Triple Bellow Air Spring 2600 lb Air Suspension Bags 1/2"NPT | Single Port Universal Replacement Helper Springs for Trucks, 2 Pack

Bags work great good quality

Love them

I have a personnel lift that I want to be able to operate without having to remove it from my utility trailer. In order for it to operate correctly, the base- i.e. the trailer floor, needs to be level. By installing these maXpeedingrods Pack of 2 Triple Bellow Air Springs on my trailer axle and using independent air controls and a small 12 volt compressor, I will be able to level the trailer using the tongue jack stand as the third support point. These air springs will also add to the stiffness of the trailer leaf springs to establish a stable platform. These are an economical solution for my project requirement. They seem well-built and the roughly 6 inch travel makes them applicable to a variety of uses.

The quality of these airbags is excellent; they ride really well. They were easy to install. All you had to do was read the instructions for sure. So clear and simple and made it really simple to follow I really think that's excellent value for the money. I'm really glad I got it

If your air suspention bags have failed and leak these are a good replacement solution. These seem to be well crafted and will get your suspention back to it's former glory. These are good parts from a known parts supplier. Recommended.

I have been through three sets of these for my kids’ vehicles. Very frustrated about the rings busting. Both happened while driving which could have been very dangerous

They seemed fine and the size was what I wanted. I don't care for them as they leaked and seem pretty flimsy and doubt they will be off any use for offroading applications.

Got these for an ongoing project building up a leveling system for my van. These seem to be airbags with the most amount of travel for that task. They're also not super heavy like some. A lot of work ahead to see how well these hold up, but I'm hopeful from what I see so far.

These maXpeedingrods air springs are durable and effective. I got these because I wanted a simple replacement option for an air suspension setup without spending a fortune. The pair arrived well packaged and the air springs look substantial. The rubber feels thick and the design looks like it can handle movement and load without feeling flimsy. The hardware area and the single port fitting are straightforward and the 1/2 inch NPT port is a common size, which is helpful if you already have lines and fittings you plan to reuse. The bags look like proper universal style replacements rather than something oddly shaped that forces you into a custom workaround. Installation is fine if you have basic tools and you are comfortable working under a vehicle. The main thing is making sure the mounting points line up with your setup and that the bags sit straight so they inflate evenly. Once mounted, the air connection is simple with the single port. You attach the fitting, run the line, and check for leaks. I always recommend using thread sealant or tape where appropriate and then doing a careful soapy water leak check after the first inflate because even a tiny leak will slowly ruin the whole system. In use, these do exactly what you want an air spring to do. They support the load and help keep the rear end from squatting. The triple bellow design gives a nice range of motion and feels stable, especially when the vehicle is loaded. It makes the ride feel more controlled and it reduces that floating feeling you can get when the suspension is overwhelmed. Even if you are not towing all the time, it is nice to have the ability to add air when needed and then drop it down when you are driving empty. The only drawback with universal replacement air bags is that you need to confirm your measurements and your mounting style. Universal does not always mean perfect fit for every setup without some adjustment. Also, like any air suspension component, longevity comes down to proper installation, good alignment, and keeping the air lines and fittings sealed. If the fittings are not done carefully, you can end up blaming the bag for what is really a leak at the connection. Overall, this is a solid value replacement set. The bags feel well made, the 1/2 inch NPT single port setup is simple, and the load support is exactly what you want for leveling and stability. If you need dependable air springs without paying premium prices, this set gets the job done. Full marks from me!

I have been running these universal triple bellow bags for about four months now on my silverado 1500. I decided to pick them up because my stock suspension was starting to feel tired; specifically when hauling my work trailer or a bed full of lumber. I needed something that could handle the weight without making the truck ride like a brick when it was empty... and these seemed like a solid experiment for the price. The installation was surprisingly straightforward. Since these are universal 2600 lbs bags, they don't come with vehicle-specific mounting brackets, which I knew going in. I had to reuse some plates from my old setup, but once I got the alignment right, it was easy to install. The 1/2 inch npt port is massive compared to the standard 1/4 inch ones you usually see; this is great for airflow if you want the bags to inflate quickly, though I had to use a reducer bushing to fit my existing lines.​ What I really love is the technical design of the triple bellow. Unlike the standard double bellows I've used before, the extra fold in the rubber gives you significantly more travel stroke. This means I can drop the pressure low for a soft highway cruise or pump them up to 100 psi to level out a heavy load without bottoming out. The good cushioning is noticeable immediately; it absorbs the road bumps way better than the factory bump stops ever did. ​ There is one minor annoyance with going the universal route: you really have to be careful with your clearance. Because these are slightly taller and wider than some stock helper bags, I had to double-check that they weren't rubbing against frame rail or anything else. Also, make sure you use plenty of thread tape on that single port connection; the large diameter means more surface area for potential air leaks if you aren't generous with the sealant. ​ Overall, I love it. They hold pressure well and gave me back the ride quality I was missing. If you are comfortable doing a little custom fitting, it is a fantastic upgrade.

These air springs feel solid and well built right out of the box. The triple bellow design looks durable and gives confidence that they can handle heavier loads without issue. Installation was straightforward as a universal replacement, and the 1/2 inch NPT single port fit my setup without any problems. Once installed, they inflated evenly and provided good support for load leveling. Performance has been consistent so far with no noticeable leaks or drop in pressure. They handle weight well and help improve ride stability when hauling or towing. Overall it is a dependable air spring set that does what it is supposed to do, offering solid support and stability for suspension setups.

These airbags are EXACTLY what i have been lookinh for. Ive got a 6x12 3500lb axle utility trailer i use for landscaping trailer. I constantly find myself overloading it weight size. After a call with my grandpa, he suggested I put helper springs in it. I was going to go with the traditional steel coil spring style helper spring, until I saw these. I really like the idea of being able to adjust the air, so my trailer doesnt have to ride super rough when I overload it depending on how overloaded I am. The installation was a bit difficult, but thats because I had to custom fabricate mounts to make my trailer accept and hold these properly. If you were to use these in a normal application, it would probably be way easier. After several months of hard use, theyre still rocking quite well! The bags are made of a heavy duty rubber and quality steel. No doubt guaranteed to last long term.

This set is an awesome value. It’s triple bellow airbags that provides large improvement in load support, towing stability, and ride control. When carrying weight, the vehicle stays level and feels more planted, while unloaded driving remains comfortable and smooth. The materials is thick and feels well made, with solid construction that gives me confidence for long term use. Based on prior experience with Maxspeedingrod products, the quality here is consistent and known for great value. A mechanic inspection confirmed good travel range and material rigidity, which should handle various sized loads without sacrificing comfort. Paired with a compatible compressor system, these airbags are a practical upgrade for anyone looking to improve ride quality, stability, and control when hauling or towing. If you’re looking for bags for the price and quality you really can’t go wrong.
