  • Low Profile Roof Platform Recommendation for 2020 Toyota 4Runner with Factory Side Rails
    For your 2020 Toyota 4Runner with the factory side rails, I recommend the Yakima LockNLoad Platform Roof Tray 60" Long x 54" Wide, part # Y05045. It's pretty low profile at only 4 inches tall, and it will not interfere with your sunroof, since it will sit right behind it. I've attached a couple of photos so you can see for yourself. To attach the platform, you'll need the LockNLoad SL Adapters # Y05042-2 (qty 4), and TimberLine Towers # Y33TR (qty 4). This will add approximately another...

    The Rhino-Rack Backbone Mounting System for Pioneer Platform - Toyota 4Runner # RRRT4B1 is a fit 2010-2018 models as that is all they have been tested on according to my contact at Rhino Rack. There are a couple options for a Pioneer Platform compatible with your 2004 4Runner. I confirmed with them the 60" Long x 49" Wide # JA9133 will fit your vehicle.

  • How to Mount 60 Inch x 49 Inch Rhino-Rack Pioneer Platform Rack to 2018 Toyota 4Runner
    I spoke with my contact at Rhino-Rack regarding the Rhino-Rack 60 Inch x 49 Inch Pioneer Platform Rack # RR35TB and your 2018 Toyota 4Runner. She stated that in order to use this size Pioneer Platform Rack on the roof of your 4Runner, you will need to actually keep the factory side rails and use the Rhino-Rack SX Series Legs # RRSX100 to mount the Platform. The Rhino-Rack Backbone Mounting System # RRRT4B1 that is designed for your 4Runner is only compatible with the larger size Pioneer...

  • Correct Rhino-Rack Pioneer Platform Roof Tray and Backbone Mounting System for a 2022 Toyota 4Runner
    I went ahead and checked with Rhino-Rack, and the good news is both the Rhino-Rack Backbone Mounting System for Pioneer Platform # RRRT4B1 and the Rhino-Rack Pioneer Platform Roof Tray # RR25TB are compatible with each other as well as your 4Runner. This Pioneer tray measures 84" long and 49" wide, however if you want a smaller platform you could use the Rhino-Rack Pioneer Platform Roof Tray # RR45TB which is 76" long and 49" wide. This platform is also compatible with the backbone #...

  • Recommended Rhino Rack Pioneer Platform for my Toyota Sequoia 2016
    I have a great solution but there is no available backbone system for your 2016 Toyota Sequoia from Rhino Rack. Instead the Rhino-Rack Pioneer SX Platform Rack part # JA8011 is a confirmed fit for your 2016 Toyota Sequoia this is designed to clamp on to your already existing raised factory side rails.

    The correct part number for the Rhino-Rack Backbone Mounting System RT4B1 is # RRRT4B1. As for the 52107F, I can confirm for you this part is the 84" Long x 49" Wide Rhino-Rack Pioneer Platform Roof Tray # RR25TB.

  • What Roof-Mounted Platform do You Recommend for My 2022 Toyota 4Runner?
    I have a great platform solution for you. Unfortunately, I confirmed with Yakima that they have not confirmed a fit of the LockNLoad Platform # Y05045 on your factory crossbars on your 2022 Toyota 4Runner. With that being said, Yakima also has not tested the fitment of the LockNLoad to your rails if you remove the crossbars from the setup. This is because manufacturers often do not test these applications because their reasoning is you will always use your factory crossbars with any application....

  • Rhino-Rack Backbone Mounting System for a 2011 Lexus GX 460
    Hey Randy, thanks for reaching out! The correct Rhino-Rack Backbone Mounting System for your 2011 Lexus GX 460 is the Kit # RRRTPB1. Please note this will require the removal of any OEM rails that may or may not be installed on your vehicle. The Kit # RRRT4B1 for a 5th Gen 4Runner won't fit your Lexus.

  • Rhino-Rack Pioneer Platform Roof Rack Mounting To a 2021 Ford Explorer
    Currently the only mounts for your 2021 Ford Explorer to add a Rhino-Rack Pioneer Platform Roof Tray # RR95TB are the Rhino-Rack SX Series Legs # RRSX100.
