They sure do Lou. For just the 5-1/2' rails for a 2025 Ford F-150, you'll want the Base Rails for Thule TracRac SR Sliding Truck Bed Ladder Racks item # TH21508. This kit only includes the rails and mounting hardware. They measure 65.6" long x 4" wide x 1.9" tall.

If you're looking for the entire setup you'll need the Thule TracRac SR Sliding Truck Bed Ladder Rack item # TH43002XT-508. This is the one Thule recommends for the 2025 Ford F-150 with the 5-1/2" long bed.

Do you already have a TracRac SR Sliding Ladder Rack?

Hey Lou, how did things go with the Thule TracRac SR setup for your F-150’s 5.5-foot bed? Did the base rails fit the way you needed? Your experience could help others looking to build the same rack system.

@JerredH. The 5.5 foot base rails fit perfectly. I had to cut out the plastic cover above the front stake pockets of my new Ford F-150 to allow for the TracRac rubber inserts to drop into the pockets. For some reason the rear stake pockets have rectangular removeable tabs that pop out of the plastic coping with a screw driver but the front pockets don't. The TracRac components were all present and went together perfectly. After I cut the two holes out of the Ford plastic coping everything went smoothly.

@Lou That is great to hear! That's so weird about the different stake pockets. Glad you got it sorted out though.
