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.

Rails work great once you get them installed. They allow me to haul my motorcycle and Kayays at the same time. Load the bike, slide the rack into position and you’re off. However, I had a very hard time getting them installed on my 2019 Silverado to sit perfectly parallel (1/8in) without loosing the functionality of my BAK revolver roll up tonneau cover. I had to buy

The TracRac rails arrived in three days for my new Sierra shortbed truck. I had the system on my previous Dodge longbed and transferred the sliding components to the new rails. The TracRac makes a extreme quality product here in the USA. With my first set up on the Dodge, I always got more compliments on the rack than I did on the truck. I'll see what happens this time. Also, over the years I have bought many products for my trucks, RV, etc from eTrailer and have always found them to be an outstanding company. Thanks
