Smooth transaction.i got what ive expected and im planning to order the rhino basket for my rack.thank you etrailer.

- DK399

Fits my Chevy Sonic very well. Good quality. The roof rack was worth every dime I paid. I bought it to put bikes on my roof, but I have used to carry a canoe, sheets of plywood and plywood.

Fit my 2016 Chevy sonic perfectly. Easy to install with a video etrailer had done for an earlier model sonic. It has a nice look and is very functional.

2013 Chevrolet Sonic

We put this rack on our 2013 Chevy Sonic Hatchback because it was the only model out there that would fit. It's been a year and no issues at all - no rusting, nothing coming loose, doesn't catch. We had someone experienced install it for us along with the bars and our cargo box and haven't had one issue. Definitely recommend this product - we got a great price too.

Outstanding! Was relatively easy to install, looks great. Very aerodynamic and sturdy. Unnoticeable fuel mileage difference. Highly recommend Rhino Rack product and etrailer.com. Product delivered promptly. Please keep up the good work and many thanks!

Review from a similar DK in Roof Rack

This review covers the Rhino Rack 2500 Vortex Aero crossbars and associated parts (DK284, RRRLKVA, RRVA137S-2) for a naked roof installation on a 2018 Honda CR-V. Very solid racks. We just took our first trip using them and the didn't budge. As recommended, a few days after installing, I tightened the bolts a bit. I'm not sure they needed it--just a little insurance. The installation process was clear, but fairly detailed. It would be easy to miss a step, so take your time. Also, I tried a couple shortcuts in the order when installing on the car, but had to back track. So, go in the order they give you. The racks easily supported our filled "pod" and a couple surfboards, strapped side-by-side. Sorry, no photos of the rack loaded. One thing to watch out for is that our old Thule pod almost didn't fit because of the thickness of the racks. I had to loosen the bolts almost entirely. Of note: I feel that although I followed the measurements to the millimeter, the fit on our 2018 Honda CR-V wasn't exact. Where the pads sit on the roof of the car didn't align perfectly. I could have adjusted this by just re-trimming the rubber pads that go in the channels, but it's not a big deal, so I just left it. Finally, I do have one concern. The angle of final installation doesn't really protect the racks from theft very well. The plastic plate that locks over the screw would allow someone with the proper tool to get up under it and loosen the bolts. That being said, someone so inclined could also just break the little plastic door or drill a hole in it to access the bolt. So, I guess it's just a deterrent anyway. Overall, I'm very happy with the racks and etrailer.com! Despite shipping delays due to Covid-19, they were able to get the racks to me in time for an upcoming trip. I did choose to expedite shipping, but the cost was very reasonable.

The racks are still working well, a year later. Ive used them to haul small loads of lumber and other items from the local big box hardware store.

Review from a similar DK in Roof Rack

carry my old town pdl 120 kayak on my 2014 Ram 3500 Crew cab dually. Heavy kayak. I'm a full time rider and sometimes travel hundreds of miles before stopping. Never had an issue. Front rack had a lot of wind noise but I wrapped paracord around it...problem solved. Worth the money!

Still going strong. Just make sure you tighten periodically.

Review from a similar DK in Roof Rack

I've had Thule & Yakima products over the years, with no issues. But I'm really glad I ordered this set-up for my 2021 F-150. I think you get just as good of a product from Rhino, maybe even better, for a slightly lower price. Everything feels sturdy and well made (with the possible exception of the locking covers, which feel a bit flimsy). I really like this set-up, and the precise measurements and guides made for a perfect snug fit. The rubber strip running on the upper long edge of the bars feels like it will definately help keep accessories from sliding out of place.

Review from a similar DK in Roof Rack

I am a female age 61. I has to call pretty much every step of the instructions but I was able to install myself however the measurement for the width using the measure sticks was not quite accurate foe the rear rail. Customer service was very good at assisting me until the last call they never emailed me so I could send photos. I’m only going to be transporting a inflatable paddleboard so the discrepancy shouldn’t matter much. I’ll figure it out later cia customer service next year when I put back on.

Review from a similar DK in Roof Rack

Great product, very well built, heavy duty. the assembly and settings instructions are easy to follow and when I placed it on the roof of my 2015 f150 super cab, it fit perfectly with no further adjustments necessary. I am very impressed with this Rhino Rack and feel it will probably outlast me and be handed down through many generations. Also purchasing from etrailer was an awesome experience, fast free shipping. easy website to navigate.

Review from a similar DK in Roof Rack

The roof rack is great. But the DK432 instruction doesn't fit my Ford Edge 2019 very well. The measurement strip length for front crossbar is about 160mm instead of 150mm, the measurement strip length for rear crossbar is about 150mm instead of 140mm.

Thank you for your review. The strip size will vary with each year, make, and model.

Review from a similar DK in Roof Rack

I ordered the Rhino-Rack 2500 Series Roof Rack for my Subaru Legacy. It was so easy because all the related parts needed for install all came up together so I didn't have to hunt around for them. I wasn't sure I could install this myself. It seemed daunting at first but as I moved through the instructions I was able to do it! The rack fits well and is solid and sturdy. I highly recommend Rhino-Rack!

