Bed Rack Tonneau Adapters

(3 customer reviews)


With this kit is finally possible to have an RCI bed rack with certain tonneau models, and retain full functionality!





  • Kit includes six brackets, designed to allow the compatibility of certain tonneau covers with any of the RCI adjustable bed racks
  • Confirmed to work with BAK Revolver models – List will be updated as we confirm more. Should be compatible with many hard or soft roll-up covers and retractable covers that do not have integrated T-Slot rails
  • May be compatible with certain folding hard panel covers however it will NOT be possible to open the cover without removal of rack. This is due to the shape of the bed rack, it would have to be square and 20-24″ tall for compatibility with these covers
  • Raises the overall height of bed rack by 3″
  • Optional holes for bolting through the bed cap, however not necessary for most applications
  • Product includes a heavy duty two stage black powdercoat finish
  • Our C-Clamps and Toyota Adapter kits are now sold in different quantities!
    • (SPORT) selection is for our Sport Bed Racks. This will include 4 adapters/clamps
    • (HD) selection is for our HD Bed Racks. This will include 6 adapters/clamps

*Not compatible with current Tacoma (non-adjustable) bed rack OR previous non-adjustable bed racks!

    Recently purchased with 12 inch adjustable bedrack to install on my 2018 Raptor with Backflip tonneau cover. It has first class fit and quality! This adapter fits perfectly under the tonneau rail. I wish I can upload pictures! Extremely happy with the decision and customer service is amazing! I can roll my tonneau cover all the way while having high quality off-road bedrack ! Can’t wait to start my overlanding journey!

    These are rock solid. With them bolted to my bedside, I can shake the entire truck just pushing on one of them.

    I have them on a ‘12 Tacoma with a bakflip revolver x2 and I did run into some compatibility issues. However, this was due to Bakflip’s design and not RCIs in my opinion. Thankfully the guys at RCI were able to walk me through drilling holes and mounting to the bed side with no modifications needed besides the holes. I do recommend at least a 2in carriage bolt if you plan on mounting the brackets using the top hole. Also consider lock nuts and washers if you go the bedside route.

    After drilling and getting the brackets torqued down, install of my bedrack was easy.

    -The adapters gave my 18″ a little more height so I wouldnt bang my head on the bottom of the RTT when open
    -Solid…once installed these did not move
    -“Could” work with some covers (see Cons)
    – Super easy install

    -DOES NOT work with 2020 Gladiator factory roll-up cover. The cover goes all the way to both sides of the bed edge and this adapter takes up some of that. I can see where other covers can work no problem…just not with the factory soft roll-up one
