This is what I am using.

Great price and great bags... You need to find a place they will fit and the range of motion is right...These have built in bump stops... When mounted they need to hold the buggy up off the ground when fully deflated.. My buggy was dragging before I put spacers under the bags,,, You don't want them to be fully extended before your limiting straps are tight... These double convuleted bags have a lot of forgiveness in alignment but get them fairly straight when the buggy is in its normal riding position and fully compressed. Bags are an excellant spring but may seem soft or stiff ,,depending on the shocks... Being able to adjust the bags is a real bonus..especially when crossing deep water or sitting sideways on a steep hill.

A good compressor for the money

I will be doing the airbag upgrade shortly also. I thought i read somewhere on here about putting antifreeze in the bags.Did i misread something or is there some logic to doing that.

Anti-freeze is used to reduce the volume of the bag. When you change the volume of the bag you change the spring rate. The only anti-freeze you need to worry about is in your radiator.

firebug, i believe i am running the re-6 bags, i love them. much smaller than firestones of same capacity, ride soooo nice, 4th gear down the railroad tracks nice... PLUS the slam specialties DO NOT expand out when compression occurs, meaning no clearance issues.

do you still use tortion bars with the bags?

Post subject:  Re: AirBag Suspension ?'s
It seems to me you would have to much of a spring rate to run both. I don't run springs with my bags.

got any pics of how your t-arms are connected to the tortion?

This is set up like the inboard trailing arm pivot. 3/4" chromolly heim only. Anything else or less will break.

What kind of air pressure are you guys running in your bags. I just put a set on my project and I don't know what they are rated for.

What size are they, length and diameter

That depends on where you mount them and the weight they can handle. Since you don’t know what they can handle you might want to measure them and find some on the internet close to the same size and diameter to get an idea what weight they will support. On my old rail I have 2500lb goodyears mounted about in the center of my 2x3’s, with one person I ran them at 60psi with two 70psi. I’m not sure what the burst rating is on them but most of the 2500lb bags I have seen on the net, close to the size I have, were good to at least 400psi. Dave Hix has the same bags I have and I think he said he ran them at 20psi. Typically you want a 20% suspension sag. On my old rail at 60psi my spring plates were about ½” away from the lower stops. I would just air them up and jump on the back of the buggy to see how it feels. Take a small compressor on a ride with you so you can fine tune them.

Hope this helps, Brad

Mike do you have an inside support (machined load boss) welded on the mounting plate for more strength?

The section the socket head threads into is just a little smaller than the inside of the torsion housing about an inch or so long, so yes it is.

Add it, it's not that difficult.

Whats that made out of a piece of tube with an end cap welded on with a hole drilled through it..
Author:  MadMike [ Sat Jan 24, 2009 5:49 pm ]
Post subject:  Re: AirBag Suspension ?'s
Ya, sotra. the end plate is drilled 1/16" smaller than the head of the 3/4" hex head bolt. Measure the hole with a mic and make the head about .001 smaller. Need a lathe to do it. That makes it a double shear, captive mount. The two shiney things are spacers that get pinched with the heim when the bolt tightens up.
