Question:

I see they include line, do they include the hardware to mount in rear where they would fill them or an add on kit is needed? Meaning are there provisions to run these with line in to fill the helper? I dont see that anywhere in the pictures.

Thanks for your question, Beau.

Are you referring to the mounting brackets and hardware? If so, then yes, the Air Lift kit part # AL39DQ includes everything you need to install the airbags.

Once installed, you’ll have two air fittings, one for each side. If you’d prefer to have one air fitting so both bags inflate at the same time with the same PSI, you’ll also need union tee part # AL21838.

For a complete setup, I recommend compressor kit part # AL25854. It’s a straightforward system that includes everything you’ll need for installation.

Keep in mind, you don’t have to use a compressor, as long as you’re fine stopping at a gas station for air, or if you have a way to inflate the bags at home before hitting the road.

If I missed what you were asking, just let me know and I can adjust!

Hey Beau, how did the Air Lift LoadLifter 5000 kit work out once you got it mounted? Did the fittings and hardware cover everything you needed for the rear setup? Your update could make it easier for others setting up the same system.
