Air Lift Super Duty Bags Installed

I’m going to keep them intact and even throw on a few extra. Maybe you can stop by on your way to NoDak and we can install some jounces on your truck. I’ll show you how to drive the Black Hills with some authority.
Look at my install photos, you have to remove them. There won't be much room with those saucers in place of the jounce plate even without them. Don't forget to get the brake lines secured properly. That little connector is kind of a POS.

I'll be flying the next few times. Then I might be rolling through in October with my hunting dog! You can catch me rolling through Gilette, Wyoming on my way to Miles City, Montana. Plenty of mountains on that run!

Yeah I was kidding about the jounce plates, it’s all pretty straight forward.

I know, I was just kidding you too.

Get 'er done! Should be a good setup!

So if those bags run 0 psi, can you set up a Wireless One to run at 0? It would be a PIA to have to kill the power to the wireless unit and drop the pressure manually. If your not running the remote, then it doesn't really matter.

The Wireless One can’t run 0 psi to my knowledge.

So I'm not going back and reading the several pages added lol. I tuned out after I was told I was full of shit and I needed to play with more titties :rolleyes:

But my ZR2 bags came in yesterday and I tossed them on today. They seem to fit great, But haven't really tested them yet. BUT I did record a video showing that the freaking pressure Does infact go up in the bags as the suspension is compressed. Crazy that's even a debate. The ZR2 bags are a different part number then the standard bags. Yes they are all black bags that mount to the frame. They all look more or less a like. But they do make different ones. Sort of like shocks. They can look a like but they ain't the same. Does it matter? I don't know. My guess is it does. I doubt airlift just didn't want to sell bags to HD ZR2 and AT4X owners all year for shits and giggles. I doubt they came out with different air spring vs using the ones they already have for no reason.

If you bought a ZR2 for the ride quality, Running cradles and keeping the bags at zero or open will ride better. Open bags are like they aren't even there. When you compress the suspension. Like hit a bump. The pressure in the air springs goes up and adds resistance. The more you compress them the higher the pressure. The higher the pressure the stiffer the bag gets. It seems almost silly to have to say that. It should be obvious. But anyway here is a freaking video of my bags at 5 psi and me lowering a trailer down on the truck. The pressure goes up to 14.5 in only about 1.5". Trailer is 1500lb of tongue weight. Now imagine a 8k truck hitting a big bump and compressing the suspension several inches. What exactly do you think happens to the air spring?, LOL

And BTW at full droop my bags are not touching the cradles. When the truck is sitting on the ground the bags are in the craddles

Without all the BS back and forth I created, I agreed with what you were saying and I appreciate the video. Still waiting on my bags and compressor to arrive.
 
You are full of shit with respect to the claims you've made in this thread. Primarily 'cause you've raised concerns about a set up you never installed or tested. Yet everyone else who's run it said it isn't a problem and they really like how it performs. That debate ended before it started, cause guys had already logged 10s of thousands of miles on their bagged rigs without concern. But you can't come to terms with those facts for some reason.

What you've installed now is different and it's just another way of doing the same thing like decades gone bye. You, nor Air Lift solved any problem that we've had, cause there simply hasnt been one. If there is, I'll be sure to inform everyone.

I'm happy you found a solution that meets your needs. Now that you've rebuilt your front end after buying the wrong truck and have a clearly "superior" set of airbags 18 months into it, you should be happy for years to come...... just the same as the rest of us a couple weeks after we bought ours and installed our bags and towed away.

Have fun!

Also, that video doesn't tell anyone anything, cause the first thing I do with the smallest trailer I tow is put 15-20 psi in the bags cause I want the level ride and stability it provides.

"Newsflash".........airbags work best with air in them!

You might want to go back and re read my posts. I NEVER said your setup didn't work or was bad. All I said was the pressure in the bags goes up when the suspension compresses. I also said I just prefer to run my bags at no pressure when unloaded. I never said you should. I simply said I prefer it, because trucks ride better to me that way. If you can't feel the difference in open bags or them hitting 30+ psi on big bumps, that's great. But the pressure does go up and the bags do add more resistance as you compress them. They do not stay at 5psi. They will limit the up travel because of that. Its just how it works. By all means though, run whatever setup you want. My issue was telling me the pressure doesn't change and I was talking about bunch of bullshit. Everything i said was fact.

5 psi will always be 5 psi, cause your springs and shocks will be way ahead of it.

You guys should have played with more titties when your were younger instead of playing with your jounces!

I just had 20 psi in my bladder when I got of this plane. I sure as hell wasn't worried about having a jounce in there too!

Dude, I got to tell you this is some real bullshit. Pressure does not increase with weight. You ever air up tires on an 18 wheeler? Guess what 100 psi is a 100 psi, it doesn't matter what you have in the truck. Now you might want to run higher pressure with more weight, but you sure as hell dont get more pressure with weight. The bag will compress and flatten out, hence why its set back from the springs.

The only thing that will increase psi is temp due to sunlight or friction from rolling down the road.

Simple Physics = you have a stretching vessel, there's still 5 psi in the bags. It pancakes, you dont feel shit unless your ordered the jounce for a rough ride enhancement.

