Hey Antonio.

Unfortunately, the Firestone Ride-Rite # F2609 won't fit your 2026 GMC Sierra 1500 with the 3.0L Duramax diesel.
However, we have two other potential options:

-RoadActive Suspension # RAS58RR – Provides additional support while maintaining a comfortable ride, but requires traditional steel leaf springs. It won't work with the optional composite mono leaf spring so I'd check if you have that.

-TorkLift StableLoad # TLA7310S – Provides extra support when needed and can be disengaged when unloaded. Requires factory lower overload springs, and diesel exhaust clearance could be an issue if your diesel truck has the short bed.

Could you tell me your bed length and whether your truck has traditional steel leaf springs or a composite mono-leaf setup? And if it has a factory overload spring.

I have the Firestone bag setup on my 2024 Chevrolet 1500 High Country. It is my trailer puller. I also added a compressor to mine with everything hidden and the gauge/control hidden inside the center council. Today I was towing my 20 ft. enclosed car trailer empty, and the wind was making the truck feel a little unstable. I bumped the air pressure to 30lbs. and the truck became more stable and smoother. I just added a 2026 Silverado to my truck collection, and I am adding bags to its rear suspension. I am also adding a hidden compressor but this time with a wireless remote control. I used to pull a 38 ft Hillsboro enclosed aluminum 5th wheel all over the states with Chevrolet 2500 single axle pickups. I had Firestone bags under those trucks. I just moved the bags every time I traded. They just had the lines t'd together with a Schrader valve in the bumper and an air bubble in the trailer. I'm definitely a bag man.

@GaryM Thanks for the feedback Gary! Sounds like you do quite a bit of heavy towing. Do you still pull 5th wheels or mainly the car trailer? You'll have to let me know which wireless compressor kit you go with and how you like it. I recommend the dual path so you can adjust each side individually if you ever need to do that. Otherwise the single path compressors work fine if your truck / trailer isn't normally unevenly weighted on the back end.

I have an air ride suspension on my 2023 Silverado 1500. I only use it for towing, otherwise I don’t air it up. But I freakin love it! On that note, I had to get very creative to find a place to mount the air tank. I ended up manufacturing my own tank mount. Still hard to find a place to mount it.

@Jeremy Nice, thanks for the feedback Jeremy! Yeah those compressors and tanks can be a little tricky when mounting. Where did you end up putting the compressor?

Andrew, The compressor fit on the passenger side frame without much problem. It was the tank that needed a creative solution. I found a spot on the driver side that barely worked, but not with the mounts that were supplied.

@Jeremy Oh okay gotcha. Yeah those tanks are a bit cumbersome when it comes to mounting them. Glad you got it figure out though!
