The Thule TracRac SR Sliding Truck Bed Ladder Rack w/ Cantilever can handle serious work and weekend loads. With a 1,250-lb carrying capacity and a 1,000-lb rated cantilever extension, it keeps long items like pipes or lumber supported well beyond the cab. The cantilever adds 32" of extra space up front, so heavy materials or gear won’t flex or sag over the bed. Its 69-1/2" crossbars give you plenty of width for wide cargo, while the over-cab height design clears the roof for safer hauling.

The rack slides smoothly along unique T-track base rails that run the full length of the bed. You can move the uprights together for compact storage or slide them apart for hauling long gear. When it’s time to load something tall, just bring both rack sections forward and clear the rear of the bed. The integrated clamping knobs make repositioning quick—loosen, slide, and tighten to lock it down. This sliding setup gives you more flexibility than fixed racks without compromising strength.

Made from strong yet lightweight 6000-series aluminum, this rack adds little weight to your truck but delivers exceptional durability. Aluminum won’t rust, and the dual-stage powder coat finish—an e-coat followed by a clear coat—protects it even more from scratches and corrosion. That means it stays tough through rough weather and heavy use without losing strength or finish.
Each elliptical crossbar is shaped to cut through wind and reduce drag. Built-in airfoil trip strips stop that common whistle found on slotted bars, making highway drives quieter. Inside, the crossbars feature an internal web structure that increases rigidity without adding bulk. The result is a rack that’s both strong and streamlined.
The TracRac SR installs using no-drill stake-pocket mounts, so there’s no need to modify your truck bed. The wide base of each upright spreads out the load for extra stability, eliminating the need for extra bracing. Included load stops and side cleats slide and lock anywhere along the crossbars or uprights, giving you multiple tie-down points to keep ladders, lumber, and tools locked in place.


