Is this right for you? Product Expert Kathleen M says:

Yes, if you:

  • Are looking to save a little space on your roof so you can haul more gear in addition to your boats
  • Often get out on the water with a friend and want to easily haul both of your kayaks
  • Park in the garage and need a carrier that can fold down and out of the way

No, if you:

  • Have a taller vehicle where it will be tricky to reach at least one of the kayaks mounted, if not both, when you haul two at once
  • Worry about the rack getting snatched if you leave it on your roof while you’re out paddling
  • Need a place to stash your paddles on the rack - this 2-boat version doesn't allow that
This J-style kayak carrier allows you to transport 1 or 2 kayaks safely and securely on your roof rack. The space-saving cradle system mounts to most crossbar styles and folds down for storage. Includes tie-down straps. Lowest Prices for the best watersport carriers from Rhino Rack. Rhino-Rack 2 Kayak Carrier w/ Tie-Downs - J-Style - Folding - Side Loading part number S512-S512X can be ordered online at or call 1-833-496-1390 for expert service.

This J-style kayak carrier allows you to transport 1 or 2 kayaks safely and securely on your roof rack. The space-saving cradle system mounts to most crossbar styles and folds down for storage. Includes tie-down straps.


Very solid product. Able to easily install and use. Really liked that it came with all the tie downs.


I searched a lot of websites before finding what I needed on for my 2012 Suzuki GV. I was looking for the proper mounts to install a Kayak rack system. Because my vehicle has a built in rail system it was very confusing what was needed. Thank you etrailer for hooking me up with the appropriate parts for the Rhino system, it worked great!


The Rhino-Rack 2 Kayak Carrier I ordered from etrailer was easily reviewed and ordered from their website and ALL communication relative to order confirmation and extreme detail included in their tracking was nothing short of phenomenal! The items were packaged with care and arrived intact. These fit our basic Lexus crossbars and is the perfect product for carrying our two (2) kayaks. My hat goes off to the great folks at etrailer -- It doesn't get any better than this!!!


This has been a wonderful kayak holder for us. I love how I can fold it down and my STI no longer looks ridiculous and maybe even slightly still sporty even with a kayak holder system. It’s very strong and easy to use. The only downside is it has no theft deterrent or security locking at all. Absolutely anyone can come remove this quickly and easily without looking suspicious. Get some sort of lock like a zip lock with steel core perhaps if you are even slightly worried about theft.


Good quality product , very easy to install. I am 5 ft 9 and it is not easy to toss a kayak on a small suv. Beware of over-estimating your abilities is you Are a senior


This is not a great fit for a truck. The main carrier works very well and I word suggest that instead of getting the extension get another folding rack. Using the the extension forces you to reach all the way across the roof, which is difficult to do while trying to use the included straps. Would work very well for a small compact car that you can reach from the ground.


Worked great. Never ran into issues. De pendable.


Received all items ordered in one box, in excellent condition and in a timely manner. I just completed installation of the rack, the extension rack for an additional kayak and anchor strap locations on my 2009 RAV4, with Aero crossbars. No road test yet, but the rhino rack looks solid and fits well! Thanks again!


Everything man it’s straight up to the car I hold two kayaks on my roof rack and my kayak holders over 1000 miles and everything was great


Great product. Sturdy, easy to install, secure for luggage


A great carrier for two kayaks. It holds up well on long trips.


Quick shipping, great communication and the product is everything I could have wanted


Product was delivered on time and in good condition at a competitive price. Dual kayak rack fits OEM Kia crossbars perfectly. Ample tie-down straps. Simple, hassle-free installation in just a few minutes. Quality piece. Highly recommend this product and etrailer.


Just put the racks on the Subaru Crosstrek two days ago and strapped in the HiLife hybrid kayak/sup boards. Excellent product. Easy to adapt and easy to install. Super secure fit and worked well for the trip to the coast. Fit my aftermarket crossbars perfectly. These racks be bought anywhere, but I cannot recommend etrailer enough as the source. Excellent customer service, excellent follow through, and they back the products they sell. If you need information, they are there.



Quick delivery, easy install. Holds two kayaks nicely. Quality product.

Use it frequently, no deterioration after one year.

As always, etrailer processed and shipped my order swiftly. I haven't loaded with kayaks yet, but given my high esteem for Rhino Rack products and its sturdy construction, I have high hopes.


They were backordered for about 1 month which was annoying but now thay they are in I love the product and have had no problems with it thus far. Easy install


Easy to install. Solid and stable carri er.


Excellent quality product. Very easy to install. Would highly recommend!!
