TracRac Base Rails


TracRac SR Sliding Rack Base Rails

The TracRac base rails provide the foundation for this unique, customizable system. No-drill, stake-pocket installation yields securely mounted rails that sit atop your factory side rails. Each rail has 2 tracks for maximum adjustability.


TracRac Sliding Rack

Because the rack section at the front of your truck bed mounts to a different T-track than the one in the rear, the sections can be moved so that they are right next to each other. The result is unobstructed access to your truck bed and improved aerodynamics when you are not using the rack.


TracRac offers accessories that are designed to mount in these tracks. Base rail tie-downs (sold separately) give you additional cargo-management options. These rustproof, aluminum tie-downs slide across the rails for optimal placement and are secured in place with the turn of a knob.


Cantilever Over-the-Cab Extension


TracRac Cantilever Over-the-Cab Extension

Included with your TracRac system is the cantilever extension, which attaches to the front crossbar to provide 32" of additional length over the cab of your vehicle. With this extension piece mounted you can carry long loads safely and easily. The crossbar of the cantilever extension is constructed in the same fashion as the other TracRac crossbars so that you get the same sturdy, aerodynamic styling throughout.


TracRac Slotted Crossbars

The sturdy aluminum crossbars on all TracRac truck racks feature integrated slots for mounting and easily adjusting accessories, such as the included load stops. These slots appear on both the top and bottom of the bars for the ultimate in mounting versatility. Like the pieces that mount in the base rails, these accessories also have quick-release knobs that let you loosen and tighten them with a mere twist of a knob so that they can be positioned as needed along the bars.


A built-in trip strip at the front of each crossbar shields the slots from wind, maintaining the aerodynamic quality of the bars and preventing that annoying whistle you often find with slotted bars.


Included Tie-Downs


TracRac Load Stop Accessories

Included with your TracRac SR are 8 tie-down accessories. The 4 load stops are designed to mount in the slots of the crossbars and slide along them for quick, easy adjustment. These bookend-style pieces help to hold ladders and lumber in place on the crossbars. They also have built-in loops for securing tie-down straps.


TracRac ARC Side Cleats

The 4 cleats attach at any of the provided mounting points along the outsides of the upright supports so that you can tie down items that require additional anchoring or that sit in your truck bed.


Sturdy, Rustproof Construction

The TracRac base rails and rack system, as well as most TracRac accessories, are constructed of durable, lightweight aluminum. Because aluminum is lighter than steel - the material most often used for truck racks - only a small percentage of your truck's cargo capacity is taken up by the rack itself, enabling you to pack on more weight than you could with a steel system.


Even though aluminum is already rustproof in itself, TracRac has taken the extra step of adding a dual powder coat finish to further protect your rack. The electrostatic powder coat (e-coat) clings to the metal surface better than traditional paint finishes for a more durable covering. The second coat is a clear finish that adds extra shine and protection from scuffs and scratches.

  • Over Cab Ladder Rack and Tonneau Cover for 2019 Ram 2500 Long Bed
    Since your ladder rack wraps around the bed rails to attach there won't be a way to also install a tonneau cover as that would interfere. Only solution would be a ladder rack that installs through the top of the stake pockets. Let me know if that's something you'd consider as we have options for that.

  • Is there a Sliding Ladder Rack for a 2024 Ford F-250 w/ the 8 Foot Bed?
    Yes, there is! There are actually two options to add a sliding ladder rack to your 2024 Ford F-250 with the longer 8' bed. They're both made by Thule, attach to the stake pockets of your F-250, and have a 1,250 lbs capacity. The main difference between the two are one has a cantilever section that extends over the top of your roof. I have listed both options below: With Cantilever - Thule TracRac SR Sliding Truck Bed Ladder Rack w/ Cantilever item # TH43003XT-000EX Without Cantilever...

  • Can I Use a Thule TracRac SR Sliding Truck Bed Ladder Rack on a 2015 Ram 3500 w/ a 8 Foot Bed?
    Yes, you can so long as the tonneau cover leaves your stake pockets exposed and you do not have ramboxes. The Thule TracRac SR Sliding Truck Bed Ladder Rack w/ Cantilever item # TH43003XT-000EX is confirmed to fit the 2015 Ram 3500 with a 8' bed. However, it needs to be able to access the stake pockets to install.

  • Ladder Rack & Tonneau Cover Compatible With 2018 Ford F-450 Super Duty
    While we have an option for a ladder rack and tonneau cover that fits your 2018 Ford F-450, there isn't a tonneau cover that will work with a rack that mounts inside the bed rail. The reason for that is all tonneau covers either use or sit up against the bed rail when installed, so there would be interference with a rack. The best option is going to be a ladder rack that mounts on top of your F-450's bed rail, and a tonneau that mounts inside the rail. For the rack, what you will need...