Review from a similar DK in Roof Rack

The Rhino crossbars were shipped and received within 3 days of my purchase. Very fast and efficient! Great and solid quality. I was notified immediately when it was shipped and able to get tracking updates. I would highly recommend this company and their products. I haven’t had a chance to get my kayaks on the crossbars yet, but I know there won’t be any issues with their strength and durability. Thanks for your great service and product guys!

Review from a similar DK in Roof Rack

So my rating is primarily based on the product. However etrailer was very helpful in getting me the right products and getting it to me quickly! The product itself is a very good. It was quite easy to install and holds up quite well. The instructions however were a bit complicated, the instructions in the box with the clips gives you specs on various products and measurements. The box with the brackets gives you the run down on the installation. I attempted to follow it word for work but found the measurements didn't seem to match up. I eventually winged it and did measurements of my own, making sure everything was even and squared up, this is why I rated it a 4 out of 5. Beyond that I like the product. It's quite sturdy, went together quite easily. I've yanked on it in every direction I can even after I applied the basket. I do manage to get some wind noise but I believe it's primarily from the basket. Overall I'd definitely recommend this product

Excellent roof rack for my naked roof ...plus the installation video was perfect - rather than read thru the instruction manual the video saved the day. Customer service here was perfect too - my shipping had been delayed - and not once but twice the folks here helped me get it expedited very happy with product with video and customer service

The fit of the Rhino roof racks is perfect! Installation was straightforward and not difficult. The kayak J racks were added and not part of the Rhino roof racks.

Review from a similar DK in Roof Rack

I ordered the Rhino Rack for my 2017 Mazda 3 hatchback. The first thing I was concerned about was if the rack would interfere with opening my moon roof but that's not an issue. However, the rack does whistle pretty loud with the moon roof open at high speeds but that would happen with any roof rack. For my car, the fixed mounting points on the roof are not accessible with the normal molding strips on the roof. So I had to order new Mazda molding strips with openings that provide access to the roof mounting points. You'll have to research which ones to get for your car. But, luckily, they're not expensive and are easy to install. Ok, now for the Rhino Rack. I'm fairly handy and have installed roof racks before and the whole install took me about 2 hours. But it wasn't totally straightforward. The directions included in the box were for clamping a rack to the door openings and not for screwing the rack mounts into the fixed points on the roof. So they were not very helpful for my car. In addition, the towers were set up for the clamping arms, so I had to knock that hardware out of the tower arms and install the hardware for screwing down on the roof mounting points. Also missing from the instructions were the spacing measurements for the roof rack. So I had to go to Rhino Rack's web site and search for the spec sheet for my car to find the measurements. The good news is that those measurements were dead on when I went to screw the rack onto the roof. What really saved me was watching the etrailer install video for the Mazda 3 (that video was for an older Mazda 3 but the instructions worked fine for my 2017). That will show you how to do it. Once installed, the rack was sturdy and looked great. I've since installed two Rocky Mounts bike carriers and they are awesome. Although, the forward tilt of the front cross bar (fault of the car's design not the rack) made the install a little tricky and I had to tighten down the bike rack clamp unevenly back-to-front to get it to work. Just thought I would mention for anyone planning on carrying bikes.

Installed by myself (first time ever installing a roof rack) and it was super easy. Found video on YouTube from eTrailer showing how step by step). Impressed by the quality of the kit. Fits perfectly on my 2020 Honda Fit.

Review from a similar DK in Roof Rack

The boxes were delivered quickly and promptly (earlier than expected). The instructions were easy to follow. I just needed the space to lay everything out and to match the numbers to the correct items. My only issue was that the specs for my 2016 Nissan Versa Note SV asked for 144mm for the front, but in fact, it needed to be 148mm. The rear asked for 142mm, but it needed to be 144.5mm. Once I figured that out, the rest was straight forward. The crossbars are super sturdy and the rubberized top is a nice add to keep things from slipping. Thank you! I plan on installing a V-boat rack on the car rack. I can't wait to transport canoes!

Its been a year and Ive been transporting multiple canoes on top of my car. It has been great! The biggest risk with the boats on a small car is when its windy that it would rock the car and the crossbars. The crossbars have movedslipped a little bit, but its still super sturdy. Great product.

  • Recommended Roof Rack and Kayak Carrier for 2014 Chevy Sonic Hatchback with Sunroof
    Installing a roof rack on your 2014 Chevy Sonic Hatchback that features a powered sunroof is not an issue. The potential problem is only if you want to operate the sunroof with the crossbars mounted on the roof, as it's possible that it may interfere with the bars when being raised or with any accessories you have mounted like your kayaks. Generally speaking though, we don't recommend opening the sunroof with a roof rack installed anyway, as the crossbars (even the quieter aero-style units)...

  • Roof Rack Recommendation for 2012 Chevy Sonic
    The track mounted roof racks all use the same dimensions for the channels. They all use a 3/4 inch by 3/4 inch channel and we have found that the feet kits of the racks all fit in the same channels. That being said, the roof of your vehicle has a curve to it and mounting tracks to it would not be an ideal solution. Plus it will permanently modify the roof. The track setups really should only be used on flat surfaces like pop up campers and truck bed camper shells. The best solution will...
