Purchased a Rhino Rack custom fit rooftop system, along with the kayak rack to hold two kayaks and the Swagman rv bike rack. Made several trips and they all work great! Included photos to share. 475958

I purchase the extension for the Rhino Rack that allows for 2 kayaks to be loaded onto one J-cradle. It works fine, and because I only use it occasionally when I'm carrying 3 kayaks, I am please with it. The only problem is that it is a bit unwieldy to load both kayaks in the upright position because the straps on the one closer to the center of the car have to be in just the right spot so that the one toward the outer edge of the car can be strapped down. Just takes some getting used to and a good helper. 281754

  • Is Expansion Arm for Rhino-Rack J-Style Kayak Carriers # RRS512X A Set of Two
    Expansion Arm for Rhino-Rack J-Style Kayak Carriers # RRS512X contains 2 of the extension pieces so you would not have to buy 2 of them to use with carrier # S512.

  • How to Carry 2 100 lb Kayaks on 2017 Toyota RAV4
    None of the roof rack options we offer for the 2017 RAV4 offer a capacity greater than 165 lbs, so although I don't have a solution for carrying the kayaks on the roof of your vehicle, we do have a solution. Your best bet would be a small kayak trailer like the Malone MicroSport, part # MPG464-LB. The trailer's crossbars are rated up to 500 lbs, so they'll handle your kayaks without breaking a sweat. For a properly rated carrier (if you don't already have them), I'd recommend the etrailer...

    Expansion Arm for Rhino-Rack J-Style Kayak Carriers # RRS512X contains 2 of the extension pieces so you would not have to buy 2 of them to use with carrier # S512. The 34 inch wide kayaks would not be a problem provided that the combined weight of both kayaks is no greater than 99 pounds.

  • Roof Rack and Kayak Carrier Recommendations for a 2004 Mercedes C240
    To safely carry your 2 kayaks on your 2004 Mercedes C240 you will first need a roof rack since the vehicle does not have one. The most cost effective option that fits your vehicle is # RR36ZR for 2-door models or # RR29ZR for 4-door models. With a roof rack installed you could then use the J-style carrier # S512 which by itself holds one kayak. But it can hold 2 kayaks by adding the expansion arm # RRS512X. The carrier has a capacity of 99 pounds.

  • Recommended Roof Rack, Cargo Box, and Towing Setup for 2017 Honda Pilot EX L
    Congrats on the purchase of your 2017 Honda Pilot. For your roof rack, the naked roof will require the custom door clips instead of the other options you mentioned. I recommend going with the Rhino-Rack ROC25 Roof Rack for Naked Roofs - Vortex Aero Crossbars - Aluminum - Black # RR73XR which is a clean look and comes with the locks to secure the rack to your roof. The bars will be 31-1/2 inches on center so I recommend using the Thule Pulse Large Rooftop Cargo Box - 16 cu ft - Matte...

  • Will RhinoRack 2 Kayak Carrier Work On Factory Crossbars of Honda Ridgeline Truck
    The Rhino-Rack 2 Kayak Carrier (the 2 kayak carrier is made using # S512 paired with Expansion Arm # RRS512X ) will mount to the factory crossbars on the 2019 Honda Ridgeline without any problems, but from what I was able to find from my research, it might not be able to carry the weight of your Hobie Mirage kayaks. Since this carrier has a 110-lb weight limit, and it appears that your kayaks weigh about 60-lbs each, the Rhino-Rack carrier may not be the best option for you. If you weigh...

  • 2015 Jeep Wrangler Roof Rack with Rhino Rack Vortex RLT600 for Rhino-Rack 2 Kayak Carrier
    The Rhino-Rack Quick Mount Legs for Vortex Aero Crossbars - RTC and RT Roof Rack Tracks - Qty 4 # RRRLT600 are designed to fit the tracks like # RTC16. Another popular option is to use the backbone roof mounting system for Jeep Wrangler hard tops # RRRJKB2 and rubber bases # RRQMFK06. Then you will simply use crossbars like the 59 inch # RRVA150B-2 to complete the roof rack. This complete system will allow you to use most roof accessories like the 2 Kayak Carrier # S512 and RRS512X....

