    • Clamp-on equipment like bike racks, kayak carriers, cargo boxes, and roof top tents
    • Mount accessories like off-road lights, load stops, or a ladder roller in the top channels
    • Add eye bolts or additional lights to the bottom channels
  • Rubberized strips in the crossbars' top channels reduce wind noise and drag
  • SideBar rails (sold separately) provide more carrying space for off-road and utility accessories
  • Built-in tie-down points on uprights and crossbars make it easy to secure gear
  • QuickChange system allows rack to be installed and removed in minutes - no drilling required
    • Simply slide tonneau adapters onto the tonneau cover's tracks and tighten to the pad and tower
    • BedGrip clamps secure to bed rails on most common truck beds
    • Etched measurements on crossbars help center the rack
  • Same Key System (SKS) lock cores secure uprights to your truck
    • SKS cores can be swapped out to make all your Yakima products keyed alike

Tonneau Cover Compatibility

This truck rack includes adapters that let you fit the uprights to the top of your tonneau cover. First, slide the T-bolts into the tonneau cover's side rails. Then, place the adapter bases and uprights over the bolts and secure them with the included hardware. Once they are in place, you can proceed with the rest of the rack installation.


The adapters are compatible with the following tonneau covers:

  • Retrax XR
  • Ford Embark LS
  • Pace Edwards UltraGroove (except for 2004 and newer Ford F-150 covers)

Yakima Off-Road Rating

This truck rack was tested to ensure that it is able to handle regularly adventuring over rough terrain. Yakima extensively tested it with worst-case-scenario lab simulations and real world driving to make sure it exceeded ISO requirements. This rack is built to handle evasive maneuvers, swerving, speed bumps, emergency stops, and whatever else you encounter while off the beaten path.

I think the bottle opener feature advertised should work! I emailed about that shortly after installing the product, even sending photos, and no one from your company every reached back out to me to resolve the issue.



by:

Received complete rack with NO parts missing. The Outpost HD rack fit my ‘17 Tacoma great with no installation issues.



by:

Rack system works very good. Easy to take off and on my F150. Wish it was more adjustable to lower the system a few inches. Also because of the bed formation cannot place anywhere on the bed. Overall it is stable and rides well



by:

Very sturdy, and setup was a breeze with all of the required tools included.



by:

Thanks etrailer for the help in getting this! Couldn't find the Tonneau adapter in stock anywhere. Thankfully etrailer let me place an order and they tracked down the part for me. GREAT communication by the etrailer customer support team keeping me updated on the status of this order. It took a while due to delays from Yakima, but it's now installed and I'm very happy.



by:

Very strong and safe for my intended ap plication.



by:

The products durability is great. Find the right height for my truck was more challenging. I wish I had not gotten this particular product. Doesn’t go above my truck bed cab.



by:

Best online company I've ever dealt with. Website and follow-up outstanding. Great customer service.



by:

Very strong rack, well built, fit and finish exactly what I needed

  • What Waill the Usable WrapAround Crossbar Are be when The Yakima Outpost is Installed
    While it can vary slightly the Yakima OutPost HD Overland Truck Bed Rack w/ Tonneau Cover Adapter part # Y01152-5955 will give you a usable wrap around area that is 5-6" smaller than the width of your truck bed. This on your 2019 Chevrolet Colorado should be well above the requirement you have for your Thule rack that needs 24" of bar space. As another option some Thule products come with both wrap around or slot adapters that allow you to mount your accessories in the slots of the bars...

  • Recommended Ladder/Roof Rack for Retrax XR Tonneau Cover To Use with Rooftop Tent
    I recommend using the Yakima OutPost HD Overland Truck Bed Rack part # Y01152-5955 with the Retrax XR Tonneau Cover. This setup provides you with up to a 300 lb capacity and it has a low profile design which is ideal for tents. Unfortunately, the Yakima BedRock HD Truck Bed Rack won't work since it attaches to the bed rails. The OutPost comes with an adapter for the XR rails.

