This item is a must to go along with the rack I bought. It not only look good on my truck but it can handle lengthy items. I am totally satisfied with my purchase.

Robert G.


Love it, it works great for me and looks awesome on my truck.


Haven’t assembled yet do to damaged parts, waited a while for this piece and planned a project around the date of arrival.


replacing an my older track rack system has lasted 20 years. now upgrade to the new model wish they didn't change the bed railing to only 2 sliding rails instead of 3. but it will work jest fine. the service and the fast shipping. awesome customer service thank you guys.


I've used the extension now for a year. Its very nice looking and distinguishable (people know my truck by seeing the ladder rack). It works great for hauling around stiff items like extension ladders. It also does an okay job of protecting the cab roof when hauling around flexible items like 20' framing lumber. It's not as tough as I thought it would be, I think the 1000 lb rating is a little generous; it's better rated at under 600lbs.


Garbage, sits a full inch higher than the rack it's bolted to. Designed by fools. Unusable trash.

It is normal for the cantilever extension to be 1 inch higher than the bed racks. It is so that once the system is loaded it will level out to the height of your bed racks.


Only had a few weeks to check it out but so far it’s very sturdy and I’m very impressed with the product.


Definitely made a big difference for us carrying longer items, but it also increase road noise significantly.


The cantilever extension works great. Heavy duty, good quality and its aluminum (no rust). I have a GMC 2500HD and there is good clearance over the crew cab. I had to purchase this separately from the T-RAC Pro 2, which required replacement of some of the bolts on the T-RAC Pro, resulting in left-over parts and fittings. Thule quality + spare assembly parts = $$$, so I deduct a star.


Looks great and fits well. The only thing I notice is the cantilever sits almost an inch higher than the other uprights so boards need to be sprung down at the forward upright to make them fully secure.


My truck has dealer installed Trac-Rac - nobody could tell me the exact model number though. The installed straightforward but breaking open the installed cross-bar took a little grunt on the screws as they have locktite on them. Once apart fitup went great but the alignment of the 3 cross-bars horizontally had the added extension cross-bar higher by about the thickness of the cross-bar. I pulled off the side extensions and flipped them `upside down' crossing sides. I filed the little indents and drilled the now bottom of the brace to receive the corner struts. Put them on and now the cross-bar is slightly lower. This is not a problem because I installed a wear strip over the top to makeup the slight lower elevation. Everything looks perfect, no one but me will know. But it did take about 3 hrs vs. an hour or so as purported. Thank you.


I own a gutter company and work with this company all the time for my truck supplies and set up. We purchase the Trac-Rac system at least 2x's a year from them. The system is solid and the cantilever is vital when dealing with ladders longer than 28'. Every single employee I deal with is polite and professional. Shipments get delayed due to shortages, packages get damaged due to shipping, but this company for the last 6 years has always done right by us. Not sure what we love more the products or the service. Thanks again to Stacey and the rest of the great staff at etrailer.


After adding the extension to my Thule rack, I noticed a half inch lower
Height of the middle cross bar compared to the rear cross bar on my Silverado.


The cantilever worked very well and I am very happy with it. If it was even longer to fit more over the top of the truck it would be even better.


Working great. Hauling ladders and lumber longer than 8ft.



This truck rack is very versitle. I like the adjustability. Works great after a year of use. Very durable.


Works great, takes all the weight you need it to and helps stabilize long boards and vinyl siding from hitting the roof of your truck. The only thing that would make it better would be if they offered this model in black


Fast shipping and thorough service. The extension performs as it should and fits perfectly.


Perfect addition to my work truck


sturdy product, well engineered & rugge d.


Arrived very quickly and in good shape.



excellent. Delivery is extremely prompt. Very professional company.


Great price and good quality

  • Will T-Rac Pro2 Truck Bed Ladder Rack with Cantilever Fit Over Cab on 2019 Ram 3500
    The bottom of the crossbar for both the T-Rac Pro2 Truck Bed Ladder Rack # TH37003XT and the Cantilever Extension # TH24002XT will be just over 27-3/4" so as long as the cab of your 2019 Ram 3500 doesn't sit more than 27-3/4" above the rails on your bed you're good to go!

  • Will the Thule Cantilever work for the Older TracRac Systems
    The add on Cantilever Extension for Thule TracRac SR, G2, and T-Rac Pro2 Ladder Racks part # TH24002XT or the Cantilever Extension for Thule TracRac TracONE Ladder Racks part # TH24001XT will work with the older TracRac. You just have to determine what model you have. Look for a model or serial number on the rack itself. If you have trouble identifying it please let me know what info you can find and I'll be happy to do what I can to help out.

  • Can Cantilever Extension be Added to TracRac SR Ladder Rack
    Yes, the over-the-cab cantilever is available separately as part # TH24002XT. If you wanted to add this to an SR TracRac ladder rack this is what you would need. This will come what you'd need to add that third bar out in front above your truck cab.

  • Can Additional Crossbar Attach to Thule TracONE Ladder Rack Load Bar
    Sounds like you are looking for like a cantilever extension to mount an additional crossbar in front of your TracOne ladder rack. For that you'd just need the part # TH24002XT which attaches to the current load bar and gives you an additional one mounted out in front of it.

  • How to Add an Over-The-Cab Extension to a TracRac Ladder Rack
    An over-the-cab extension is not a universal piece and will be dependent on the type of ladder rack you have. If you have a TracRac SR, G2, or T-Rac Pro2 then you can add the over-the-cab extension using part # TH24002XT. If you have a TracRac TracONE then you can add the over-the-cab extension using part # TH24001XT. Unfortunately, we only carry over-the-cab extensions for TracRac ladder racks at this time.