  • Recommended Roof Rack and Kayak Carrier for 10 Foot Sit-In Kayak on a 2012 Volkswagen Passat SE
    I do have a solution for you, but I wish there was a way to transport your kayak with a hitch mounted bike rack. Currently, none of our manufactures have come up with a way to do so; which means we will need to outfit your Passat with a roof rack and kayak carrier. The roof rack for your 4-door 2012 VW Passat SE, I recommend is the Rhino Rack Vortex Aero Roof Rack # RR72MR. For your 10 Foot Sit in Kayak, I recommend the Rhino Rack J-Style Kayak Carrier # S512. This rack will securely...

  • Recommended Roof Rack And Kayak Carrier For 2015 Chrysler Town And Country
    We don't have any manufacturers that utilize the OEM fixed point system. If you are open to a clip on style attachment that is a custom fit for your vehicle, I recommend the Thule system. This roof rack consists of the Thule Wingbar Load Bars - Aluminum - 53" - Qty 2 # TH711420, the Thule Rapid Traverse Roof-Rack Foot Pack # TH480R, and the Thule Roof-Rack Fit Kit for Traverse Foot Packs # THKIT1043. Another option is to see if there is a carrier compatible with your current crossbars....

  • Recommended Roof Rack With Locking Crossbars for 2014 Nissan Rogue
    For your 2014 Nissan Rogue I highly recommend the Rhino Rack ROC25 # RR85QR. This roof rack has locks built into the crossbars like you wanted, have an elliptical shape with rubberized Vortex strips to greatly reduce the amount of wind noise you might otherwise encounter and measure 3-1/8" wide x 1-3/16" tall. This rack has been highly praised by our customers who have it, with well over 250 reviews giving it a nearly 5-star rating, as you can see in the "Reviews" section on the product...

  • Recommended Roof Rack And 2 Kayak Carrier For 2013 Nissan Rogue
    For your 2013 Nissan Rogue, the Rhino-Rack roof rack consisting of the Rhino-Rack 2500 Roof Rack DS126B and the Custom DK Fit Kit # DK146 is no longer available, but would have been all you needed. Rhino Rack has replaced that system with the roof rack consisting of crossbars # RRVA126B-2, legs # RRRLKVA, and the same fit kit # DK146. If you want to haul two kayaks, I recommend the Rhino-Rack J-Style Kayak Carrier - Folding - Universal Mount # S512 with Expansion Arm for Rhino-Rack...

  • Roof Mounted Kayak Carrier to Fit Thule AeroBlade and Yakima Round Roof Rack Crossbars
    Rhino Rack offers a reasonably priced Universal Mount J-Style Kayak Carrier that would work great for you. There's a folding model that folds down fairly flat when it's not being used, part # S512. If you wanted to carry two kayaks, there's an expansion arm available as part # RRS512X. If you aren't interested in a folding carrier and only need to carry one kayak, part # S510 would be a good choice. The carriers include bow/stern tie downs and 2 straps to secure the kayak to the roof...

  • Best Rooftop Kayak Carrier For Two 10 Kayaks On A 2016 Chevrolet Silverado 2500
    In order to carry two 10' kayaks with a 2016 Chevrolet Silverado 2500 while towing a 5th wheel camper, you will have two options to consider. The first entails the use of a roof rack with rooftop kayak carrier. The second option consists of a front mounted hitch and hitch mounted load extender. For a roof rack, I recommend the Rhino-Rack Vortex Aero Crossbars part # RRVA150B-2 and # RRRLKVA. This model fits both crew and quad cab variants of the 2500 featuring an aluminum light-weight...

  • Carrying 3 Kayaks While Towing a Trailer with a 2015 Ram 1500 Crew Cab
    It can be tough to bring along all your gear when also towing a trailer but we do have some solutions for you that will allow you to bring all the kayaks with you. If the trailer is a bumper-pull and not a 5th wheel or a gooseneck then a great option is a ladder rack. Ladder racks aren't just for ladders anymore! Take a look at the Rola Haul-Your-Might ladder rack # 59742. This rack has a 400 pound capacity and aluminum bars to resist corrosion. Since the bars are the same size as the...

  • Recommended Roof Rack And 2 Kayak Carrier For 2015 Jeep Grand Cherokee
    For your 2015 Jeep Grand Cherokee, the roof rack system is somewhat dependent on the e-group or without the e-group. The e-group package has a chrome strip on the top of the side rails and the non e-group does not. I'll give you both fit options. For the roof rack without the e-group package, I recommend the Thule Wingbar Evo- Aluminum - Black - 60" # TH711520 , the Thule Rapid Traverse Roof-Rack Foot Pack # TH480R, and the Thule Roof Rack Fit Kit for Traverse Foot Packs # THKIT1656....

