I bought Rhino-Rack Heavy Duty Crossbars because they are made to support Rhino-Rack products, including the Batwing Awning I had purchased for a RAM Promaster High Roof van. The crossbars work very well with the awning. However, I have discovered that Rhino-Rack does not provide a solution to attach non-Rhino-Rack products directly to the crossbars. For example, solar panels. There are fixed attachment points for racks on a Promaster. The distance between the crossbars is greater than the length of my solar panels. So I need to attach side rails to my crossbars for mounting my solar panels. Rhino-Rack does not offer side rails that can be attached to the crossbars. They only make baskets and brackets for specific items. They recommend going to licensed installers to get side rails installed. But I could not find an installer who is willing to help. They don't want the hassle and/or they don't want to jeopardize their standing with Rhino-Rack. So, I am left with having to come up with a solution on my own. Very frustrating.

eTrailer is always very helpful and tried their best to find a solution for me. But they were stymied, too.

If you just need Rhino-Rack Crossbars for other Rhino-Rack products, they are great. If you want to carry other manufacturer's products, look for something else.

Work great and look good. Easy to insta ll.



by:

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.



by:

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



by:

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.



by:

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.



by:

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!



by:

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.



by:

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.



by:


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.



by:

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



by:

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.

Great product
I installed them on my
2020 GMC Sierra crew cab on the bed rails to use as a Conor rack, kayak rack bed tent .

Works great !

Really has come in handy as I installed this over my truck bed on top of a retractable bed cover that came with T -tracks. I can load the truck bed with smaller items and use the roof racks to hold a Thule box or just strap on heavy and larger items. Great product.

Great design, heavy duty while not bulky

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.



by:

Worked as intended on top of my Ram Promaster and was super easy to set up.



by:

This works great. Very strong and reliable. Holds my ladders with ease. I’ve had it loaded down and done 80mph on the highway no problem.



by:

Ok… giving this item four stars as an overall view. The good: it fits a Jeep Wrangler perfectly. With the appropriate legs, it canvases across the entire roof of the Jeep with the legs attaching to the gutters. The bad: just a bit too noisy for my liking, even with the appropriate wind faring (I don’t expect absolute silence since I have a one touch sky top). The noise is not a big deal on short trips, but it was definitely driving my wife and kids nuts on a 2+ hour drive (stick some headphones on the kids, problem fixed)

In the future, I might switch it up from these square rails and go with something a bit more aerodynamic…



by:

We have been very happy with our Rhino Rack system atop our 2018 Chevy Express Van. We carry 2 Kayaks ( sit in style, 14 ft and 12 ft) upside down on the van roof and use some eye bolts and ladder supports with ratchet straps to hold them in place.
It took a while to get them( due to being out of stock) but eTrailer has excellent customer service and kept in touch with us on the order status until they arrived.



by:

I just received my Rhino roof rack and am very pleased with the super fast shipping. The rack seems very strong and it’s very easy to install. I will have to order the 3rd rail also as I had planned on adding a rooftop tent and the tent wouldn’t have enough support on the back. ETrailer is a great place to purchase from since they have everything to fit your needs and service has been great so far. Will be ordering the 3rd rail now. Thank you!



by:

I purchased this because I needed 11" brackets and I only needed two to add to my existing setup. Other manufacturers (I could only find one) only sold packs of four at a ridiculously high price. My Rhino Rack mounts and bar arrived within a few days of my order and appear very sturdy and well made. I bought them to add a third support for an awning and a solar shower on the roof of my van. I think I found the perfect solution.



by:

Tricky to rivet tracks onto car with a manual riveter but once done, a great solution for the car with ease of bar removal. My only regret was going with the square bars which result in notable increase in wind noise.

  • 3 Bar Roof Rack Options For Roof Top Tent On A 2016 Ford Transit T350
    I recommend getting the Rhino-Rack Heavy-Duty Roof Rack Crossbars # RB1800S-3 over the Vortex Aero Bars # RRVA180B-3 because of the weight capacity. The Heavy Dusty Crossbars come in two colors, silver and black # RB1800B-3 and are 71 inches long with a weight capacity of 220 lbs apposed to the Vortex bars which only have 165. Both systems use the Rhino-Rack RLTP Legs # RRRLTPFC-3. This will give you the option to either mount your tent via T-Track or the tent can simply wrap around the...
