The Thule TracRac SR Sliding Truck Bed Ladder Rack carries up to 1,250 lbs and slides the full length of your truck bed so you can position the uprights exactly where you need them. Whether you’re hauling ladders, lumber, or a kayak, the quick-release knobs let you move the racks forward or back in seconds. When you’re done, the uprights can slide together or come off entirely for full bed access. The 69-1/2" elliptical crossbars cut down on wind noise, so you can drive without the constant whistle that’s common with square bars.
The entire rack system is built from lightweight 6000-series aluminum that’s strong, corrosion resistant, and won’t weigh down your truck. A dual-stage powder coat adds even more durability—an electrostatic e-coat that clings tightly to the surface, followed by a clear coat that protects against scratches and keeps the rack looking clean. The combination of aluminum and powder coating means it stays sturdy and rust-free even after years of use.
The base rails mount directly into the stake pockets with no drilling required. Each side uses a wide base for extra stability, so there’s no need for additional bracing. The two T-tracks built into the rails let the uprights slide smoothly and lock into place wherever they’re needed. That means you can load long materials one day and move the racks out of the way for larger cargo the next.
Eight tie-down accessories come standard—four adjustable load stops that slide along the crossbar channels and four side cleats that bolt onto the uprights. The load stops keep ladders, lumber, or pipe in place, and the integrated loops give you secure points for straps. With multiple mounting slots on both the top and bottom of each bar, you can position tie-downs exactly where they’re needed to keep your cargo from shifting.
The elliptical crossbars and built-in airfoil strips at the front help manage airflow, reducing drag and cutting wind noise. The streamlined shape not only improves efficiency but also gives the rack a clean, finished look that blends in with the truck’s profile. At 27-5/16" tall (including the base rails), the TracRac SR keeps gear high enough for clearance but low enough for easy loading.

Very heavy duty ladder rack that does not "whistle" while you drive down the road. Easy install overall, and it is very easy to install and remove the racks as needed after the original install. At the time of purchase this was not available for my vehicle with a short 5.5' bed, but with very minor fabrication the rails for longer beds fit perfectly. I have recommended this rack to several people since purchased a year ago.
I am very happy with the quick processing and shipping of my TracRac from etrailer. The TracRac is well made and the instructions were good. It fit my 2015 Chevy Silverado 2500HD well. I was able to use it with my bakflip F1 tonneau cover but the seals rub against the rack rails. The only reason I did not rate it at 5 stars was that one of the rack arms had the center pipe in backwards. I had to spend 20 minutes removing it and turning it around to install correctly. It looks great on the truck and is very sturdy. The racks slide easily on the rails so I can adjust them to fit whatever I am carrying. It also allows me to slide the rear rack all the way back so I can open the bacflip tonneau cover without it hitting the rack arms.
In short: the sliding ladder rack is excellent.
Assembly: Plan on spending a good while assembling it, and make sure you have a decent torque wrench and ALSO a strong set of allen head sockets, so you don't round out cap screws. Be triple sure you have the top and bottom of the crossbars correct before attempting assembly.
Usability: other reviews have spoken to all of this, but for me: the carrying capacity mixed with ease of adjustment and removal. It also happens to look incredibly sexy, when installed on my 2016 Nissan Titan XD (and with the TracRac cantilever extension installed).
Well made product and pretty clear and straight forward install. This was installed on top of a Retrax Pro Bed Cover with stake bed cutouts and no Ram box for a 2018 Dodge Ram 2500.
Only negative comment was the kit was short 2 end bed rail caps.
Just to be clear, this is somewhat uncharted territory as there isn't any info I could find on the compatibility of the Trac Rac with the Retrax Pro bed cover. Worked out very well and no modifications were necessary otjer than cutting out the factory bed pocket cutouts in the RAM truck itself.
Highly recommend the combo!
etrailer.com is an outstanding company. I purchased a Thule system in January. Due to logistics (my fault) I tried to install the system in April. Three of the attachment arms were incorrect. I contacted Ashley of etrailer, the sales representative who sold me the system, who patiently listened and after receiving the needed photos and explanation, etrailer sent me a replacement system. The new system was installed and the truck is ready to go. Ashley's professionalism, communication skills, product knowledge were excellent. Ashley and etrailers' commitment to solving my issue expeditiously puts etrailer in a class by itself.
Very happy with the rack on my 2018 Silverado. I also have the Back flip hard top bed cover. I am able to open all but the very last position. I might still be able to adjust the rails and to get there but it hasn't been an issue. Used it to haul lumber and I made a bicycle rack that works with the racks and the bed cover down. Works great. Was not hard to install.
Past 20 years I've used Rack-It truck racks. They're solid steel, eventually rust and took two grown men (and an extra set of nuts) to remove them from the truck. Great racks. Just way more than what I need the older I get.
