks and install them from the side, the loading of a kayak on it's side is unwieldy and somewhat frustrating to keep the kayak from flipping to a horizontal position. I am using the factory racks with crossbars on my 2006 Toyota Highlander. I was looking for a solution that would allow me to load 2 kayaks with the keel down. Using a large bath mat to protect the paint I was able to load the kayak by myself and I am 5'6". The one thing that they could improve is that the rubber pads on the wings are very tacky. Once that you set the kayak onto the wings, the kayak will not move back and forth. You will find it very hard to move the kayak front to back once it is set in the cradle. This is a good thing since the kayak could slide off should a strap fail. The Pungo 120 has multiple angles so the contact with the wings are very minimal. The rubber does keep it in place before strapping them down. Once you load the kayak onto the wings, it will stay where it is.. it is a kind of a struggle to move the kayak.. a solution is to throw large beach towel on the wings before loading your kayak and you can position the kayak with ease. Once you have centered your kayak, lift the kayak one end at a time and remove the towel. Bow and stern tie downs are necessary to completely secure your kayak. The wings are 28" across and will rise 6" above your crossbars that you attache them to.

Bought two sets for two boats. Installed on a 2020 Forester and will be able to carry two boats side by side. Sturdy racks and easy to assemble and install and will be easy to remove when not in use. They will also fit on truck racks so the ease of install/removal will be a real plus. Side by side mount on this vehicle required placing the racks a little more outboard than I like but should not cause any problems. I will strap the boats to the crossbars as suggested in the instructions for additional stability. PS. one set was returned merch. Got a better price and can't tell that it was ever out of the box. Yay me.

Great product for my kayaks. Great experience with etrailer as usual. I recently restored a trailer and converted it for kayaks. Purchased all hubs, bearings, races, lights, etc from etrailer. It's the go to place for trailer products.

Best solution i could find for a 95# 12’ fishing kayak for a F150 with a roof rack (i have a thule removable). It performs really well. Only complaint would be rubber coating on brackets that go under the truck rack rail cracked so i worry ot may come off with age. I still recommend this. I pull a travel trailer so I couldn’t use a bed extender & the roof was my best solution.

Arrived quickly and was very easy to assemble and attach to the roof of my Jeep. Now that I have the initial setup complete with the proper placement of the entire system, attaching and removing the kayaks will be a breeze. Will definitely make hauling our kayaks much easier and safer.

I think the Thule Hulaport kayak racks are the best, most secure way to transport your kayaks. I had these on my Xterra and hauled two kayaks up to Cape Bretton park in Nova Scotia, Canada from Connecticut, USA no problem. We were even able to store gear in the kayaks for the trip. I’m so excited to have them for my Crosstrek. Highly recommend these!

've previously used the Yakima Kayak Stacker (old style), which worked fine but I always worried the straps would slip off the hook at the top while I was loading boats. They also didn't fold down, so had to be removed after use unless you wanted to look odd and cause a whistle while you drove down the road. They didn't have a universal attachment option, requiring adapters depending on the style and make of your crossbars. More recently I got the Thule "The Stacker", which is a superior solution. You thread the strap through a closed loop at the top, so you don't worry about straps slipping off while you're loading boats. They fold down after use and have a universal style attachment that fits around most styles and makes of crossbars. Good stuff. I really like the straps that come with these, as there is a rubber cover that slips over the metal cam buckle to protect your car's paint while you're tossing the strap over your boats to strap everything in. In order to shuttle our boats for river trips, we needed stackers to fit on both our cars, so it was time for another set. I had never heard of Rhino Rack before, but the lower price than Thile caught my eye, so I read about them and decided to give them a try. The Rhino Rack Nautical Stack used a closed loop at the top, which I liked better than the Yakima or Malone options, and came with the hardware necessary to install them into the C-channel of my Malone aero crossbars, which I wanted to try. I remember that with the Malone stacker, you had to buy the C-channel mount hardware separately. I really like the Rhino Rack Nautical Stack. They are a single post design, unlike the loop style of the Thule "The Stacker". I don't know if this cuts down on vortex drag, but it definitely saves you a couple horizontal inches up where the boats stack. The Rhino Rack Nautical Stack has textured rubber strips on either side of the post, which I believe is intended to cut down on vortex drag, but is also quite helpful in that boats tend to slip much less when you're just leaning them up against the post as you load up before you strap them. That's smart. The Rhino Rack Nautical Stack feels really solid. The mechanism for folding them down and locking them upright is easy to use and feels solid. Installation instructions were good. I tried to install into the C-channels without removing the rubber tubing in my Malone aero crossbars, but couldn't get the little squares to slide into the slots with the rubber tubing in place, so had to cut the tubing, slide the Nautical Stacks into place, then cut down some of the tubing I had removed and replace it in the remaining unfilled crossbar slot. That's not a knock on the Nautical Stack; just a tip in case you're trying to do the same kind of install I did. The one area in which I was less impressed was the tie-down straps that come with this kit. The metal cam buckles have no covering at all, so I'll probably still use my old Yakima and Thule straps instead and use these as backups. But overall, I think these are going to work at least as well, if not better, than the Thule option, and for quite a bit less money.