  • Will Thule TracRac Toolbox Mount Kit Work Work with Old Style TracRac Rails on 2019 Ram 2500
    Unfortunately, my contact at Thule confirmed that the TracRac Toolbox Mount Kit # TH25200, cannot be retrofitted to the old style TracRac rails. The correct rails for your 2019 Ram 2500 with the 6-1/2 Foot Bed (without RamBox) are part # TH21501. However, these rails are only going to work with the current Thule Track Rack SR Sliding Ladder Rack # TH43003XT, so the only solution that will allow you to keep the toolbox on your truck is to replace the old system with the new one.

  • Is the Cantilever Extension Compatible with the TracRac Truck Cap Ladder Rack for 2018 Ford F-150
    For your 2018 Ford F-150 with 5.5 foot bed the Thule TracRac CapRac Ladder Rack for Camper Shell/Truck Cap # TH29200XT is what is confirmed to fit the cap on your truck. The cantilever like # TH24002XT although it would fit the crossbar of the system is not recommended to be used because the torque on the feet and mounting hardware of that system are not rated for the extra 24 lb extension and any weight you would add to it. The cantilever system is designed only to be used with the...

  • Availability of TracRac SR Sliding Ladder Rack for a 2014 Ford F-150 5-1/2 foot Bed
    We do have the TracRac SR that will fit your 2014 Ford F-150 with a 5-1/2 foot bed, for that you will want part # TH43002XT-508. You can add the over-the-cab extension later with part # TH24002XT. As for the fold up tonneau cover that you have already installed on your F-150, it really depends on the style. If it is a soft tonneau cover that mounts inside the bed rails then it will most likely fit, but if it is one of the hard fold up covers then the rails on the TracRac SR overhang the...

  • Will The Cantiliever Extension For Thule T-Rac Ladder Rack Clear The Roof Of 2018 F350?
    I have not heard of any clearance issues when using the Cantilever Extension # TH24002XT and T-Rac Pro2 Truck Bed Ladder Rack # TH37003XT on a 2018 Ford F350, but you can take a measurement just to be sure. Measure from the truck bed rail to the top of the cab; if this is less than 27-3/4" then the cantilever extension will clear the roof of your truck. There is a bumper on the bottom of the extension so that it will not scratch your roof if it ever happened to make contact during installation...

  • Can A Cantilever From A New TracRac Be Added To An Older Model Of TracRac?
    Hello Pat. Do you happen to know exactly what model your older TracRac system is? Or perhaps when it was made? Knowing that will help narrow down exactly what parts are compatible and what your options will be. If the cantilever extension you were given is for the new TracRac like part # TH24002XT, it is not going to work with certain older models. For example, the # TH24002XT will work with the following models: - Thule TracONE ladder racks manufacturer from 2018 to present - Thule...

  • Recommended Ladder Rack For A 2014 Toyota Tundra With Deck Rail System
    Hi Maurice, Thule offers the TracRac SR which mounts in the stake pockets so that you still have the cantilever and don't have to remove your deck rail system. If your Tundra doesn't have the stake pockets then the installation will require drilling into the bedrails. The design of this ladder rack will also allow you to install tonneau cover as long as it sits inside the bedrails and doesn't overlap the top of the bedrails. 6-1/2' bed # TH43002XT-610EX 8' bed # TH43002XT-011EX If...

  • Recommended TracRac Cantilever Extension Over Cab for TracONE Systems
    Thanks for your kind words. The TracRac Cantilever Extension # TH24001XT is the correct fit for your TracONE ladder rack on your 2010 Dodge Ram Big Horn 1500 with 6-1/2 foot bed. This will give you an extra 32 inches of length over your cab to support your load. You may want to consider the Tie-Down Loops for TracRac Ladder Rack Crossbars # TAPI-11019 to give you the addition tie-down locations as well. The # TH24002XT is not a fit for TracONE systems.

  • Can the Thule Cantilever Be Added to TracRac And Used to Carry a Cargo Basket
    I spoke with my contact over at Thule and they say that using a cargo basket with the Thule Cantilever # TH24002XT and Thule TracRac SR # TH43002XT-780 is not typically something that they've seen and have not tested this application use on this product. Just because they haven't seen it, doesn't mean that it can't be done, but it was noted that the Cantilever bar was not designed to carry an extremely heavy load-it was simply designed to help spread out the weight on longer loads.

  • Will the Thule TracRac SR Sliding Truck Ladder Rack Fit My 2021 Toyota Tacoma (5-Ft. Bed)?
    I have a solution for you. Unfortuantely, there are no models of the Thule TracRac SR Sliding Truck Bed Ladder Rack w/ Cantilever that will fit your 2021 Toyota Tacoma (5ft. bed with or without rail deck system). However, the next best solution as far as weight capacity and functionality is the T-Rac Pro2 Ladder Rack for Toyota Tacoma - Fixed Mount # TH37005XT. As far as fitment, the T-Rac Pro2 will fit 5-foot beds on your 2021 Toyota Tacoma with or without the rail deck system. The T-Rac...

  • Thule Cantilever Extension Is Sitting 1" Higher Than The Ladder Rack Crossbars
    That is completely normal. Thule states that the Cantilever Extension # TH24002XT will sit about 1.5" to 2" higher than the bed racks. Once the rack system is properly loaded, it will level out with the height of the bed racks. If you are not putting much weight on the extension then it is likely just not enough weight to push the bar down level with the rest of the ladder rack. As long as you are not putting over 1,000lbs directly on the cantilever extension then you will be fine.
