Hello Floyd,

Thanks for writing in.

Since your 2025 Chevy Trailblazer requires a battery disconnect while flat towing, I recommend the Roadmaster Battery Ace Battery Disconnect with Key Fobs # RM39ZT.

What I like about this system is that it takes the guesswork out of the battery disconnect procedure. Once installed, it provides a consistent way to disconnect the battery for towing and reconnect it when you're ready to drive. That helps eliminate the possibility of forgetting a step or not fully disconnecting or reconnecting the battery when using a manual method.

The Battery Ace installs at the battery and is operated with the included wireless key fobs. When you arrive at your destination, you simply reconnect the battery with the push of a button. Because the system is designed specifically for flat towing applications, you can be confident the vehicle's battery connection is properly restored so you're ready to start the Trailblazer and get back on the road.

Did you need any help with the other flat tow components you have picked out? I went ahead and attached a great help article on the "Must-Have Flat Towing Components," it is a great read if you are new to flat towing, or a great refresher for the seasoned flat tower.

@FloydB I don't think that I have ever received a reply from Roadmaster this quickly. This is what Tim had to say: "Kate, yes, the (768) can be used with the 2022-26 Trailblazer's with the 3 cylinders engine. Thanks, Tim" Their part number 768 is our part number # RM39ZT. I am now going to get our video updated, thanks for pointing that out.
