The Thule TracRac SR Sliding Truck Bed Ladder Rack w/ Cantilever can handle serious work and weekend hauls alike. It carries up to 1,250 lbs, with a cantilever extension that adds 32" of over-cab support so you can safely carry long materials like ladders, lumber, or pipes. The crossbars sit at full over-cab height, giving you the space to haul oversized gear without it hanging off the back. The cantilever also removes easily when you don’t need the extra reach.

The rack slides smoothly along unique T-track base rails mounted in your truck bed, so you can position the uprights anywhere along the rails. Move the crossbars close together for short gear or spread them out for long loads. When you’re not hauling, slide both uprights together at the front of the bed for full rear access and better aerodynamics. The integrated quick-release clamping knobs make adjustments easy—loosen, slide, and tighten back down, no tools needed.


Built from 6000-series aluminum, this rack is both strong and lightweight. The material won’t rust, and the dual-stage powder coat—an e-coat followed by a clear coat—adds extra protection against scratches and corrosion. That means you get the strength of a heavy-duty system without loading down your truck or worrying about rust eating into it over time. The wide base design adds stability, so it holds steady even under full load.
The elliptical crossbars are shaped to cut through the wind instead of catching it, keeping the ride quiet even at highway speeds. Built-in airfoil trip strips stop air from whistling through the slots, so you don’t get that high-pitch noise that some racks make. You can focus on the drive instead of the wind noise behind you.
Eight tie-downs come standard—four load stops that slide in the crossbar tracks and four side cleats that mount to the uprights. The load stops lock in place to keep ladders, lumber, or pipes from shifting, while the cleats give you extra anchor points for straps. Together they make it easy to tie down just about anything quickly and securely.


Installation is simple with the no-drill design. The base rails mount right into the stake pockets of your truck bed, so you don’t have to make any permanent changes. Once mounted, you’ve got a rock-solid foundation for every job or adventure ahead.

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.
Delivery in three days. Three boxes. Exactly what I wanted to carry our Kayaks and ladders across the country to our new home.
Just installed this rack by myself. Fairly easy and took less then 2 hours to do. Looks really great on the truck
