Air Bags

AirBags are a load carrying component of a suspension system. Consisting of a rubber bellows of various designs and a metal or plastic end cap they replace or are fitted in addition to the original vehicles metal springs. Most air suspension conversions are in reality just a swap from metal to rubber springs (although its actually a bit more complicated than that). Air bags should more accurately be described as air springs since they achieve the spring action on your vehicle. Technically they are variable rate and variable height air springs. More air equals a stiffer ride and less air equals a softer ride. There is a comfort window within which the bags work well in terms of both handling and ride quality. This comfort window is larger on our Quantum bags than on competitors as these bags were specifically designed for cars and small vans. We do a range of about 10 bags that serve most applications. About 4 bags serve 95% of our product range. We are also able to obtain other bags. Most Firestone and Dunlop bags can be swapped for our own which far exceed the specs for Firestone or Dunlop. Air springs are often just called bags, or bellows, or diaphragms or airbags or air bags. These terms all relate to the same thing.

AirRide offer air suspension kits for almost all vehicles, and parts for all air suspension conversions. These vary from basic bag and bracket/strut kits right up to very sophisticated computer controlled kits. These are all for sale in the shop. If your needs are not listed please call or email for more information, as we can probably still assist. These pages are being updated, so please do check back soon.

Union Custom Bag

Overview

We pride ourselves on supplying the very best kits available with components chosen for reliability and safety based upon 20 years designing, installing and supplying air suspension systems. No other company has our combination of experience, variety of air suspension markets dealt with, or product range. We never compromise on safety to get the headline costs down, and even our basic kits far exceed minimal functional requirements.

AirRide custom provides the best ride and versatility within the install process. AirRide gold is performance oriented and direct bolt on, as are AirLift kits.

Replacement Bags

Do you need a replacement bag but cannot see the numbers needed to find the correct one?

This is very common and with between 10,000 and 20,000 different airbags listed in the most common catalogues (with no universal search facility) you may well be having problems finding a replacement. This is something about which customers call daily. Cars and vans usually have a range of travel of between 4 and 7 inches. Most within a range of 5-6 inches. We therefore carry a stock of bags for the kits we make with ranges between 4 and 9 inches, and with diameters between 3 inches and 9 inches. From the bags we carry, and the ones we have made for us we can usually accommodate most customers replacement needs, however this can require a re-drill on the mounting holes sometimes.

Safety

For safety bags should always be replaced in pairs. If you have a motorhome then new kits are often a abetter alternative than replacing bags because new complete kits are often not much more than a set of bags, line sna fittings, and because many new kits come with a 5 year warranty (Dunlop Systems and components kits).

All car kits are fully circuit independant - 4 circuit, FBSS. We do not offer 2 circuit systems (airbags on same axle joined) for cars as they are neither safe nor legal for road use. For motorhomes each wheel should likewise be on a separate pneumatic circuit.

These bags are ideal for the rear of most vehicles including cars, vans, motor-homes, minibuses, trailers, and the like. They can also be used on the front of many vehicles that do not use Struts with integral airbags. These bags are also an ideal upgrade for failed bags and the multi-fitment end caps make the job easier in most cases. Vastly superior to most bags available on the market. If in doubt please call.

6 inch single convoluted bag.

6 inch diameter, 6.5 inch range, 2.5 inches compressed, works to 110psi and lifts up to 1000Kg ideally in use and 1350Kg (per bag). Lovely slim bag that does not expand when it is deflated like the double convoluted ones do. Ideal for confined spaces. Fabulous ride and handling on most vehicles. This is our bag of choice on cars - despite looking smaller than conventional double convoluted bags it has almost as much lift.

6 inch double convoluted.

6 inch diameter, 7.3 inch range, 3.3 inches compressed, working pressure 110psi, 1300Kg lift capacity. This bag needs an inch all round clearance and must not roll onto metalwork or premature failure will result. Ideal for cars Lifts the same load as the 7 inch version but needs more pressure which results in a very slightly sportier ride on heavy vehicles (motor-homes and vans that weight 3-4 times what a car does).

Bag and Valve Kit.

Able to fabricate your own brackets? You just want the bags, lines and valves? Then this kit is for you. It includes two 6 inch Quantum bags ideal for loads up to 2 tons (pair), plus quarter inch lines, airbag fittings and a pair of Schrader valves for inflation. This kit is available with the 6 inch bags or with 7 inch ones at the same cost, or with 6 inch single convoluted bags. Please add a note at checkout regarding choice of bag.

 

7 inch single convoluted bag.

7 inch diameter, 5 inch range, 2.5 inches compressed, works to 110psi and lifts up to 1150Kg ideally in use and 1750Kg max (per bag). Lovely slim bag that does not expand when it is deflated like the double convoluted ones do. Ideal for confined spaces. Fabulous ride and handling on most vehicles. Note this bag has one of the lowest ranges of operation so accurate bracket design with no lost motion essential.

7 inch double convoluted.

7 inch diameter, 9 inch range, 3.3 inches compressed, working pressure 110psi, 1300Kg lift capacity. This bag needs an inch all round clearance and must not roll onto metalwork or premature failure will result. Very durable heavy lifting bag. This is an ideal bag for much heavier loads such as motorhomes and even trailers BUT it does not tolerate off-axis operation - the top and bottom must be kept parallel in operation.

Bead Seal Bag - Double Convoluted

This bag is old technology. Ideal to replace broken or worn bags or for some inventive clients to build their own struts. This bag is single skinned without end-caps. It seals by being bolted down using 6 screws to a metal plate. It needs a minimum thickness of 6-8mm although 10-12mm is better if you are welding the plate to avoid distortion causing leaks. It goes without saying that you must not weld with the bag in place!! Lift just under 4 inches. Diameter 6 inches but expands as compresses. Replacement on existing installs.

 

Double Skinned Strut Bags

These Quantum Sport Double Convoluted bags are incredibly easy to fit to most struts under 54mm in diameter at the pressure tube. For larger struts please call. This is the heavy duty version of the single convoluted Quantum sport bag. Fabulous ride quality, incredible handling and easy to fit! So good you would not know it was on air. Great on cars up to about 1500Kg. Beyond this the ride quality reduces.

Large Bead Seal Bag

This airbag is large and well suited to front strut assemblies on large vehicles. This has a 3 inch clear center. The diameter is approx 7.5 inches at rest, and the height at rest is 7 inches. Compressed it is about 2 inches and inflated around 10 inches. Limited stocks only.

Firestone rolling sleeve small

3 inch diameter relaxed but 5 inches needed when inflated. Ideal for minor support applications where space is limited. Tolerant of off axis applications although as with all applications should be parallel at ride height. Linear spring rate as with all reversible sleeve bags so less critical to get the ride height in the sweet spot.

 

Firestone Tapered Sleeve Bag

Softer Bag ideal for lower wight applications. Tolerant of modest off axis operation. Top cap is 120mm diameter, lower fixing  cap is 90mm and fully extended height 300mm although ideal operation is around 200mm-250mm height. Lower bracket must have top hat design to avoid chaffing.

Dunlop 7 Inch Triple convoluted Airbag

This is a triple convoluted 7 inch airbag complete with end plates. It has a 1/8 female threaded hole for a fitting in the top. We can supply fittings for this at extra cost.

Firestone rolling sleeve small

3 inch diameter relaxed but 5 inches needed when inflated. Ideal for minor support applications where space is limited. Tolerant of off axis applications although as with all applications should be parallel at ride height. Linear spring rate as with all reversible sleeve bags so less critical to get the ride height in the sweet spot.