So much better than the 'C-shape' kayak holders. These things allow you to fit inside a garage, and add up to four kayaks. Very easy to use.

This kayak carrier works great with my factory Rav4 roof rack and 10' Tamarack Angler kayak. I did break one tightener knob but probably over-tightened it. And it was replaced for free. I can load and unload the kayak easily and it doesn't budge going down the freeway. I can even drive in and out of the garage with the kayak on the rack for easy storage hanging from the rafters.

Installed this Thule Top Deck Rooftop Kayak Carrier System with tie onto our Thule Roof rack system. Easy to install and this will carry our handmade 17' Wooden Sea Kayak. Very well made.

The product seems great but I have not figured out how to get it safely attached to my bars. I have an Agricover Adarac on the bed of my truck and the crossbars are 1-1/2 x 1-1/2 inches square. I thought this would work well since it's for up to 3-1/2 x 1-11/16" crossbars, but it isn't secure on these. I'm going to try and figure out an alternate method for attachment though. Thule Hull-a-port Pro's are the perfect (mounting) solution but don't seem to be made any longer.

Great product and great customer service! Very easy to install, but I highly recommend to watch the installation video first. We used typical black office clips to clip the excess straps down since they came untangled when driving. Also, I recommend to purchase locks for the racks since we are concerned someone may steal them because they are so easy to take on and off.

These work great and I was able to install them on the OEM rack for my truck. The only downside is that the threads for the clamp hang down a little too close to the roof for comfort.

The Rhino-Rack 2 Kayak Carrier I ordered from etrailer was easily reviewed and ordered from their website and ALL communication relative to order confirmation and extreme detail included in their tracking was nothing short of phenomenal! The items were packaged with care and arrived intact. These fit our basic Lexus crossbars and is the perfect product for carrying our two (2) kayaks. My hat goes off to the great folks at etrailer -- It doesn't get any better than this!!!

The keys are an issue (wish they were metal), but everything else is great! I go sunrise kayaking only and hate putting straps on with cold hands at 3:30 in the morning. I have a Nissan Pathfinder and was able to put this on with another set of Malone J-hooks so that I can have a second kayak when I go with someone. Once the fear subsides of it possibly falling off, you realize how quick and easy this thing is to use. It takes me 1 minute instead of 9-18 minutes to get my kayak up and secure. I have tested it at 75mph without any jiggling or issues. I sat on this in my shopping cart forever and finally pulled the trigger. If you kayak at least 10 times a year or are going at high speeds for extended periods of time in warm weather, totally worth it. If not, well, there are cheaper options out there.

Rec'd earlier this week, so today i will install. The item was obviously a return. The logos are nearly scratched off in places, all the items were loosely thrown in the box, and the 10mm wrench and hex key were missing. i think everything else is there. The keys should be a bright color instead of black, some spray paint will fix that. Anyhoo, i am a little disappointed.