  • Kayak Carrier Recommendation for Carrying 2 Kayaks with 2018 Subaru Outback with Factory Bars
    The best solution we have would be the Rhino Rack kayak carrier part # S512 that you referenced with the expansion arm part # RRS512X to allow you to carry a second kayak. This rack has the highest weight capacities at 99 lbs and can fold down when not in use so it would be a great solution. This also fits the factory crossbars of a 2018 Subaru Outback Wagon as well.

  • Recommended Roof Top Carrier for 2 Kayaks
    For your 2 kayaks, the J-style carrier will hold your kayaks a little better than the post style. Out of the options you listed, the Yakima JayLow Kayak Carrier w/ Tie-Downs - J-Style - Folding - Side Loading # Y04073 will give the best support to one kayak per carrier, but all options will give good support for 2 kayaks. The decision is if you can them to rest on the crossbars or on each other. The Inno model you referenced has been discontinued so I can't compare that option. I...

  • Recommended Roof Rack and Kayak Carrier for Camper Shell on 2008 Toyota Tundra
    To install a roof rack onto the camper shell of your 2008 Toyota Tundra, I recommend the Rhino-Rack Roof Rack System - Track Mount # Y02-490B. This will include everything that is needed to install a roof rack, including two 59 inch long aero crossbars and two RTC-style tracks with dual C-channels that will allow for adjustable mounting points for the roof rack legs. Keep in mind that drilling into the camper shell is required to attach the tracks. This rack has a weight capacity of 220...

  • Recommended Roof Rack/Carrier Option for 2 Kayaks on 2014 Chevy Silverado 3500
    First, let's start with the kayak carrier. A kayak carrier system like # S512 used with the # RRS512X would allow you to carry two kayaks, while not using a lot of space on the roof. You'll next need to choose a roof rack to provide an attachment point for the kayak carrier. The roof rack solution you'd use will depend on whether your Silverado 3500 is a regular or a crew-cab model. For a crew-cab, I'd recommend an Vortex Aero rack from Rhino-Rack which is the most budget friendly...

  • Can 2 J-Style Kayak Racks Be Attached To A 2016 Acura MDX Factory Roof Rack?

  • Recommended Roof Rack, Ski Carrier, Bike Carrier & Kayak Carrier for 2015 BMW X3
    Let's start with the roof rack itself. Rhino-Rack offers an good looking and strong but economical rack for your vehicle. For black crossbars, you'd want to use part # RRVA126B-2 and the # RRSX026 roof rack legs. For silver crossbars, use # RRVA126S-2 and the same # RRSX026 legs. Rhino Rack offers many different accessories for carrying bikes, kayaks, skis and snowboards. To carry 2 pairs of skis or a snowboard, use the # RR572 carrier. For 4 pairs of skis or 2 boards, use # RR574....

You could use one J-style carrier and the # RRRWP03, but you could exceed the width of your crossbars. I recommend the Rhino-Rack J-Style Kayak Carrier # S512 along with the Expansion Arm # RRS512X. This lets you carry two kayaks side by side. You will need additional tie-downs like part # TH855XT. To make it easier to...

You can either get two sets or if you prefer, you can simply add the Expansion Arm for Rhino-Rack J-Style Kayak Carrier # RRS512X. This will transform that rack into a 2 kayak rack that will fit your factory crossbars.

With these 2 items you can carry 2 kayaks that together weigh up to 99 pounds.

    Rhino-Rack roof rack # RRSG60 is for a regular 2015 Jeep Wrangler. Since you have a 2015 Wrangler Unlimited you would need # RRSG59. To maximize the free space on the roof rack I recommend using kayak carrier # S512 with expansion arm # RRS512X. This set up will allow you to carry 2 kayaks. You might be able to use 2 sets of carrier # RR570 and carry the kayaks side by side but it depends on the width of the kayaks too. The bars are only 50 inches long. The saddle cradles can fit...

Then for your kayaks I recommend the Rhino-Rack 2 Kayak Carrier w/ Tie-Downs - J-Style - Folding - Side Loading # S512 with expansion # RRS512X.

For vehicles without the moonroof, the load capacity is 100 pounds. With OEM or aftermarket crossbars installed, you will need to follow this 45 pound or 100 pound limit, depending on what type of roof your model Explorer has. If you do not yet have a complete roof rack system, I recommend the Rhino Rack Vortex Aero Roof Rack....
