SRW and Airbags

Reading over the forums in the last few weeks I get the impression most of you without dual rear wheels use one of the two airbag modifications as the Montanas and Mountaineers have significant pin weights. If you have a 1 or 3/4 ton SRW TV and have airbags, have you always been satisified with them or could I do without? Has anyone had any new truck warranty complications? Thanks for your advice.

I only added airbags because my TV squatted a bit when hooked up. Levels the truck and smooths the ride a bit. I let the air out to 5-10# when not towing or hauling.

Never had a problem with the 04 2500HD GMC squatting with the Mountaineer hitched. IIRC, our pin weight may be a couple hundred less than yours. I think the 3500 should handle that extra weight though. We'll see what the new Chevy does. Doesn't have a hitch in it yet.

The ONLY thing air bags will do is level the TV. They do not add to the ability to carry the PW or to the cargo capacity of the truck.

I don't have airbags on my F350. And my 3075RL has the heaviest pin weight of any of the Montanas, even the longest ones.
As far as F250s, some have helper (or overload) springs and some do not. The helper springs come with the F250 camper package option. And maybe some other options?

I had trouble with the 09 Dodge squatting. Instead of airbags I added timbrens. Have been very happy with them. Corrected the squat, improved the handling, zero maintenance, and a lot less money. Having never had airbags I cannot speak to the "difference of ride" except to say I am happy with what I got.

I installed factory overload springs on my Ford F-250 to match an F-250 which increased my GVWR and will be added large wheels and tires to support the new weight and complete the transition, however they don't prevent sag. When trucks are loaded they will sag, some more that others. If you are sagging TOO much you might be overloaded and most after-market products will not increase the GVWR (look at the fine print) especially air bags.

The air bags do 3 things: 1) eliminate the sag by raising the rear end; 2) help put the headlight aim at the right angle instead of making your headlights look like highbeams to opposing traffic; 3.) improve the ride when under a heavy load making the ride smoother - eliminating some clunking and stuttering.

Your rig combination may not need it. But you will be the best one in determining that especially if you are seeing any of the 3 problems I mention. In my case, my Monty sagged my rear end quite a bit so the air bags helped me a lot. I got a huge return on all three benefits listed above. Even DW noticed the difference in the ride. I use 15# when empty and about 60# when hitched up. When carrying cargo I measure the distance between the wheel fender well and the top of the tire. Then after loading up the truck I put in enough air to achieve the same distance, then the aspect is the same as when the truck is almost empty.

I have not had any complications from the dealer/warranty in regards to the addition of the air bags (most service guys tell me, "very nice addition" when they see them). I had them installed 7 months after owning the truck back in 2006 and I still have an active warranty.

I installed Firestone Air bags after 7 years made the first 1,700 mile trip last week with them I no longer have the squat and has improved the ride. So bottom line I am glad I did.

My combo GMC 2500 GMC and 2955RL

I have a GM 3500 SRW. The springs are identical to the dually. Like Chris mentioned in the first reply, the air bags help restore the truck to level. All GM trucks have progressive springs. That means they DO sag when you put weight on them. If your truck doesn't drop an inch or more when you set 2000# of trailer pin weight on it, then your springs are broken and bottomed out. Air bags can help get rid of this sag but may not eliminate it entirely.

I use the airbags and like the "ride" they provide.

I have the Firestone Air Bags for the sole purpose of leveling the rig when towing, nothing else. They work work well for that.

Put airbags in after a year w/o. Ride smoothed out a lot. Less movement in the rear of the 5er and the truck rides much nicer. Only use 35lbs in the bags.

If I were you I wouldn't add air bags unless my truck was squatting.
