Hey Charles! What kind of 5th wheel do you have? For your 2025 GMC 2500 AT4 I recommend the Pacbrake Alpha HD Air Bag Suspension Kit # PB56SV. These are high quality air bags (like Firestone) and this particular kit comes with the 2" spacer for AT4 models. The 5,000 lb load leveling capacity should be more than enough for your 5th wheel and they also feature a limited lifetime warranty.
I also recommend adding an air compressor like the Pacbrake Single Channel Wireless Air Spring Controls w/ Compressor # PB99MV. This will allow you to control the air pressure no matter where you take your 5th wheel from the cab of your truck. It is a wireless system so it works via the app on your phone.
