Good morning Michael!

It looks like you are trying to determine if the Thule TracRac TracONE Ladder Rack w/ Cantilever # TH27000XT-EX will work on your vehicle that you entered into the system, being the 2025 GMC Sierra 1500. This specific part number I've linked will fit all bed sizes of that truck, and the kit does include the Cantilever add-on.

If you want to also check out the standard one, that would be # TH27000XT, so you can see there is a little price trade-off, but that extra bar over the roof is super handy!

What are you planning to haul on top of the system? Any kayaks or fun things, or is it more work-related like ladders and wood?

More for work unfortunately haha. I have a particular issue hauling long composite materials like AZEC.

@MichaelS Oh right on! Well I hope this helps you get those jobs done haha. Let me know if there's anything else I can help you out with or if you have questions about install etc. I know the kits above don't require drilling or anything like that which is nice.