Brought home a new kayak yesterday using this J cradle for the first time. Easy to set up and load. Two complaints: not impressed with the strap buckles - had to tie knots to secure. And the 3-inch bolts weren’t long enough to easily attach the cradle to my Rhino Rack crossbars, so I had to replace them. Also got my finger pinched pretty good adjusting the cradle knobs - my fault for not being more careful, but just saying …

Great product for the price - The cradles were very easy to mount (and lay flat once folded). The videos were helpful in showing how to set the straps in the most efficient way. I test-drove my car today with my fishing kayak on top on a 80-mile round trip (a mix of freeway, country road and dirt tracks). The kayak was perfectly still, no particular wind noise and I was able to muscle to kayak up the roof and take it down on my own (it's a 52 lbs boat). I really recommend that product and I'm glad I went for J-Style cradles!

Wry disappointed in such an expensive rack and kayak carrier. It is extremely difficult to reach the carrier to place two kayaks. We are very uncomfortable transporting the kayaks for longer and highway travel. I would not recommend these to others. We likely will purchase something other in the future. I’d rather put the kayak in a car or pickup truck that they would fit in.

We bought this Kayak rack for my mom to put on her 2016 Jeep Grand Cherokee so her and my dad could haul their kayaks easier. The mounting hardware was a little tricky at first but once we figured it out, it wasn't bad at all. It holds the kayaks in place nicely. Had no issues with them getting loose or moving around. Seems to be built well and they're very happy with it so far.

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.

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.

I use these 2-3 time weekly for my SUP I fish off my SUP and this rack is a great investment for quickness and ease of strapping. Thing I like best about etrailer is how fast I get my stuff.

After doing some research decided to go with the Yakima roof rack setup for our VW Atlas. Love the look and functionality of it all. Got the SUPDawg paddle board carrier to go with it. Love the locking capability for piece of mind when leaving boards unattended. We are VERY happy with our choice. Drove on highway with two paddle boards and it all went smoothly with zero wind noise whatsoever. Definitely worth every penny. Will recommend.

I had the moulded downloader and needed the folding in order to fit in the garage. The top feed for the tie straps isn't as good as the moulded J-style rack, the strap came out of one, but the kayak stayed where it needed to be. It is easy to raise and lower the rack, but I am not always sure at what angle I am supposed to set them. With the moulded J-style, they are at the perfect angle for holding a kayak. I wish the clamp that goes under the bars were a better fit for the oval bars, but they do send two different size bolts and the longer ones work.

The Malone DownLoader is very good value for the money. The J-style cradle is nice when you have to muscle a kayak on top of a tall crossover or SUV. You can hook the edge of the cockpit onto the base of the cradle and flip the kayak up onto the metal hoop support. Carrier installation and removal is easy and doesn't require any tools. Materials are good, but not great and that's what prevents this product from getting 5 stars IMO. The foam padding is nice enough and has been durable, but the metal plate that attaches the carrier to the roof rails is plastic coated steel and the plastic cracks over time, and leads to rust on the steel plate beneath. Not a big deal, but it might compromise the plate over time. I also wish that the provided nylon straps were longer, and that the ratchet buckles were covered in rubber to protect the roof of the vehicle and the windshield when you're trying to get them around the hull of the boat. We quickly replaced these with longer aftermarket straps that have rubber covers over the buckles. Those minor points aside, the Malone DownLoader kayak carrier gets the job done easily and safely, and does so at a very affordable price point.

I need replacements when a pair of Dockgrips was was lost or stolen. When others were stocked out, etrailer came through. Fast shipping and courteous service!

The Thule DockGlide Kayak Carrier and the Tie-Downs that came with it are a very functional High Quality Product. Once the DockGlide Carrier was properly positioned on the Cross bars it attached easily and solidly with the associated hardware. The Kayak slides on and off the Carrier very easily and is quite secure once properly tied down. I enjoy Kayaking and the DockGlide Kayak Carrier enables me to get where I want to go.
