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.

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!