I run 12- 15 psi in my tires in the sand and the tires pancake out. There's no magic where sunddenly the tires gain pressure cause the truck weighs 9000 lbs and I'm driving around in the sand. I have to stop and air them up when I'm ready to leave.

When there's no additional volume added in the expanding/flexible vessel, the pressure doesn't increase.

🤣

Your argument is stoopid, cause it's not what happens in this application. If you choose to believe all of us that are running it must be wrong, thats on you. Nothing you said mattered for this setup, its 100% bullshit and that's 100% fact!

Hop on your bicycle with 5 psi in the tires and tell me how it goes. I'll bet it doesn't feel like 30 psi with your tongue weight. Now quote some more internet theory bullshit and tell yourself you're right, you're perfecting it with each post.

Are you ok man? What are you even talking about? I never quoted any internet anything about me being right, lol those quotes are what you said to me. I NEVER said your setup was wrong. I NEVER said it wouldn't work. I simply said the pressure increases in the bags when you compress them. You said that was bullshit. I proved it in a video that it wasn't bullshit. Your bags will work fine, lol. I never said they wouldn't.

You get on your 5 psi bicycle yet? How'd it work out? Did you try 10, 20, 30......oh it worked when you hit 40? Sounds about right, cause they feel good about 45 psi.

Why did you even waste your time with any of this? The fact of the matter is it has 0 bearing on the performance of this setup. I stated that unequivocally and others have validated it as well. Is that not good enough for you? Yet here you are working on page 10 trying to convince people it matters.

You've offered 0 value for anyone wanting to know what they might be able to do to improve their towing capacity like we have with this particular setup.

Why not just quit posting? Why not start your own thread if you think it matters so much? Why not go out and test your new setup for what it was meant to do? Why post stooopid videos testing a completely different setup to try to prove a point that everyone must feel the same as you dropping 1350 pounds straight down on a static truck (guess what, it aint the same as running down the road)?

I always was a little suspect when you posted the setup you did on your 1500. I would not have used those large bags with internal jounces, they weren't the right ones (should have been much smaller bags for a low tow rating rig) for that frame to axle clearance and you even later admitted it was so, so performance. Then when you went and bought a snow plow rig, that's when I sort of checked out on you and your suspension opinions.

I'll continue to call bullshit when I see it. The tally continues.........are you ok might be the real question.

So this Air Lift ZR2 video popped up in my YouTube feed......I wonder why?

This just seems like the exact same fitment as the kit I've installed 18 months ago. In fact, I think they used my install pictures and specific observations about the ZR2 to cobble together this kit. The only difference appears to be the cradles and they use the jounce bags for an enhanced stiffer ride when unloaded.

@8ball_99, I'd like to see your setup, cause in this video there clearly is no space below the bottom of the bag and cradle as you just described in your setup. I am very concerned that if you put 5 psi in these bags you are going to feel like you have 65 psi because of tight fit between the frame and axle, not to mention the dildo inside the bags......also molecules and stuff and things. Please report back!

I have no idea what your talking about with a bicycle. I guess since a bike rides better with 40 psi so does air bags on a unloaded truck?

I actually just posted in response to RedhotZR2 and when I brought up I figured the ZR2 kit would have cradles to allow you to run the bags at zero or open. You seem to take offense to that. Then you proceeded to go off how it doesn't make a difference. PSI in the bags never changes. 0 or 20psi doesn't change the ride quality, ECT. You argued with both of us for several pages when we said the pressure does increase as you compress the bag. We tried to explain to you why. But you just called bull shit. So I put my bags on and proved it. You still call bullshit. You are adamant that there is no point in the ZR2 kit. No point in running the bags open, ect. I disagree and explained why. I don't care what you do, But for anyone browsing on this site I'd rather them have all the information.

It's kind of simple,
Does pressure increase in bags as you compress them?= Yes
Does the bags get firmer and add more resistance as their PSI increases?=Yes
With those two facts in mind It's not crazy to say running the bags at 0 or open could/should offer a smoother ride when unloaded. That's literally ALL I've said. I NEVER said yours won't work. Literally the only difference in a ZR2 and other trims is the springs and shocks. Of course the standard kit bolts right up. That's great you think it rides great. That's great you can't feel the difference between 5 and 20psi. That's all subjective. I believe you. It feels great to you. I never said it didn't, lol. You defend the regular kit like you engineered it and hand fabricated it. It's just a bolt on kit. Just like the ZR2 specific kit is a bolt on kit. The regular HD Ultimate kit comes with airbags part number 84297 The ZR2 kit comes with part number 58496. Does it matter? I have no idea, I didn't make either kit. I'm going to run the ZR2 kit because I prefer my bags empty when I'm not loaded. Please by all means run the regular kit at what ever PSI you want. Again no one has told you other wise this entire thread.

Thanks for confirming they all sit the same on the axle and will all behave the same running down the road. Your 0 psi will be no different than 5 psi. Took you a while, but at least you came around.

I definitely engineered it, engineering by definition is effective and efficient. I looked at their website to see what was available. Watched a video of a regular 2500HD install. Figured out the only difference was the jounce and jounce plate. Ordered and installed it. Started towing like it was meant to be. No hand wringing, no waiting around for 18 months pontificating. No weird scientific anecdotes and hypothesis that dont mean shit in the real world. Just get it done........simple!
