Always great products by RhinoRack and excellent service from eTrailer….!

Excellent product, very well engineered. ETrailer is great with shipping time and communication as always. The instructions aren't perfect and its much easier for me to follow a video. Both RhinoRack and another site have great install videos. Took me a couple hours just taking my time and being careful. I had to loosen the hard top to access the front spacer install but otherwise its very simple just follow the directions carefully when drilling thru your hard top. Measure twice cut once mindset.
The only negative was my package had been ripped open some and one of the parts had protruded and gotten scuffed up a bit. The powdercoating is pretty durable because it cleaned up well and is not noticeable really where installed. The price is also iffy. Its very well engineered and works really well, but for what it is from a material input cost... seems about 20% to high.

The only issue I’ve had after a year of use is the threads getting dirty in between trips with a RTT on. Maybe include some plastic fill plugs? I didn’t want to leave bolts threaded in for fear of seizing or dissimilar metal corrosion. Also, for the price legs should come with.

by: MP 09/29/2026

I think the purchase went through smoothly, the parts arrived quickly. And they were the only ones who had it close by. Thanks Etrailer & Naomi for your help

by: Josh 03/26/2024 One Year Later

It’s a good product. The only install issue I ran into is the drill bit I used (dewalt) for the front two holes on the hard top wasn’t long enough to work with the included drill stop and I ended up scratching the paint on the roll bars. I installed mine over the top of a carpet headliner with dynamat underneath. I did a “soft install” of the roof rack (used regular nuts instead of nylock, low torque, and no sealant), removed it, then put in the mat and headliner, then finished the roof rack install. Multiple cross country trips with my pioneer platform and no issues with excessive noise and no water leaks.

Platform racks are the best in the market I think. I'm removing my Platform rack from my 2007 Jeep Sahara JKU and installing it to my 2021 Rubicon JLU. That shows my love and devotion for this very durable and such a beauty to look at system. Had this rack on close to 5 years and still looks amazing. I'm not installing this rack anytime soon. Just wanted to make sure I have the Backbone system for my new JLU when the time comes. Pic of my red JKU with rack attached. Hopefully I can update with my black JLU pics later.

Best price on the part. Fast shipping. The install video made it a breeze. Rhino rack was a little lazy with the written directions and stamping all the parts. The etrailer video for 2015 JKU was needed.

Excellent product. Be aware that you WILL have to cut into the gutter guard to install this. I used a Dremel with a grind wheel to cut a roughly 2" x 1.75" square to reveal the second bolt insert hole in the center mount.

Best backbone I could find for a custom build. Flat lower profile more practical for my needs. Thanks guys!

Delivered fast and it fits well. Took me 1.5 hrs to install but could be less.

Hi Noel, thanks for including a photo with you feed back. The install looks great!

by: Scott 03/05/2025 One Year Later

It is a good starting point to improve on the stock FJ rack. I have had several different setups mounted to the Backbone, but eventually found a used Pioneer Platform that works best. The whole system from Rhino Racks is overpriced for what it is.

by: Scott 07/02/2025 One Year Later

I find it cumbersome to work with for what I needed using various carriers. It looked like a versatile setup, but in practice, for my needs, it falls short.

by: BobbyG 09/20/2023

Nice and sturdy but was a PIA to install… prepare to give yourself a few hours to button this up securely on your roof.

Great quality and was easy to install as the directions were simple to follow.

The backbone rails look great! However, the instructions need to be revised to include information that is Armada specific. Instructions for removal of factory rack is not included and not available anywhere I could find on the internet. It’s almost impossible to remove the end caps on the factory rack without destroying the tabs that hold them in place. Also, the middle connection point of the backbone has 2 bolts, the factory rack only has one. However, the second hole is there but you must remove the trim piece that sits below the factory rack. It’s simple to remove and reinstall without damaging the clips. In order to make the backbone rails fit, you have to cut an additional couple of inches from the existing window in the trim piece in order to expose the second hole underneath. This is pretty simple with the right saw but some additional instructions on this would be helpful. Overall, this is a great product, just need to make customers aware of the extra steps needed on the Armada vs the installation on the Nissan Patrol.

I have used the Rhino Rack backbone system on a previous Jeep and it worked well. Installation instructions were clear. Definitely recommend.
Also a word about etrailer. I have ordered a few times from etrailer. These folks have great prices and have really fast shipping. They are quick to respond to questions and have great follow up after the sale (5 star).

by: Troy 05/11/2021

Great product... I think the best roof rack option for a Jeep Wrangler.
It took me about three hours to install, by myself. Not a hard install. Just follow the instructions and, the etrailer installation video was very helpful also.

It’s the bomb. Great design. Well made.

It’s still rock solid with no rust.

@Spencer No rust after 2 years just shows that great quality! Stoked to hear its still rocking for you. I am curious as to what are you mainly using your platform rack for?

by: Jack 06/23/2021 One Year Later

This system is great. Have a 6’ rack mounted to it and it easily supports 200-300lbs of dynamic load a d 700+ static load without issue.

I’ve had this rack for over a year on our 2012 MW3 Jeep Wrangler Rubicon Unlimited. It has been awesome. The system works so well with my platform that we’ve done multiple trips on the Alpine Loop and the entire Rim Rocker Trail with a RTT and other essential gear with no squeaks rattles or movement. Supports the tent plus my family of 3+ without drama. Awesome system.

Way better for camper shells than tracks.

by: Tim C 06/21/2020 One Year Later

I love how this rack system uses the existing holes in the roof for mounting. Exactly what I was looking for. It makes for a very clean look.

by: Doug 02/01/2023 One Year Later

Just as I had expected. Top quality and no rust. A bit scary drilling the holes in your top but all went well. Their anti theft allen screws could use an upgrade.

by: Jim 09/23/2021 One Year Later

This is a pretty great platform. It has held up fine, doesn't leak, and wasn't too bad to install myself. It looks nice, and is there when I need it.
