Airlift Suspension

[Bwoodkid]

Ok, so I have Airlift 59565 ride control installed on my 2015 1500.  I've been hearing a clunk when I go over bumps in the parking lot or pulling into the driveway at home.  I cant tell where its coming from but sounds like its the bags??  Anyone else have this issue?

Interesting I'm looking at a similar if not same type kit. As I'm lowered 5". I would rather run a 2500 bag inside the frame up too low.

Is that pic at normal ride height?

If so I’d imagine you’re over-extending the bag...?

I thought the same thing. IMO I think there is a max of a inch up travel and a lot of down in that setup.

Just checked it says always maintain ride height, never exceed 40psi even with load.

Stick a peice of rubber uner the bolt the holds the bottom of the bag in. See if that works

Good idea I also have seen that they sell a plastic bag spacer mot that he needs it higher but nice Isolation

What happens to the bag when at full droop?

It looks like it’s fully extended at your ride height...and that wouldn’t be good.

They rip open. That is why a limited or the new Firestone 2500 have fully crimped bags still bad but better then rip. And you know all dealerships will just put it on the rack and lift it.

Pretty sure that’s your problem.

Your suspension will go to full droop even when driving, doesn’t have to be in a lift.

Depending on many things, including the condition of your shocks, a large compression movement like a speedbump can cycle to full droop on rebound.

While under load,  it compresses and gets fatter.  If that's what you mean.  I haven't had any problems yet.  other than the noise.  Now I'm hearing that gm has issues with the leaf spring knocking over bumps.

But if you aren’t under load, it appears to be stretched to the limit.

If your bags will tear at full droop, as you state, then that’s a problem.

In the pic it looks like ride height and there is more in the bag to go up or hang. As you dont see the bottom bag mount.
