The Thule TracRac SR is made for serious hauling. With a 1,250-lb carrying capacity, you can move lumber, ladders, or double up on kayaks without stressing the system. The 69-1/2" crossbars give you plenty of width for oversized gear, and the 32-11/16" rack height keeps your cargo clear of the bed while leaving room underneath for everything else you need to bring along.
This rack slides along full-length T-track base rails, so you can position the uprights anywhere you need them. Push both together for tall cargo, or spread them apart for long materials. The quick-release knobs loosen and tighten by hand, letting you move or remove the uprights in seconds. When you’re not hauling, you can slide both sections together for unobstructed bed access and better aerodynamics.
Keeping gear in place is easy with the included tie-downs. Four heavy-duty aluminum load stops mount in the crossbar slots, sliding into position and locking down with a twist of a knob. Each stop has built-in loops for straps. Four side cleats attach to the uprights to anchor ropes or ratchets when you’re tying down wider or heavier cargo.
The rack and rails are made from 6000-series aluminum that’s strong and rustproof, yet lightweight enough that it doesn’t eat into your truck’s payload. A two-stage powder coat—an e-coat followed by a clear coat—adds extra protection against scratches and corrosion. That finish helps the rack hold up through harsh weather and heavy use without rusting or fading.
The TracRac SR mounts through the stake pockets, so you don’t have to drill into your bed rails. The wide base supports each upright securely without the need for extra bracing, and the entire setup stays stable even under full load. When you need to take it off, the rack lifts away cleanly without leaving holes or marks behind.

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.
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.
Great product as it was promoted. Also good quality and strong. I’m using it to add to my rack.
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!
Assembles easy, installs easy and seems to be quality materials.
Quality product and easy to assemble.
Love the flexibility and strength of this system. Carry building supplies all week then can remove for the weekend.
Excellent product and shipping! Order was shipped the day I ordered! Thank you for being a great company.
I like the rack and have owned 4 of them. My biggest complaint is that the finish comes off because they appear to be using a lower quality aluminum that the old style. My original one 15 years ago never did that.
Works as it should. Be sure to put never seize on all of the bolts. Stainless and aluminum don't mix.
Absolutely love it. Such an easy install, goes on and off in minutes, adaptable and adjustable, great weight capabilities and holds up the the elements well. It also takes seconds to slide the rear section up with the barrel adjusters to fit a motorcycle in the back. I've used it for ladders, construction materials, kayaks, and a place to hang my hammocks when my kids need a nap, ha. The retractable ratcheting straps (sold separately) are incredibly convenient. The only way this product could be made even better is if the vertical arms were height adjustable.
This is my second system. I've bought from you guys. It works flawlessly, as long as I keep the tracks waxed, I couldn't give you a high enough rating for our accident.These racks are
Great rack, use it to haul a couple kay aks.

Its still pretty handy. However the bolts that hold it in place are stainless and the rack is aluminum. It would be nice if the kit came with anti size compound. Most of the knobs have gotten stuck and Ive had to break them to get it apart. The finish has also gone bad and is pealing.
