gosh dern minitruckers...

WHY are you minitruckers so afraid of the sleeve style bags? The double convoluted bags have a really high spring rate, which makes them great for an a-arm front end or on the bars of a 4-link. But to use the double convoluted bags directly on top of the rear end has finally been proven as less satisfactory. Still, some of you who are on a budget will opt for the "on top of the axle" method (with a double convoluted part of course.) But the 140-95 Tapered part is a FAR superior part for directly on top of the axle. As a matter of fact, Firestone and Ford, together, designed the 140-95 part to be used on top of the axle. Ford uses them on all of there factory air-bagged trucks.

So tell me, why are you minitruckers so afraid of the sleeve bags? I promise I won't attack any one with an honest answer, I am very curious. I install them on just about every old car we do and we never have had a bag fail.

BTW- because they suck isn't an honest answer.

my guess would be the options of the numerous amount of double convulted bags, psi ratings, and being acustomed to it for a while!!! not sure though.

i love the f9000 ride, they just don't get the lift of a well designed lever setup

well, im not too familiar with sleeve bags but i was thinking, there is alot of movement involed with an active suspension and a peice of rubber that unrolls itself when it is lifted seems to have more of a wear factor, possibly rubbing on itself while lifting or lowering, compared to a convoluted bag which collapses, only subjecting a few areas of the air bag to wear. Just a thought

if they wore out easier, then 18 wheelers wouldn't use them for millions of miles

They are taller, when fully compressed.

They roll over on themselves and fold at the bottom, after time sitting at 0 psi I would think it damages the folded part of the bag. That is where they always start to leak on Lincolns.

They do ride smoother on an axle with minimal wieght on it.

Some of them, the bag hangs below the lower mount at 0psi doesnt it?

I had the 9000's on my s-10 a while back. Ditched them due to the fact that the bottoms are made of plastic. The weight of my truck sittin on 2 - 4inch hoops scared me. On top of that just to support my choice, the bolt and metal threads it went into ripped out of the bottom of the plastic sending the bag off the mount and making my truck immobile 20 minutes from home. So yes, they simply suck, and no, it wasn't my set-up. The mounts stayed horizontal all through travel...

I think alot of people think that they dont have as much lift. and second. they see whats in the magazines and thats what they do. i put sleeve bags on a colorado in the rear. turned out nice

they ripped out because you didn't limit them with shocks, not because they suck

Max another thing about the bags your talking about that 90 percent of people dont know is they are able to modified for different aplications by ordering different bottom mounts. Firestone has them from a stiff to soft spring rate. the stiffer the better response when towing. the softer the better ride. They are better bags but not able to have the 30% angle that the doubles are aloud to have so the use of them is on over the axle not cantilever.