  • How To Use Rooftop Tent with Rack On Retrax XR Series Tonneau Cover
    I have some great roof rack options compatible with the Retrax XR Series Tonneau Covers. The most heavy duty option would be the Yakima OutPost HD Overland Truck Bed Rack part # Y01152-5955 which offers up to a 300 lb capacity. Unfortunately, you won't be able to obtain more than this as the mounting rails are the limitation, not the rack. That said, most rooftop tents have built-in ladders which help bear weight. The Yakima Skyrise Rooftop Tent part # Y07436 for example only requires that...

  • Correct RetraxPRO XR and Yakima OutPost HD Fits for a 2016 Ram 3500 Long Bed
    You are correct that the Yakima OutPost HD # Y01152-5755 with the 60" bars are too small. You'll want to use either the set with the 68" bars which is part # Y01152-5855 or the 78" bars which is part # Y01152-5955 instead. These will be wide enough for your 2016 Ram 3500 with the RetraxPRO XR Hard Tonneau Cover w/ Trax Rails # RTT-80233.

  • Best Powered Tonneau Cover For a 2024 GMC Sierra 1500 Denali With 6-1/2' Bed
    I recommend installing the PowertraxONE XR Hard Tonneau Cover # RTX83YR on your 2024 GMC Sierra 1500 Denali with a 6-1/2' bed. This cover is powered and has polycarbonate slats which won't fade in the sun like vinyl or scratch easily like painted aluminum rails. It also has T-slots built into the side rails which allow you to add a Yakima OverHaul Ladder Rack # Y01151-5955 or Yakima OutPost HD Overland Truck Bed Rack # Y01152-5955.

  • Will Yakima OutPost HD Fit 2017 Ford F-250 with RetraxPRO XR Tonneau Cover
    The Yakima OutPost HD Overland Truck Bed Rack # Y01152-59 will the RetraxPRO XR on your 2017 Ford F-250 Super Duty, part # RTT-80383 for a short bed or part # RTT-80384 for a long bed, when you use the Adapter Kit # Y01155. The OutPost HD and Adapter Kit are available together as part # Y01152-5955 as well so you don't have as many parts to order. The RetraxPRO XR and Yakima OverHaul/OutPost HD setup is one of my favorites because of how much versatility you get with these kitted together.

  • Are There 2-1/2" Receiver Tube Shanks With 5 Or 7 Holes Available
    We carry a large selection of shanks that fit a 2-1/2" receiver, like the Equal-i-zer Weight Dist Shank - 2-1/2" Hitch - 10" Rise/6" Drop # EQ90-02-4900, but the amount of holes isn't always going to mean it has a large enough drop or rise since the holes could sit different in the shank. I've attached a link to all of the shanks that fit a 2-1/2" receiver but I'd be happy to find you the correct fit if you could tell me which weight distribution hitch you're needing it for and the drop...

  • Most Heavy Duty Rack To Use with RetraxPRO XR Hard Tonneau Cover on a 2019 Ford F-150
    I do have options for you but the tracks on the RetraxPRO XR Hard Tonneau Cover part # RTT-80374 are simply just not strong enough to use a rack that has a 800 - 1,250 lb weight capacity. The most you will be able to carry using the tracks on the above is 300 lbs. For this, you will need to use the Yakima OutPost HD Mid-Height Truck Rack part # Y01152-5955. If you don't already have the RetraxPRO XR Hard Tonneau Cover then you can use the BAK Revolver X2 Hard Tonneau Cover part # BAK39327...

  • What Roof Rack Kits Will Work with the RetraxPRO XR Hard Tonneau Covers
    Yes, I have listed for your below the roof rack systems from Rhino-Rack, Thule, and Yakima that will fit the RetraxPRO XR Hard Tonneau Covers like part # RTT-80243 for your 2019 Ram 1500. Rhino-Rack Vortex Crossbar System part # RRVA180B-RRRLT600 Yakima OverHaul HD Adjustable Truck Bed Ladder Rack part # Y01151-5955 Yakima OutPost HD Mid-Height Truck Rack part # Y01152-5955 Thule ProBar Evo Crossbar System part # TH713700, part # TH460R, and part # THKIT3101 (part # TH450400) I recommend...
