Air Bag Helper Springs For a 2018 GMC Yukon With Dobinsons 2" Rear Lift Springs

Question:

I have 2018 Yukon with Dobinsons 2” lift rear coil springs Part C09-045 will the F4108 bags still work or will I need a taller bag and what part number for it? Is there a Firestone bag comparable to the airlift bag part #60913?

I reached out to Dobinsons and they recommended using the Air Lift 1000 Universal Air Spring Kit # AL42XV(60913) with their springs. They did not have any compatibility information regarding the Firestone # F4108 but as those are for the OE springs they are going to be shorter than the Air Lift which is known to fit. I do not see Firestone having bags that will be as tall as the Air Lift.
