Heavy loads can cause the back of your vehicle to sag and add unnecessary stress to your suspension. This stress not only affects your brakes in a bad way, but your tires, headlight aim and handling suffer as well. To improve your vehicle's ability to endure heavy loads, you need to add support to your existing coil springs.

Air Lift's AirLift 1000HD adjustable air springs have 2,100 pounds of load-leveling capacity and are made specifically to fit inside your rear coil spring suspension for additional load assistance. You can inflate and deflate these tough, molded polyurethane helper springs as needed, ensuring the perfect amount of support for every load, every time. Easily level your vehicle front to rear, and if you run dual air lines to the air springs at installation, then you can inflate the springs independently of one another for side-to-side leveling. AirLift 1000HD is a breeze to install with standard tools and comes with an easy-to-follow instruction manual.

AirLift 1000HD comes with manual inflation valves that are typically mounted on the bumper but can be installed anywhere on your vehicle for easy access. For even more convenience and control, you can add a compressor and gauge system (sold separately), which will let you monitor and automatically inflate your air springs.

Air Lift kits are designed to keep your vehicle at normal ride height. You can find the normal ride height of your vehicle by unloading it and measuring the distance between the bottom edge of your wheel well and the center of the hub. After you find and record this distance, you can regulate the amount of air that you put into your air springs to maintain normal ride height - even when you are hauling a heavy load. You will need to adjust the air pressure in your air bags according to the size of your load.

Air Lift is positive that you will benefit from their air spring suspension system - so much so that they offer a 60-day satisfaction guarantee. Install and use AirLift 1000HD springs for 60 days, and if you are not satisfied at the end of this time, you can remove them from your vehicle and return them for a full product refund.

2014 Dodge Ram Pickup

This product has leveled my 2014 Ram 1500 under any load from my camper to my pipe top trailer with farm equipment and even put 1500 pounds over the axel and it just sat level. I just keep a consistent 40 pounds in there and they work great!!

Perfect still 40 pounds and drug a camper all over the US with no issues.
Christopher - 04/24/2022


The bags seems great so far, Ive only done trailer set up with a short tow so far but almost no rear end sag with my 18' toyhauler. My reduction to 4 stars is the install instructions. You need to soak the bags in hot water to make a correct hotdog bun shape. Also, for me, finger tight on the bag air line connection wasn't sufficient, the connections kept backing off from vibration during driving. I needed teflon tape and little extra "snug" with some channelocks.

2017 Dodge Ram Pickup

A little bit of buyers remorse, Not overly impressed, in hindsight I should have got one of the better airbag systems. This particular set up with the bag inside the spring doesn’t “lift” the rear end to correct squat after a trailers Tongue weight is added, but it will stiffin the springs to only reduce squat - it must be set prior to imposing a load- on my 2017 Ram 1500. My trailer tongue weight it’s about 700 pounds

Install tip: The zip tie trick some guys are using online videos is legit and works

My original review is still valid. They do seam to be holding up - keep in mind, we only need to use them about once a month. Also, I was able to install the pump and intake filter in well protected spots so they don’t get much undercarriage abuse.
Galen - 03/13/2021


Product was well made, great instructions, but not very easy to install. I’ve worked on trucks my entire life (over 45 yrs) and this took way longer than it should have. Getting the bellows inside the coils was tough. Then the tubing was very difficult to get onto fittings. I give it 4 stars because of the quality parts, installation aspect gets 1 Star.

Product is working as promised and have not had any issues. Hauled many items over the year without one single problem.
Andrew - 04/30/2021


They did a good job of keeping my Ram 1500 level when towing, but they were VERY tough to install. Took my wife and I a lot of effort to squeeze the thick rubber into the coil. Doesn't affect performance or my rating, just know that if you buy these.


80 year old installed in 6 hours including leak check, follow instructions take inner fender wells a must.


I have truck with slide in camper. These are necessary and work great


Very good product. I installed then on my 2019 Ram 1500 for assistance when pulling a 7k pound trailer. The handling was improved - Our first trip was about 5k miles roundtrip. I highly recommend.

