    Just looking for some advise in regards to placing the above to beef up my rear suspension for heavier loads. I have a f250SD and it sags a little with my trailer on it (not very worried about that) in the winter time with my spreader and a load of salt i have a bigger sag.

    what is the advantage of using the air bags vs timbren. Cost wise its cheaper to go with the tims.

    Well, Withthe air bags, you could let air out when your not carring a load, to ease the ride up, and then air them up with a ride. With Timbrens, its one ride and nothing else.

    I hope that made sense.

    No problems with my timbrens. Cheap, easy to install, and does the job like a charm.

    Air bags are a somewhat complicated system. You have to put a compressor and tank on the truck, no big deal, but then you have to plumb it all and as long as the hoses don't get a hole in them, you're fine. But if you come out one day and you're truck is sitting funny, you'll know why. Dollar for dollar, Timbrens are the way to go. They're super cheap, less than $300 in all applications, and they're basically bombproof. Air bags, on the other hand, are just another entity on the truck that could malfunction and unless you have a specified application that requires the use of airbags, it's a waste of money because good systems with dual guages and all the goodies is at least $450+. With Timbrens you don't have the adjustability, but say you don't want them on there in the summer just take them off, they're way easy to install.

    I agree with what Scag48 said. With the Timbrens the truck's suspension has to settle about 1.5 inches before the timbren touches the overload perch. The ride is maybe 5% more stiff than stock. Timbrens can easily be removed in 10 minutes tops.

    i have air bags in my expedition.. ive moved around a bobcat a few times and its pretty crazy how the truck doesn't sag once the bags fill up. i dont think its practical putting on an aftermarket system though...

    I just had timbrens put on the rear of my F350 last week. Didn't seem to change the ride any until I hooked up the hydroseeder behind it. I had about a 14K load on a pintle hitch and it didn't sag much, if any.

    I have airbags in my truck and love them, if you search under my name you can find pictures of them. I just took them down from 50 PSI to 15 for when I go away tomorow so the ride isnt as rough.

    Installed the Firestone incoil airbags 2 years ago. Made a big difference, but one started to leak after a few month, the other one started to leak within one year. I'll switch to the Timbrens.
