Thule TracRac Base Rails

These unique base rails provide the foundation for Thule TracRac's customizable truck bed ladder rack 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.


Thule 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.


Thule 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 along the rails for optimal placement and are secured in place with the turn of a knob.

  • TracRac Sliding Ladder Rack With Tonneau Cover on 2018 Chevy Silverado
    If your cover mounts to the inside of the bed rails and not on top it shouldn't interfere, however I have not tested this exact combination so I can't confirm if it will work. The main thing that will cause any kind of interference is if the cover is mounted to the outside, or top of the bed rails. The Thule TracRac does use base rails that mount to the truck's bed rails, and provides a T-track or channel for the uprights to slide back and fourth on. The complete system is rated for...

  • Sliding Ladder Rack and Tonneau Cover that Fits 2016 Ram 1500 5-1/2 ft Bed
    For your 2016 Ram 1500 Rebel with a 5-1/2 foot bed you'd need to go with a different tonneau setup on your truck to install a Thule TracRac sliding ladder rack since your Switchblade covers the stake pocket openings.

    The base rails on the Thule TracRac SR # TH43002XT-508 install via the stake pockets with a bolt, rubber block and t-plate.
