Customized base rails are specially designed to fit your vehicle. Required to mount your Thule TracRac SR truck rack, these base rails feature 2 separate tracks so that you can easily adjust the rack along the full length of your bed.
Features:
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.
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.

4 years later.....I purchased the base rails along with the whole SR sliding bed system and the cantilevered extension in 2021 and I can't say I've really had any complains. the fact you can move everything around to suit you needs is amazing, need to transport a bunch of 2x12x26s; no problem. need to load a fridge or a motorcycle? no problem. Strongly recommend. I should note that if you don't have tools or aren't mechanically inclined you should have a shop install it. I personally had no issues, installed it in my driveway and haven't looked back.
great product and system. Allows you not to have the racks permanently on vehicle
