I got the roof rack mounted anyways. Better pics to come when it's all finished!



After a year, I don’t always have them on the car but they are still holding up great! Got easy to put on and off FAST!

Nissan Versa

This rack works perfectly on my Nissan Versa for carrying my two Perception Sound 9'6" kayaks. The Rhino-Racks look good to me. The kayaks can rest directly on the rubber pads on the rails, unlike the Yakama racks I had in the past that had bare pipe rails. Also, I expect I can buy parts to adapt this product to a different car without having to buy new towers. I am sorry there are not hooks or loops to attach bungees when carrying lumber. They are noisy in the wind, but less so when carrying the kayaks.


Thanks to etrailer, I am ready to do some serious summer exploring with my 2013 Mazda 3! Rhino Racks, Malone top box, and Kuat bike rack!


love it, no problem and easy to install and take on and off, 47,000 miles on the highway and not a single issue. I even like the song the ladder hums to me driving down the interstate. This is my second Rhino and both have preformed to a high standard.


Things went well. Customer service was great.


Fast service and was everything I expec ted


Found Package was broken after delivered, and missing 2 end cap

2012 Suzuki Grand Vitara

These are as advertised. Once the leg kit is in place, super simple to install. Great finish, I believe will give great service. The only test to be determined is if they "Howl" in the wind. If so, I believe a second set of rubber fillers, installed in the underside will solve the problem. Another modification expense. Thanx.

Liked that the website does all the thinking for me. Too busy.

Nice rack system, strong and durable. Used on a Ford e350 to mount solar panels. Only draw back, one of the L brackets that goes under the rain gutter was not bent square enough and this caused the bracket to slide off when tightened. I had to adjust this with a clamp and hammer, no issues since.


I’ve had this rhino rack for over 3 years and it’s been excellent on long road trips to the ski slopes. A year after my purchase, I realized that I was missing the plastic coverings that attached to the end of the bars and called their customer service to resolve the missing pieces. I was impressed with their quick response and seamless delivery.


For the most part easy install, very straightforward, inserting the rubber into the rails needed some effort. The video on your website of the install has the rubber already inserted.


The M8 bolts and spring washer were missing from the packaging. A 30min job turned into 3 hours. At this price that is very disappointing. The racks are solid but installation is a bit weird. I wish the M10 channel nut was in a fixed position. It was a pain getting it to stay in the proper orientation while tightening. Also the end caps don't snap in and are easily pulled off. Overall the racks will do good but for the price I was expecting better.


Amazing product. Fit, finish, quality is absolutely amazing!
Have hauled our bikes all over MI, through the UP, and back. They never moved. Rack is super simple to remove from the rails to grant full access to the PU bed.
I think this is one of the Best options out there for taking your bikes with you while still having your covered bed space. I also can install a Ski box for the winter. Ski's in the box while gear in the covered bed.


Kit was great, except my SnugTop cover
required longer T-Bolts for mounting the tracks. The 1.5 inch ones provided were too short. It was a little tough sourcing T/Bolts that would work. It would have been nice if longer T-Bolts could have been an option from Rhino Rack.


These are the perfect racks for a low profile mounting of solar panels on my Sprinter van.


I am normally a exclusive Amazon shopper, but etrailer gives equal or better service and has specialty items you just can't find anywhere else. The pricing is great also. This is my 4th order from them on this project and the response has been perfect and the shipping has been prompt. They even offered to take back an item that I did not need. I desperately wanted to mount my 19ft Kayak on my new RV and with some Rhino RT tracks, a Rhino Nautic kayak lifter, a few really heavy duty rivets, and some ingenuity, I was able to accomplish the task. I am replacing the current Nautic bars with the heavy duty bars. See the attached pictures.

  • Roof Weight Capacity of 2005 Toyota Highlander Fitted with Rhino-Rack Heavy Duty Roof Rack
    The Rhino-Rack Heavy Duty Roof Rack for your 2005 Toyota Highlander, which consists of parts # RB1250B-2 and # CXB, does carry a 200-lb weight rating. Your vehicle itself will also have a roof weight capacity that could be more, the same or less. Your manual's indicated weight limit of 100-lbs could be for an OEM roof rack, or it could be for the overall roof structure itself. If Toyota says the roof itself can handle 100-lbs and no more, then you will have to abide by that lower rating....

  • Does Rhino Rack HD Roof Rack Fit 2011 BMW X3 with Naked Roof and Sunroof
    The Rhino Rack HD part numbers # RB1250B-2, # RRRLKHD, and # DK295 is a confirmed fit for your 2011 BMW X3 with a naked roof and would not interfere with the sunroof. You aren't going to want to open the sunroof with this rack installed though as it will make quite a bit of noise. If you keep the roof clean as well as the mounting pads of the feet there would not be any long term damage done to the vehicle.

  • Does Rhino-Rack HD Roof Rack for 2020 Toyota Corolla Sedan Have Static Load Rating
    I checked with Rhino-Rack and they specifically mention they only have dynamic (moving) load ratings, and that is exactly what the 165 lb capacity is with the rack that fits your 2020 Toyota Corolla sedan. Rooftop tents generally only call for a rack to have a certain dynamic capacity so I recommend checking out your tent's manual to find out. As for the roof rack for your 2020 Toyota Corolla, here are the parts you need: - Rhino-Rack Heavy-Duty Roof Rack Crossbars # # RB1250B-2 (Black)...

If your roof rack has the Rhino-Rack Heavy-Duty Roof Rack Crossbars Black - 50" Long - Qty 2, part # RB1250B-2, you will need to add the aforementioned Vortex Aero Crossbars to the SX Series Legs to complete your roof rack.

  • Roof Rack Recommendation for a 2007 Chevy Trailblazer for Carrying Ladders
    I would recommend going with the Rhino Rack HD crossbar roof rack as it will have plenty of strength for your ladders. You would need the part numbers # RB1250B-2, # RLTP-2, and # RRVA-FK2-2 which have been confirmed as a fit for your 2007 Chevy Trailblazer raised side rails.. For load stops for the ladders you would then want the part # RRRLH. For 10 foot cinch straps you could also use the part # RTD3. Be sure not to exceed the roof weight capacity of your vehicle.

  • Roof Rack to Carry Ladders on a 2001 Ford Escape
    Your 2001 Ford Escape could have 1 of 3 possible roof configurations. I will provide recommendations for each type. Since you are using the rack to carry ladders it doesn't have to be a fancy rack so I will provide good economical options. First, if your Escape does not have any rails or bars at all on the roof the most quality option is going to be a Rhino-Rack using the following parts: Vortex Crossbars # RRVA126B-2 Feet # RRRLKVA Fit kit # DK099 If your Escape has factory tracks,...

  • Will Yakima SkyBox 21 Fit on Rhino-Rack Heavy-Duty Roof Rack Crossbars
    The max dimensions for a crossbar that the Yakima SkyBox 21 # Y07337 can accommodate is 3-1/2" x 1-11/16". The Rhino-Rack Heavy-Duty Roof Rack Crossbars # RB1250B-2 are a little too tall for that so if you want to stick with Rhino-Rack you need the Vortex crossbars like part # RRVA137B-2. If you let me know the year/make/model of your vehicle I can make a roof rack recommendation for you. The Rhino-Rack HD bars are much taller than typical crossbars so none of the Yakima boxes will work,...

So the lowest of the two numbers is what you go with in regards to towing capacity. So please check the towing capacity...