  • What Do I Need To Install Pace Edwards Contractor Rig Rack On My 2022 Ram 2500 With 8 Truck Bed
    The Pace Edwards Contractor Rig Rack Truck Bed Ladder Rack - Aluminum, part # 311-CR4005, is designed to fit a Pace Edwards retractable tonneau cover with t slots, not the truck itself. The Pace Edwards Switchblade Retractable Hard Tonneau Cover - Aluminum and Vinyl - Black, part # 311-SWD7936, has t slots and is compatible with your 2022 Ram 2500.

    Yes, it is. We have four different options for sliding ladder racks that fit the 2024 Ram 2500. Two are for the 8' bed length and two are for the 6-1/2' bed lengths without Ramboxes. There are also different options for the ladder racks that have the cantilever section that hangs over the cab.

  • 2018 Ford F-250 Super Duty Thule TracRac SR with Cantilever Fitment
    The correct Thule TracRac SR Sliding Truck Bed Ladder Rack w/ Cantilever for your 2018 Ford F-250 Super Duty is part # TH43003XT-785EX if you have the 6-3/4' bed or part # TH43003XT-000EX if you have the 8' bed. These are custom-fit options so modification won't be necessary. Please note the bed rail to cab height difference on your truck is less than it is with other models so you're going to have 2-1/16" from the bottom of the cantilever extension to the top of your truck cab at the...

  • Can The Pace Edwards Contractor Rig Rack Truck Bed Ladder Rack Be Used Without The Tonneau Cover
    The Pace Edwards Contractor Rig Rack Truck Bed Ladder Rack # 311-CR6008 is designed to slide into the T-Tracks found in explorer series rails so it would require a tonneau cover. It is also not a fit for your 2022 Ford F-350 though so the closest option to this would be the Thule TracRac SR Sliding Truck Bed Ladder Rack w/ Cantilever # TH43003XT-000EX. This ladder rack has a 1,250lb capacity and comes with a cantilever to provide extra storage space above the cab of your truck. The towers...

  • TracRac SR Sliding Truck Bed Ladder Rack Fit for 2018 Ram 2500 Truck
    I reached out to my contact at TracRac and they said that the TracRac SR Sliding Truck Bed Ladder Rack - 1,250 lbs # TH43003XT-501 is a carry-over for the 2018 model with 6-1/2 foot bed as long as you don't have the Rambox storage. If you have the 8 foot bed, you will want the # TH43003XT-000. If you want the over-the-cab extension with the rack, then you will want the # TH43003XT-000EX or the # TH43003XT-501EX. This extends the rack over the cab of your Ram truck.

  • Will TruXedo Lo Pro Fit with TracRac SR on 2021 Ford F-350 Super Duty with 8' Bed
    Yes, the Thule TracRac SR # TH43003XT-000EX will work just fine with the TruXedo Lo Pro Soft Roll-up Tonneau Cover # TX579601 for your 2021 Ford F-350 Super Duty with an 8' bed. Since the cover mounts inside the bed and the TracRac SR rails sit on top of the bed rails you won't have any issues with fitment.

  • Best Roof Rack For a 2024 Ford F-350 Dually Long Bed Truck
    I recommend using the Thule TracRac SR Sliding Truck Bed Ladder Rack # TH43003XT-000EX on your 2024 Ford F-350. I like this rack as the rails mount onto your bed rails and allow you the ability to easily reposition the uprights for large loads. It also makes it easy to remove from your truck if you don't always need the rack. The front upright has a cantilever positioned 32" forward which will help protect the roof of your truck when carrying extra long objects.

  • TracRac Ladder Rack Recommendation for a 2014 GMC Sierra 1500 with Over Cab Extension
    The TracRac TracOne Rack part # TH27000XT-EX that you referenced can't have the over the cab extension installed on it. I checked with TracRac to confirm this. The only way to install that style of rack on your vehicle would be to replace what you have with the # TH43003XT-000EX if you have an 8 foot bed, part # TH43002XT-508EX if you have a 5-1/2 foot bed.

    Thule does make a TracRac SR sliding ladder rack with cantilever for the 2020 Ford F-150. The exact part needed will depend on your bed length. For a 5-1/2 foot bed, use # TH43002XT-508EX. For the 6-1/2 foot bed, use # TH43002XT-501EX or # TH43003XT-000EX for the long bed model. All three include the cantilever, the rack and slides as well as all necessary installation hardware.

    Since your TracRac SR Sliding Ladder Rack model # TH43003XT-000EX uses bed-rail-mounted tracks you can use a hard tonneau cover that installs inside the bed rails. This avoids any interference between the mounting requirements for these two aftermarket products. On the linked page you can view all hard tonneau covers that mount inside the rails. The best choice for use along with the SR rack is the BAK Revolver X2 cover # BAK39331 which is shown in the linked video. This cover is USA-made,...