Ratings & Reviews
Its an excellent rack system. The only complaint I have that keeps it from 5 stars is the knobs to lock the slides in place are difficult to use due to the shape, I'd prefer a wind nut style for leverage and the hardware corroded substantially within 6 months and everything had to be removed and cleaned and reinstalled with antisieze to keep everything operational. Other than that it is an awesome set up and gets the job done.
Shipping was quick As described Easy to assemble. Wish the kit had one set of directions so I wouldn't have had to take the front rack apart after the fact. The final bolts for the canteleaver seem to be a damage/ scratch hazard.
Looks pretty slick though.
Does the trick. Benefits from occasional tightening and adjustment. The sliding vertical brackets on top are finicky. Very handy attachment points for bungees and straps.
Product is great and installed easily once I figured out that for my Ram 1500 Laramie, the pocket stakes are too big for the rubber blocks and won't work and I did have to drill thru the plastic molding. Once I figured out the stake holes wouldn't work I looked at the drawing again and the holes where Tundra is listed gave me the idea to try those. Those holes worked on the Ram and I ended up drilling out the "spikes" that hold the molding onto the sheet metal. No drilling thru the sheet metal was required, only the plastic.
Maybe I missed an install video for the Ram, it would have made the install much quicker and I wouldn't have to buy covers for my now cut out front stake pocket holes which weren't covered by the rails as I hoped they would.
I haven't installed the cantilever as I don't need it yet.
The rack system is very well put together. I only had a couple of issues with the instalation.
There wasn't any directions with the base rails, so it took a bit to figure out how it went together and what holes to use for my truck.
The canteilever kit, The top bolt that holds the cross bar should be a button screw and square nut, not a square head bolt and nut. with the square head bolt and nut it could interfere with a long load since it sticks up and could catch on anything being loaded . All and all a nice rack.
I got this type of rack hoping that I could slide the rear post forward as to not interfere with my 5th wheel when towing it.
That part is yet to be dedurmined.
I purchased the front rack with the cantilever over hang, toolbox track kit and rear rack and locking knobs.
Very happy with the final product.
Thanks.
This is an awesome system, and in my opinion, the best option to pair with the Retrax ProMX bed cover. The sliding rails for adjustable distance is awesome. Can't beat the versatility of this rack, and after adding additional load stops for cantilever rail, bolt on ratchet straps, and base rail tie down points (which will actually allow me to haul things on top of my bed cover, which is rated to carry 500lbs) this system completely changes my ability to haul whatever I need in my truck.
Great product, super easy install. No drill application is wonderful and fast so I can put it to work to pay for itself, less than 2 hr installation.
I ordered the TracRac SR (sliding rack) for my 2019 Ram 3500. It took a while to get here, probably due to the current situation weall in. It came in 3 boxes on 2 days. (Just so you know what you'll be looking for) everything was packaged very secure in the boxes. I order the Cantilever with mine, so I had to swap out a couple parts. No big deal. Everything was explained in the instructions. It took me about 3 hours to install. The hardest part was getting the bed rails to align. I got them within 1/16th of an inch. Good enough.
The rack is a great addition to the truck. I stepped down from an 8ft bed to this 6ft 4in bed. So this was a necessity. The rack is solid. I'll be putting it to work right away
The product was super easy to install and it’s very stout even though it’s technically a ladder rack. I am in the water well business and use it for hauling my pipe galvanized, PVC you name it. I did have a little issue with two of the uprights but nothing that couldn’t stop me from installing it, I reached out to the support team and Joshua B was extremely helpful. They sent out replacement parts with a few days to make it right with me. I greatly appreciate all of their help.
The TH43002XT-781EX installed onto my 2016 GMC 2500 HD Sierra 6-1/2 bed Denali pickup truck without drilling any holes. Total install time including the cantilever took about 2 1/2 hours with two people. The tools we used included a wide range of metric hex keys, a crescent and some metric open-endeds.
The base rails mounted to the bed rails using a threaded aluminum insert for the rear stake pockets (which align with a thru-hole already present in the bed) and an expanding rubber bushing for the front stake pockets (since the front pockets don't have a thru-hole). Evidently some pickup rails cant to one side or another so the base rail install kit includes shims but my truck did not require them.
Once installed the rails are rock solid and subsequently the racks are also rock solid. The cantilever comes with replacement saddles that mount up to the rack with a total of 12 bolts making the ensemble nearly missile proof. Almost all bolts are pre-treated with thread locker.
My truck already has knobby tires so I did not notice any particular additional wind noise.
My plan for the TracRac is to attach a custom mounted Rhino-Rack, which we'll be doing ourselves.
I like this product because the fitment on etrailer was reliable and I did not have to drill any holes or use any special tools. The rack is also ridiculously heavy duty, which is more than up to the job of holding the Rhino-Rack I'm going to custom fit to it. We'll be doing some off-roading so this heavy equipment gives me a lot of confidence.
Thule always makes great products and I am delighted with the TracRac and I'm very happy with etrailer's site.
Pretty good ladder rack. I like having the ability to slide the racks if needed. The install is doable. If you are installing the cantilever, make sure you swap out the top mount before assembling the top bar. The legs come pre-assembled with the regular top mount from the factory. The regular top mount has to be removed and the cantilever top mount installed to assemble the cantilever part of the ladder rack. Also, the bolts that hold the top mount on have loctite on them from the factory and are really hard to remove. I ended up stripping the bolts out. etrailer was very helpful and sent me a replacement hardware kit with all the bolts needed to finish the install. Between the directions provided and a few YouTube videos, the install was pretty straightforward. I am very happy with the product overall.
Great system
Fast shipping very res ponsive
Love it! kayaks, ladders anything too long to fit in a five and three-quarter bed go on the ladder rack. It slides out of the way when I have big bulky things like refrigerator to put in the back of the truck. And I got to keep the tonneau cover that came with the truck.
I just received the Thule rack, so have not installed them yet. The service from etrailer was outstanding!
I bought these for my 2018 Ford F 150 5.5foot bed.
These are definitely one of the more expensive ladder racks you can buy but totally worth it. Very high quality and easy to install. I bought these for the ease of removal.
I use etrailer.com for all my vehicle needs.
Good quality material.
Fast shippi ng
The movable rack let's it be mostly out of the way when not in use without removing from truck. The high load rating plus cantilever let's me haul long semi flexible objects (the flexing puts a significant strain on the rack)even with a shorter bed.
The ladder rack is awesome +
It took 3 times to get the right parts -
Special thank you to Tiffini S. from customer support center, she was very professional and helpfull.
Customer service was excellent. With Tiffini's help and Georges and Carol's updates this was a smooth purchase. Tiffini's help in sending links to me with the correct part choices for my truck was extremely valuable and saved me a lot of time.
The parts came in on time and Lauren stayed in contact with me throughout the whole process. She is incredible at what she does and my racks look great and function perfectly for my construction needs! Thanks etrailer!