However I wanted something that could easily be removed (by myself), if needed, and was aluminum. I bought these, as well as the extension cantilever, and it serves my needs as a general contractor. It supports my 24' walk plank just fine. The only thing I have to be creative to transport is full length rebar. If I transported rebar all the time, this rack would not be my first choice.
At the time of my purchase, there was not a specific rack for my GMC AT4. So I simply measured the bed of the truck, bought one with a similar measurement, and modified the drilling holes to work.
Lastly, I didn't want a silver color rack on my black truck. While you could get the racks in black. You could not purchase a black cantilever. So I simply had all the pieces powder coated black.
Honestly, I get a lot of compliments on it. Because no one else has one like it.
I'm very happy with it. It's perfect for the occasional ladder, walk plank, or 16' piece of lumber. I've had it mounted for over a year now, with zero problems! I remove it weekly to go through the car wash, and throw it back on in 5 min or less when i get home.
We've been really happy with the Thule Sliding TracRac, and have made some unusual modifications. We wanted to mount it outside/around a camper shell, so we needed to mount the rails outboard of the truck bed (aluminum "shelves") and figure out how to make the crossbars longer (bought a third crossbar and connected extension sections by making three-holed t-slots nuts and using round aluminum tubes). None of this sanctioned by etrailer or Thule, of course. See photos, which also show an adaptor I made to mount a Thule square bar above the TracRac crossbar to use existing Thule accessories.
Couldn't be happier with the Rack, it went together and operates flawlessly. Dealing with e trailer was a snap, I was informed all the way through the buying process of shipping and arrival dates. Will absolutely buy shop again with e trailer.
I move a lot of material for work. This rack seems very well constructed, very easy to put together and install. Being able to adjust the racks and slide them completely out of the way was reasoning to purchase this exact unit. I also tow a gooseneck trailer and need full access to the bed of my truck. Great product that functions and looks nice on a black truck with chrome trim package.
Ordered this rack for my 2023 Ford F350 super duty long bed, even when being told it was on a 2-3 month backorder the sales team kept me updated throughout the whole process. I actually received this order 1 month ahead of original schedule and it fit perfectly on my truck. Everything lines up perfectly fine minimum tools where required and looks great.
I bought my first Thule TracRac in 2018 and loved it for its crisp style, robust integrity and ease of removal so in 2025 when I bought my next F-150 Lariat I bought the same Trac Rac again. It's a wonderful design. Pro-tip, get the BAK industries tonneau cover too, they fit together perfectly. Amazing!
This rack system has been excellent. Easy to install, convenient and easy to slide racks on and off, and built solid.
Great product. This is my 3rd and will buy a 4th for the next truck
Great rack. Easy to remove if necessary. Good for sandwiching tall stuff occasionally like a fridge or water heater. I recommend using a long 2x4 to evenly push and pull along the track if you don't have super long arms.
I bought this TracRac SR for a 2019 new gen GMC 1500 AT4 with a Lomax/WeatherTech tri-fold hard bed cover thinking I would still be able to open and close cover. I could not. The base rails overlapped the inside bed rail just enough to prevent opening the cover. The base rail itself measure 4" wide. When trying to size it up on truck I did notice that when mounted it looks like the rear base rail is larger than the truck bed rails and hangover the outside of the rails. Some people may or may not liked the fact that it does not follow the contour of the truck bed. I only opened the base rail box so can not comment on cross bars. The base rails were well made and very heavy duty. etrailor customer service is one of the best I have ever dealt with! They do a amazing job, the entire process of ordering to return was incredibly easy and they have a great knowledge of the products they sell.
DO NOT TRUST THE ADVICE GIVEN BY THE SO-CALLED EXPERTS AT ETRAILER. This rack WILL NOT fit the Carbon Pro Bed...I was told by 2 different "experts" that this rack would fit my 2023 Sierra w/the Carbon Pro Bed, since this rack mounted to the stakebed pockets and not to the underside of the bedrail. After receiving my order, I prepared to install the rails and cutout the front stakebed pocket covers which is required to do the install (also indicated by Kevin C. from ETrailer). As soon as I got to step 3 of the rail install instructions, I knew there was a problem. The instructions indicated there was a hole on the inside of the bed to secure the rear stakebed pocket adapter to. There is no hole or any other type of access to any of the stakebed pockets on the Carbon Pro Bed. So, now I have altered bedrails and have a rack that does not fit. It is completely irresponsible of the "experts" at Etrailer to provide information or direction that is not true or hasn't been confirmed.
Great product as it was promoted. Also good quality and strong. I’m using it to add to my rack.
Info for this part was:

That looks great on your truck! I am glad it has been working well for you. Where are you mainly taking that canoe out to?
