Features to know about

Haul Long Loads with Confidence: 1,250-lb Sliding Rack and 1,000-lb Cantilever Extension

This rack is built to handle serious work. It carries up to 1,250 lbs on the main system and another 1,000 lbs on the cantilever extension, so you can safely haul long boards, pipe, or ladders that stretch past the cab. The 32" over-the-cab extension adds extra support up front and keeps loads stable from end to end. When you’re done, the cantilever removes easily to convert the rack back to a more compact setup.

Thule TracRac SR cantilever extension attached to front crossbar extending over truck cab for added support of long cargo.

Get Full Bed Access Anytime: Sliding T-Track System

The T-track base rails let the uprights slide along the full length of your truck bed, so you can move them together when you need clear space for taller cargo. Quick-release knobs make it simple—loosen, slide, tighten, and you’re ready to roll. When you need to remove the rack altogether, it lifts out of the tracks without tools. This design gives you the flexibility to switch between work and open-bed hauling in minutes.

Stay Secure on the Road: Integrated Tie-Downs and Load Stops

Four heavy-duty aluminum load stops keep materials in place on the crossbars, and four side cleats on the uprights give you extra tie-down points for awkward or bulky gear. Each accessory slides and locks within the built-in slots on the crossbars, so you can position them exactly where you need them. It’s a straightforward setup that keeps ladders, lumber, or gear steady over rough roads.

Thule TracRac SR adjustable aluminum load stops mounted on crossbars with integrated tie-down loops for securing cargo.

Thule TracRac SR aluminum side cleats attached to uprights providing extra tie-down points for securing truck bed cargo.

Built to Last: Lightweight 6000-Series Aluminum with Dual Powder Coat Finish

The 6000-series aluminum construction is strong and rustproof, yet light enough that it doesn’t eat into your payload. A dual-stage powder coat adds even more protection—an e-coat to resist corrosion followed by a clear finish that guards against scratches. The elliptical crossbars cut wind drag, and airfoil trip strips keep the rack quiet on the highway.

No-Drill Install and Solid Stability: Stake-Pocket Mounting

Installation is simple—no drilling required. The base rails mount in the stake pockets, and the wide bases under each upright keep the rack steady without extra bracing. Once installed, you get a stable, aerodynamic system that’s ready for everything from daily work runs to weekend projects.

Great service and fast shipping and handling. Melissa T. Was very helpful finding answers to compatibility questions with other components. Site has great video reviews on their products. Definitely recommend them!… Best prices too.



by:

Great transaction and shipping was earl y.



by:

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.



by:

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.



by:

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.



by:

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.



by:

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.



by:

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.



by:

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.



by:

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.



by:

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.

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



by:

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.



by:

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

by:

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.



by:

I just received the Thule rack, so have not installed them yet. The service from etrailer was outstanding!



by:

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.



by:

Good quality material.

by:

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!



by:

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 +

3 times to get the right parts -
Special thank you to Tiffini S. from customer support center, she was very professional and helpfull.

  • Headache or Ladder Rack with Over Cab Storage for a 2006 Ford Super Duty
    We do have some options that are similar to what you are looking for your 2006 Ford Super Duty but, they are ladder racks and not headache racks.

And for a more economical option, you could take a look at the # EM07707. For a short bed the sliding ladder rack with extension is # TH43003XT-510EX. The other options...

The rack has an awesome 1250 lb capacity and has the ability for the uprights to slide back and forth for lots of load handling flexibility.

  • Tonneau Cover for 2016 Ford F-350 With Thule TracRac SR
    Hey Robert, welcome back! Since your Thule TracRac SR # TH43003XT-010EX mounts on top of the bed rails you need a tonneau cover that mounts inside the bed rails.

You can choose from the following: -Pace Edwards Switchblade Retractable Hard Tonneau Cover # 311-SWF7084 -BAKFlip MX4 Hard Tonneau Cover - Folding # BAK48311 -BAK Revolver X4s Hard Tonneau Cover - Roll Up # BAK87ZR -Access Vanish...

  • Can I Mount a Spare Tire on the Cantilever on the TracRac SR Ladder Rack?
    I went ahead and reached out to my tech at Thule, and he said that while there is technically enough weight capacity to mount a spare tire on the cantilever on the TracRac SR # TH43003XT-010EX, this is something they have not put through testing. They also said that any damage that occurs to the rack from this application could possibly void the warranty on the rack. With that being said, the safest option is to use an alternative method like the front-mounted tire carrier # 6715. Since...
