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



by:

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



by:

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:

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:

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



by:

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



by:

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.



by:

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.

Great prices on great products!

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.



by:

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).

Backbone installed- waiting for feet to attach crossbars



by:

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.



by:

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.



by:

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.

  • Will the Gutter Mounts # RL150S13-3 Attach to a Rhino-Rack Pioneer Platform?
    I went ahead and reached out to my contact at Rhino-Rack, and she confirmed that the Rhino-Rack Roof Rack Legs - Gutter Mount - 5-15/16" Tall # RL150S13-3 will technically attach to a Rhino-Rack Pioneer platform. However, Pioneer Platforms are customized to fit certain roof dimensions, and I cannot recommend which platform you will need for your vehicle. In order to give you the proper fitment and recommendation, please feel free to respond to this answer with the year/make/model/roof...

  • Weight Rating for the Rhino-Rack Gutter Mount Roof Rack on a 2022 Jeep Wrangler Unlimited
    You are correct, the Rhino-Rack SG Roof Rack for Rain Gutters with Vortex Aero Crossbars, # RRSG59 that you linked to is 88 lbs. But don't worry, we have other options. I suggest you consider the Rhino-Rack Backbone roof rack system that starts with the, Backbone System, # RRRJLB1 using Rubber Bases, # RRQMFK06, Spacer Blocks, # RRQMHD05-2 and Quick Mount Legs, # RRRLT600 along with 59" HD Crossbars, # RB1500B-2. This will provide you a heavier rating of 175 lbs. however, please check...

  • What is the Weight Rating of the Rhino-Rack Gutter Mount Roof Rack on a 2022 Jeep Wrangler Unlimited
    The weight rating for the gutter mount system from Rhino-Rack is really 88 lbs for your 2022 Jeep Wrangler Unlimited with the hard top. Since there are many other options out there with a higher rating I recommend going a different direction. For your application I recommend the Rhino-Rack Backbone roof rack system which consists of the following: 59" HD Crossbars - # RB1500B-2 Quick Mount Legs - # RRRLT600 Backbone System - # RRRJLB1 Rubber Bases - # RRQMFK06 Spacer Blocks - # RRQMHD05-2 This...

  • Roof Platform Rack that Fits Nissan Armada 2008-2024
    You didn't mention what year Armada you have but the 2015 Nissan Armada is a first gen so while we have a platform solution we don't have a Rhino Rack. So what we have that is a fit is the Front Runner Slimline II platform part # FR48YJ which is 85-1/4 inch by 53 inch. This platform so far fits 2008-2024 Nissan Armadas. This would work great to support a tent like you are looking for.

  • What Backbone System Works w/ a 2023 Jeep Wrangler 4xe?
    There are tons of options for Jeep's so I would be happy to point you in the right direction. The correct back bone system with a pioneer platform for your 2023 Jeep Wrangler 4xe hard top is the item # JB0893 you were looking at. The Rhino-Rack Pioneer Platform Rack with Backbone Mounting System item # JB0893 measures 72" long x 56" wide. It has a 264 lbs capacity and weighs 94 lbs. If you are wanting a back bone system that mounts traditional crossbars you will need the following...

  • Which Crossbars for Rhino Rack BackBone System to Use Thule Hullavator
    The best solution to use the Thule Hullavator # TH898 with a Rhino Rack Backbone system would be to use Vortex Aero bars like the Rhino-Rack Vortex Aero Crossbars - Aluminum - Black - 65" Long - Qty 2 # RRVA165B-2 (if you're using 3 bars on this setup you'll also need to order the # RRVA165B for a single bar). The extra length on these bars compared to the 59" long bars will give you the extra clearance you need to get away from the side of your Jeep with the Hullavator. You can use the...

  • Can Hard Top Be Removed with Rhino-Rack Backbone Mounting System Installed on Jeep
    The Rhino-Rack Backbone Roof Rack Mounting System # RRRJLB1 is designed to reinforce the structure of your Jeep's hard top so you can carry more weight but it won't physically interfere with the removal of the hard top. Once installed you will still be able to take off and re-install the hardtop on your Jeep without issue.

  • Rhinorack Backbone for 2018 wrangler JL With 3 Vortex Crossbars
    To use the Rhino-Rack Backbone part # RRRJLB1 with 3 Vortex Crossbars on the 2018 Jeep JL Wrangler you will need part # RRRLT600H with part # RRRLT600, 3 sets of spacers part # RRQMVA05, part # RRQMFK05 for the rubber bases and part # RRVA150B-3 for the three bars.

  • Rhino Rack Pioneer Platform that Fits 2018 Jeep Wrangler Unlimited
    The mounting kit needed to fit a Rhino Rack Pioneer Platform to the roof of a 2018 Jeep Wrangler Unlimited is the part # RRRJLB1 which you could potentially be used with the smaller Pioneer Platform # JA8688 but you are going to end up having to get the # RRQMHD05, the leg kit # RRRLT600 and the # RRRLT600H. I'd go with the larger # JB0893 though as it will fit and is the most cost effective solution. The picture I attached shows what the # JB0893 looks like installed.

  • What Heavy-Duty Crossbar Setup do You Recommend for My 2018 Jeep Wrangler Unlimited with Hard Top?

  • Recommended Roof Rack System for 2019 Jeep Wrangler Unlimited JLU
    As a fellow Jeep owner I've got some experience with this, and the issue you're going to run into is that the hard tops on Jeep JLU and JKU are not designed to hold any weight because of their lack of internal support. As I'm sure you're aware, they're just a fiberglass shell, so your best bet is going to be starting with a RhinoRack BackBone # RRRJLB1. This kit will add mounting points for a roof rack, while reinforcing the shell of your hard top that will allow you to safely carry weight...
