Question:
I’m having a hard time properly spacing the rails #21781 on my 2020 Silverado. Is there a difference between the rails? Also which hole spacing should I be using?

Expert Reply:
There are different base rails for the TracRac SR for your 2020 Chevy Silverado 1500, depending on the size of your truck's bed:
- 5'8" Bed: Base Rails for Thule TracRac SR Sliding Truck Bed Ladder Racks # TH21782
- 6'6" Bed: Base Rails for Thule TracRac SR Sliding Truck Bed Ladder Racks # TH21781
As far as hole spacing, I looked at the directions, and there was not specific measurements for spacing; they simply said to "align base rail holes with vehicle stake pockets."
