Airbags?

[pnwobrigade]

Where did you order from?

Michigan Truck Spring, in stock and quick shipping

Don’t have the Eibachs yet, but my wife wants to go camping this weekend and I had a couple hours to burn after work today. Figured I could at least try out the bags and see how she tows our Ember TT.

I’m guessing the installation instructions from AirLift have you completely remove the springs for safety. I can’t see any other reason because it is SUPER easy leaving the springs in and just jacking up either side. I went with the 2 into 1 setup with one valve for a cleaner install and since I don’t see any reason why I would need to have the springs not at equal pressure.

It could be my measuring was a little inconsistent, but it seems like with just the bags in at atmospheric pressure, the rear end is about 1/4” higher than before.

Even more surprising (in a good way) is that with only 15 psi, it’s raised up about 5/8” unloaded.

Headed out now to do a quick drive to see how they are unloaded and then hook up the camper.

@MORK did you install the upper spacers as well?

Anxiously awaiting your next post!!

Interesting - what psi were you running? I imagine that with how far these coils expand, you could only run so many psi before a bubble like that would protrude.

Finished install for reference:
View attachment 402320
View attachment 402321
I’m also quite happy with my Schrader location

With no load, I’ve been keeping at most a couple psi in them so they maintain contact pressure - even at 5psi, you can notice the increased spring rate.

Running about 40 PSI. Swapping out for HD 1000 Raptor. Since I will be changing the airbags, I am changing the spring with 1.5 inch lift Eibachs. I'm still struggling on if I can remove the tailgate without messing up the 360 cameras. I have had some conflicting info.

Does one lose any travel with bags?

@MrHomeGuy kudos on valve positioning wish I saw this prior to installing mine

If its Gen 3 , the air lift coil bag sits inside the coil so the travel should be standard OEM, bags should have minimum pressure so spring can move.

If Gen 2 , leaf spring, best to use a DayStar cradle for bottom of air bag which will not restrict the travel since the bottom of airbag is NOT attached to the axle.

Where did you place yours? I skipped the compressor kit for now as I don't think I will be changing the pressure much while set.

Gen 3 (we're in gen 3 forums)

So no loss of travel? Those spacers they include don't limit anything?

Finally got around to installing the airbags this weekend.
The install can be done without removing the springs but it sure was a pain to squeeze the airbag in between the spring, the more you flatten it the wider it makes it.
Overall straight forward install, I ran the airlines through the frame from the top of the spring to the back near the bumper as you can see photos. I used 3/8" wire loom around the airlines in the locations that it makes contact with an edge to protect it.
I haven't mounted the valve yet and wanted to see how everyone else was doing it. I like the idea through the license plate screws.
@Ox3721 did you drill through the hitch mount for the valve or is that an existing hole?

I took some measurements and at 5psi I see about 1/4" or so of lift in the rear from stock. At 30psi with no load it raised the rear 1".
