Question:

My 2025 Tundra carries a bed rack, rooftop tent, tools, and sometimes a utility trailer. not usually all at the same time. Will this wireless Firestone kit help keep things level with mixed weight?

Hey Trevor, it definitely will! The Firestone Air Suspension Upgrade Kit # F59XV lets you tune the rear suspension to match whatever combo you’re hauling. Since the kit adjusts from 5–100 psi, you can keep it soft when you’re just daily driving (5–10 psi), then bring it up when the bed load and tongue load stack together so that the truck and trailer stay level and safe.

And because it’s wireless, you don’t need to run lines into the cab, which keeps the install clean on a nice newer truck like your 2025 Tundra.

How much weight do you think your bed setup adds? Do you have a rear anti-sway bar yet? I believe those trucks have one from the factory, but it never hurts to upgrade like the # HE29TR for better towing experience and to reduce side to side movement.
