Question:
Can you install a tee and hook the airlines together so you only have to air one fitting and both bags will have equal pressure?

Hi Larry!
You can definitely set up the Firestone Ride-Rite Red Label Extreme Duty Air Helper Springs - Rear Axle # F2709 to use one fill port on your 2025 GMC Sierra 2500. People typically want to be able to adjust each bag separately with the Red Label kits, so you will need to add the Firestone Union Tee for 1/4" Tubing # F3025-1 to your order and you are good to go. Just keep the other inflation valve as a spare in case you ever need it.
What are you towing with your Sierra?

Hi Larry, Did you get a chance to set up the air helper springs on your Sierra using the union tee? I'm curious to know how it worked out for you, as it could help others looking to do the same setup.
