air bags like a bug truck

[purg113]

the only thing i can come up with is like the air leaf suspention on some peterbuilt trucks.
could I maby mod my old spings to do this or am I just missing somthing simple?

that seems to be only for newer trucks mine is a 93 that and they just look like they would cost more than my whole truck

Diesel4me2 had a 4 corner bags system on his truck for awhile. It was quite the system but after an incident hauling his fiver, he went back to rear springs.
He's going to be at Darrins fall meet next weekend.

I recall his mess driving home from the 2009 ralley. Something about maybe useing a walmark parking lot to place some 4x4 lumber in the blown out bag on the rear or something around this... Sometimes we don't see whats happening till its about 1 mile too late. Didn't the bag move and rub the tire. Then blow out...

I've never had a bag blow out before nor have I ever heard of it. Normally they dry rot after 15+ years or develop a very slow leak.

We had a bag blow out on our walking floor trailer once. Other than that yeah its always the old develop a slow leak deal.

well my thinking is that they are almost standard equipment on OTR trucks so why would a unit close to them in style not work on our trucks?

A better picture.

These kits are quite pricey but hey, a new truck is 58,000 so a few grand for a better ride isn't all bad. I would think that the superduty kit could be adapted to our trucks relatively easily.

This is the system i was going to copy:

It's a 4 link design and is very heavily designed...

They talked me out of the z bar (the pic in the OP) because when you accelerate it really wantes to rise up. The 4 link doesnt.

I did an add on support air bag setup on the rear of mine that was a bit different than any of the kits to where the bag is mounted aft of the axle . I have a constant duty compressor on the system with an auto leveler that keeps it at a slight pressure at all times so it is always on air that keeps the ride softer when empty and keeps it level no matter what I load it down with. One day when I get to feeling rich and energetic, I'm going to add a second set of bags forward of the axle so it rocks on the 4 bag setup and will basically hardly ever find the springs, they will just be there for directional control.( they are doing a lot of that now)

I thought it was going to be something like $10K or higher. If that $3400 price is for everything to convert the rear suspension setup to their system...for what you're getting, that doesn't seem like a bad price to me. Not sure it's worth it to me, but that price doesn't seem out of line...

That does not include the auto leveling system but heck, you could plumb schrader valves in for under 25 bucks and save for the compressor at a later date.

Yeah, I caught that after my post...the compressor/leveling valve setup isn't mandatory, but it seems to me that, if you want air bags, you're going to want the leveling valve also. At the same time, I don't know what air compressors at that volume and leveling valves go for...for that matter, I imagine you could find a leveling valve at a big-rig wrecking yard that could be used in this setup.
