      Versatile for 2 kayak mounting

      I bought the JLow system for the reasonable price and versatility in mounting 2 kayaks. You could theoretically mount a 3rd kayak if your vehicle has a wide roof and you stack the 2nd and 3rd flat (depending on the boats you’re carrying). The straps are pretty basic and as one reviewer pointed out, the brackets aren’t stainless steel. Of course you want to spread your roof racks far apart and use the bow and stern tie downs with bow in the front so you’re not scooping wind into the open bow. Regardless, you should use a cockpit cover to avoid any wind force. Another reviewer mentioned the wind noise when the cradle is down. Don’t know why Yakima didn’t test that issue and I don’t like to put mine up cuz I might forget about it when pulling into my garage or other parking garage around town. My solution is to cut pieces of a pool noodle, put a half-round under my crossbar and a narrow cross section wedged into the crack between the bracket mount and folding bar. Anything stuck in that gap will eliminate the noise.

      Awesome in high winds.

      I have two Eddyline Equinox (14’). Just returned to AZ from a 3000 mile round trip to the Oregon Coast. Had to evacuate Lincoln City and drive south through insane wind and smoke, along with constant semis, on I 5 (not my first choice, but the only road open). The J Lows, attached to factory Subaru Outback crossbars, were absolutely rock solid the whole way. I did add the Subaru sunroof visor, which removes the whining from the racks, both deployed and folded. I never leave racks on the car, as the AZ sun will eat them up. J Lows are so easy to remove, it is a no brainer to take them off when not in use. Absolutely love these racks.


      I’ve used the JayLow twice to transport our kayaks. Set up was not too bad, but right away as we tightened the straps holding the kayaks in place the gray rubber the kayaks are seated in come out of the mount. For the price of these mounts I didn’t expect that sort of defect. I purchased two pairs from different stores and each set did the same thing. Disappointing.

      Beware Saltwater use!

      The bar, bar screws and clamp screws are carbon steel and will rust quickly when exposed to salt water. These should ALL be stainless steel or anodized marine grade aluminum as kayaks are commonly used in salt water. Same goes for strap cam clamps.

      Good so far!

      I bought these and have taken them on a few trips so far but have only had them for a few months. I got them when Yakima was having their great sale on their roof racks and accessories and we have two kayaks so I figured buying a rack that allows me to take two will save me some cash. They are super easy to put on and take off and take only a few minutes each. It is great you can fold them down when not in use. Quality seems great. I also have the locks for added security. I have had no issues as of yet with these. I have read other reviews about faulty locks but mine have been okay thus far transporting two kayaks. I do use bow and stern ties with my boats for added security. I do not notice any crazy whistling with or without the boats. I love them so far! The only reason I did not five 5 stars is that I haven't had them for a long time so I think time will tell!

      Should be called the Banshee

      They work great for carrying a kayak or two. But for around $200 I would expect Yakima to put a little effort into aerodynamic optimization. These howl like crazy when folded, to the point I just leave them open all the time. On a 2015 Kia Forte with a Corebar setup the recommended Yakima windshield didn't help the JayLow noise significantly. A couple strips of 1/4" adhesive foam did more, but even so it's annoyingly loud at 40mph and over. Also the black cushioning material on the uprights leaves marks on my lighter colored boat, although they scrub off without too much difficulty.


      The first time I took my kayak out with these racks within 20 minutes of my drive the front rack's lock I guess decided to unlock, which pushed the front half of the kayak off of my car. I was on the highway, and it was my first time driving with my kayak on my car to begin with, so not a good impression. Thankfully I was able to have someone come pick up my kayak and take it back because I had another hour drive to where I was supposed to be going. I will take it out one more time and test how it works again on a less crowded highway before I decide to ditch it. But this time I will definitely take someone with me with another car that can hold the kayak incase it decides to snap closed agin.

      Faulty lock disaster

      I recently purchased the JAYLOW system to transport a 1-person 9.5' Kayak. They looked great and made sense with the ability to fold down. However, while using only for the second time, the red handle latch disengaged, the lock failed, and shifted the Kayak off of the side of my vehicle. This occurred while driving on a busy highway at 65 mph. I had to pull over on the narrow shoulder of the busy highway to assess the situation and was very concerned about my safety as well as the safety of the other motorist. I didn't want to take any chances with the JAYLOW latch disengaging again, so I tried to store the Kayak in my SUV and accidently cracked my windshield in the process. I was able to strap-down and exit the highway to the nearest REI store and purchases the JHOOK model instead. I'm now unable to pull into my garage since it can't fold-down, but it's safer and I don't want to take another chance with the JAYLOW system. I do not recommend this product, it was faulty. Aside from a $400 windshield replacement, it could've been a lot worse for myself and other drivers on the road. Please be careful!

      Jaylow Kayak Rack

      I purchased a pair of Jaylow Kayak Racks through Rack Ware House and I find the product to be poorly constructed. The grey pad the kayak rests on came partially out of one of the Jaylow racks and is starting to work its way out of the second rack. I have only used the Jaylow racks two times. Rack Ware House contacted Yakima and I received instructions to loosen a screw on the bottom of the rack and tuck the pad back in, then tighten the screw. The lip of the pad that holds it in the rack is so small that this suggestion does not address the issue at all. Yakima writes that their (alleged) warranty does not cover this type of defect. I would not recommend this product due to poor design and Yakima does not honor there warranty commitment. In conclusion, I would be suspicious of any Yakima product in the future due to their poor warranty pledge.

      Kayaking- Carrying Heaven!!!

      ME: Roundhead for the last 25-26 years, with exception to my Dodge Dakota Truck Cap that came with a Thule Rack, I have experienced both major brands. I started with the old fold down Inverted U-shaped Kayak Stackers, which I loved. Since then I have gone to Land Sharks & Hully Rollers. But for my new Jeep - I decided to try the Jaylow so I could carry 2 touring boats if need be without taking up all the roof space. Wow. WOW. WOW! So easy to install. Jaylows came complete with straps and front/rear tie downs. Picking the boat up from the side could not get any easier to load. No more dealing with rollers and getting my boats around satellite antennas or rear spoilers. When I got to my destination, The boats came off quickly and the Jaylows popped off in about 1:30 seconds - I locked them away in the back and was on the water in a flash. Never, has this been so easy. I was worried about road noise between my Jet Stream bars and the Jaylows. Virtually nothing. A slight whistle a couple of times when going over 85 MPH. (I know... I know.... it was crazy keeping pace with traffic in NJ/NY)). Simply a wonderful product and I cannot say enough good things about them ... If you are on the fence, and you might need roof space, do yourself a favor and check them out. And lest anyone think I am spry enough to throw my boats around, I will be 60 next year and these things are the cats pajamas!!!
