Air Bags on my truck

Installed a set of airbags on my Ram 1500, easy install, about 2 hours total. Routed the air lines to rear. You keep from 5-30 psi, depending on load. I have coil springs and these slip inside. With 15 psi the truck does not squat while hooked up and remains level. Air Lift 60818 Air Helper Springs Dodge Ram 1500 2009-2016

You need air-lifts to tow the 19? Or are you getting ready for the next trailer? you know the one your getting after the 19.

The Ram since 2009 has coil springs in the rear and rides real soft, but they do not support a load like conventional leaf springs. My older Ram had these bags and they worked perfectly.

The Ram pickups (1500 starting in 2009 model year, and 2500/3500 starting with 2014 model year) get this easy installation because they have coils. Leaf-spring trucks need a different type of air spring with upper and lower mounting brackets.

Any style of spring (coil, lead, torsion bar, air) can be as soft or as stiff as the designer wants. Although Ram designers chose relatively soft in this case, that was not required by the coil design; they probably found that they could go softer than the previous leaf setup (for better ride and handling under the light loads typical of these vehicles) because the control arms provide very good control - a leaf needs to be stiff to avoid windup and lateral flex, so you can't have both good control and soft springs. There are heavy-duty coil suspensions (even independent, such as Meritor ProTec) up to at least 14 tons capacity - they're not soft.

I believe that the intended solution for Ram pickup owners who want better load handling capacity is to get the optional air suspension (available in any year and model with rear coil springs). The Coil-Rite or Airlift 1000 bags are an inexpensive (albeit less functional) alternative to the full air system. Ram 1500 owners who didn't get the factory air suspension but now want a full air system (replacing the coils rather than adding bags to them), can buy an AirConversion kit from Firestone.

so you just jack up truck to take the load off the springs and insert the airbag flattened?
in that second pic..the air nipple is to the left of the hitch and you have a tee on the lines to the airbags so you just use one air nipple?

looks pretty simple and probably more reliable compared to the complexity of some air systems...guess it might be a bit weird towing or driving if only one fails.....so guessing that you think these are needed or just make it better when towing an Escape 19 with the Ram?
thanks for sharing

Have the firestones on truck . They were put there because of having a camper . They have been on truck for over 12 years . They have at least 5 lb air at all times .if I find truck is a little low put a little air . Pat

Yes, that's almost it with these bags for any vehicle. Some vehicles (not the Ram 1500) have hardware (mounting bolts, bump stops...) in the middle of the coil which needs to be removed; in some cases a spacer is needed at one or both ends of the bag.

These bags can be installed with a tee to one fill valve, or two separate valves. One valve is more convenient to adjust, but in a sustained turn the air moves from the outside to inside bag; with a separate system the air bags add resistance to leaning in a turn.

That's a tidy valve mounting job, Jim.
Another solution which is often used (although it is only practical on some vehicles) is to run the fill valves through the license plate mounting holes - they serve as the plate bolts.
I put the valves on a small custom bracket strapped (with stainless steel hose clamps) to the tube of the hitch receiver structure.

The difference is mostly an air pump, plumbing, and controls. You can use all of that with these bags, too, if you want automatic height control and easy adjustment from the driver's seat. With the full air suspension systems you need a pump and control valve to maintain spring force despite minor leaks; with any add-on system (bags in coils or separate air springs) you can get away with manually adding air, since a loss of air doesn't disable the vehicle.

If they are connected and one fails (or any of the line or fittings) all the pressure is lost from both bags, and you're back to stock suspension. If they are separate only one side is lost which is a little strange but probably better for the short term than losing both.

Might not be room these days, but when I put them on my Ranger some years ago I put the valves behind the gas filler door.

Same here as Jim, stock truck springs are soft. I went with the easy install sumosprings instead of the more complicated airbags on a tacoma. So far so good with loads in the back. I have yet to try it out towing a trailer. It will be fun to see how they work out. There is no gap to the frame where they touch so I'd hope the squat will be slight. With some brand airbags you have to be aware when you have your oil changed. When the truck goes on the lift, the axle hanging freely down could tear the bag if the bags bolt with both top and bottom. This according to other owners feedback, not me. But every brand is different. Thanks for sharing your photos. Did you need a coil spring compressor for this install? ESP truck accessories is coming out with a nice under seat storage unit for your 1500 https://www.instagram.com/esptruck/

"You need air-lifts to tow the 19?" It's not just the trailer for some of us. Some of us load up the back of our truck with a bunch of gear and pile of firewood.

PS-Sumospring example here if anyone is interested