My review remains excellent. Any concern that the product will not function over time are gone. It has been two years and they work the same as day one!
Raymond S - 03/25/2021


Easy to install works very well just need a little extra support when towing heavy loads. 12/2019 1200 mile trip 2019 ram. 1500 1000 pounds in the bed and towed 7000 pound trailer no problems.


Your products are always top notch. The one time I needed customer service the company, Malone, were amazingly helpful. Always shop etrailer for my suff. Thank You


After a year and still working great!


Arrived in good shape fast shipping, soon the weather is good I will install, but was very happy with the same ones I put on my other Ram

2015 Dodge Ram Pickup

Great air lift system for my 2015 Ram 1500. Improved towing load leveling and ride. Had these on a previous vehicle years ago and they worked great then too. I would recommend to anyone wanting to improve ride and handling when heavily loaded.

As expected, no problems just a nice level ride. etrailer did a great job fulfilling my order and answered all my questions prior to purchase. Great experience.
Lloyd W - 10/16/2020


Air bags work well. Kept they trailer with load level. Also helped with sway. Instalation was a bit of a pain. Instructions would be better off tell installer to remove springs to put in. Other than that good product.


These things really help level my truck and trailer out. The installation was a little difficult but definitely doable. I would definitely by these again for another truck if required.

2019 Dodge Ram Pickup

Well worth the investment . Easy to install as long as you remove the fender well. Changed my confidence level towing my 26' travel trailer 2019 Ram 1500.


So far very pleased with removing the sag. Hardest part of installation was rolling the bags into hot dog buns and zip tying them then wrestling them through the gap in the coil spring. I used all PTC fittings and not the barbed hose fittings supplied. I ordered PTC T fitting from E-trailer and others separately from other sources although I think they are buried somewhere in the depths of the e-trailer website. Firestone sells them under their brand name. Other tips like spraying the bags and springs down with soapy water BEFORE sliding in through the springs helped a bunch. Remove the plastic wheel wells and spare tire to make installation easier. Also, covered all my air lines with wire loom to protect it from abrasion.

2012 Ram 1500

Arrived 3 days early. Just as great as the last air lift system I ordered!


Etrailer was exactly what I ordered and it was delivered by the said date...will definitely do business again. Thank you


They worked 100% as advanced

Still working great
Doug G - 01/10/2022


Got them on Tuesday, Installed them on Wednesday. I had trouble installing them per instructions. I removed the coiled springs to install them. More work but easier installation. Haven't pulled the boat or camper yet.


Product was not easy to put in. But with a little patience and knowledge it went smoothly.

Dodge Ram Pickup

If your truck will take the Firestone Airbag I recommend those but if you have a half ton Ram with coil springs these are the ticket. They made it so I could comfortably hook up a trailer with 720# tongue weight. I had 5 inches of drop in the back before and after adding the in spring air back I only had about one inch drop. Power was not a problem just handling. In my opinion these are your best option since the regular air bags will not work.


The only hard part was figuring what model would fit my truck and installing the bags. I did not remove the spring to install them. I squashed them between the coils. It was kind of hard to do but I did not have the tools to remove the springs to install them.


I found it easier to go ahead and pull the spring out and put the bag in from the top.To pull the spring out can be done by removing bottom shock bolts, no spring compressor needed. I tested the bags with a ton, they worked very well.

Ask the Experts about this Air Lift Vehicle Suspension

  • Differences Between Air Lift 1000 and 1000HD Coil Helper Springs for 2016 Ram 1500
    The difference between the two is how much weight they can support. The Air Lift 1000 # AL60818 can support 1000 lbs, while the # AL60818HD can support 2100 lbs. Going with the higher rated option, # AL60818HD is recommended. Because the system is very adjustable according to how much air pressure is added to the system, there's nothing wrong with going with a little overkill. I've linked to product description and install videos.

  • Are Dimensions Same Between Airlift 1000 and Airlift 1000HD
    Yes, the HD version of the Air Lift part # AL60818HD is the same dimensions as non-HD version # AL60818. While we haven't confirmed the fit of either in your vehicle from Air Lift I'm glad you were able to install it without issue. I don't foresee you needing the additional weight capacity of the HD since your Durango is a lighter duty vehicle but the HD will fit exactly like the non-HD model.

  • Recommended Air Lift Suspension Enhancement System for 2017 Ram 1500
    Between the two Air Lift systems you mentioned in your question I recommend going with the Air Lift AirLift 1000HD Air Helper Springs # AL60818HD as long as you don't have the factory Air Suspension system on your Ram. These air springs feature a load-leveling capacity of up to 2,100 pounds which should be plenty to help bring the rear of your Ram back up with the golf cart loaded, but unlike with the jounce-style springs of the discontinued AirCell , your ride quality when empty won't...

  • Suspension Enhancement Recommendation for 2014 Ram 1500 Thats Smoother Ride than Timbren
    TImbrens provide great suspension support but they have a reputation as providing a rough ride quality. They'll have to come off if you want to improve the ride quality as adding more support won't help. The best solution would be to replace them with the Air Lift kit part # AL60818HD that you mentioned as this allows you to adjust how much support you have so that you can balance support and ride quality. Going with too much air pressure will give you a harsh ride quality too.

    The AirLift 1000HD Air Helper Spring kit # AL60818HD which fits your 2012 Ram 1500 can often be used along with aftermarket progressive-rate coil springs but in order to tell you with 100% certainty we need to review two key spring dimensions with AirLift. What we need you to measure is 1) the inside diameter of those aftermarket springs and 2) the inside height within the coils with the unloaded vehicle at rest on level ground.

  • Should I Use the Air Lift 1000 Air Bags If I've Already Got a Weight Distribution Hitch
    Yes. A weight distribution hitch is always a great solution for helping re-distribute the tongue weight of your trailer over both axles of your 2016 Ram 1500, but there are instances where the tongue weight is still causing some sag. When this occurs, or you just want a second layer of support, adding an air bag like the Air Lift 1000 # AL60818HD to your rig is a great choice. These air bags work to help provide support to your coil spring suspension and just give you a little extra help...

  • Can Air Lift 1000HD Air Bags Be Used To Raise the Rear Ride Height To Level With the Higher Front?
    The Air Lift 1000 Heavy Duty Air Helper Springs # AL60818HD are only designed to work with your existing suspension system and provide additional stability for heavy loads on your 2012 Ram 1500. The springs are not designed to raise your factory suspension for the stance that you are looking for. If you were to add air pressure to the springs without any weight on the rear suspension it would likely raise the suspension but you would notice a harsher ride. With the age of your Ram you...

  • Air Lift HD 1000 AL60818HD Load Support Capacity
    The bags and lines of the Air Lift 1000 Heavy Duty Air Helper Springs for Coil Springs # AL60818HD that you referenced are capable of supporting up to 2,100 lbs. So while I don't know what video you are referring to it is very possible the bags just weren't aired up to the point that they'd get rid of all of the suspension sag.

  • Troubleshooting Vehicle Still Sagging With Air Lift 1000 Heavy Duty Air Helper Springs
    According to Air Lift, spacers cannot be added to the # AL60818HD. In order to minimize any sag make sure you are pre-loading the air bags. Air should be added when the vehicle is unloaded so that they can properly expand within your coil springs. If you inflate the air bags with the vehicle loaded they will not be effective.

    Since your trailer is a bit heavier I would go with the HD version of the Air Lift springs that fit your 2013 Ram 1500 with the part # AL60818HD since they are capable of supporting more weight. There really isn't a downside to going with the higher rated kit aside from a slight price difference. But the extra support will be nice to have.

As to the popularity of the # AL60818 over the # AL60818HD, it will actually have to do with the capacities as well.
