Before you can begin to clearly identify the pros and cons of an air bag suspension, you need to understand the design of an airbag system.
An air suspension system is powered by either an electric pump or compressor that forces air into airbags typically made from polyurethane and textile-reinforced rubber. The compressor inflates the bags to the desired air pressure.
It’s important to note that the air inside the airbag does the work of keeping the suspension level. (Air suspension should not be confused with a hydropneumatics suspension which uses pressurized hydraulic liquid instead of air.)
What is an Air Ride Suspension kit?
The kind of airbag suspension we’re discussing is designed to assist the leaf spring suspension installed at the factory. Air ride kits for the rear replace the factory bump stops, sitting over the axle between the frame and the leaf spring. It’s recommended that only a qualified dealer should install one of their airbag suspension kits. It’s definitely not a job for amateurs!
There are no shortcuts when it comes to installing an air ride suspension for a half-ton pickup truck. The basic components of an airbag suspension upgrade are listed below:
- 2 airbags
The average Airbag Man kit for a half ton pickup costs about $1000.00 US. Any additional features like air compressors, air tanks, and height-control valves for onboard air supply cost extra.
The Pros and Cons of Air Ride Suspension
The Pros: What are the main reasons for using an air bag suspension?
Comfort
Car and truck manufacturers are increasingly turning to air suspension as a viable alternative. Doing away with conventional springs allows for a much smoother ride, something you can’t get with metal springs. After all, you are - quite literally - floating on a cushion of air!
Flexibility
With an onboard air-supply system, you can adjust the suspension with the flip of a switch. If a heavy load has the rear end of your truck squatting lower than usual, the height-control valve (part of the ECAS*) will keep the load level and stable.
*The Electronically Controlled Air Suspension also features height sensors (height-control valves) used to automatically control the vehicle's ride height.
The Cons: What are the downsides to airbag suspension?
Installation
The biggest drawback of an air bag suspension has always been installation. Fortunately, the newer air suspension kits have reduced the need for cutting and drilling. However, you will need to drill holes to mount the compressor, manifold and tank. If you own a car or light-duty truck, there’s going to be problems with space, not to mention the noise factor whenever the compressor decides to kick in.
Expense
If you want the smooth ride that air bags offer, you’re going to have to pay for it. Without including labour, you’ll be looking at a couple thousand dollars. If you decide to install it yourself to save on labor costs, there are quite a few components in the box. If you’re not a gear head, the task is probably above your pay grade.
Reliability
Airbags take a pounding. Unless they’re high-quality, they will eventually leak. If they burst on a road trip, it could compromise your brakes, reduce control of your vehicle and lead to an accident.
Maintenance
You need to think twice about using an air bag on your vehicle if you’re the type to ‘set it and forget it’. This complex system is expensive and needs plenty of TLC! Regular checkups are imperative in order to protect your investment.
What is a Timbren SES suspension upgrade?
Timbren Industries is a Canadian company located in Whitby, Ontario. Timbren specializes in suspension upgrades for trucks, vans, SUVs, and trailers. Instead of using airbags, Timbren’s line of SES (suspension enhancement system) products are based on Aeon® hollow rubber spring technology. We’re talking about airbags with no air!
Timbren Industries first introduced the North American market to Aeon® hollow rubber springs as the alternative to airbag suspensions. Timbren SES suspension upgrades fit virtually every truck, van, and SUV that rolls off the assembly line. To date, there are over 400 SES kits available to the North American consumer.
Much like an airbag system, Timbren SES products replace the existing bump stops. But unlike an airbag system, Timbren SES suspension upgrades don’t depend on compressed air to enhance the ride. In fact, they’re an alternative to air ride. Aeon® hollow rubber springs are made of natural rubber engineered to lift the vehicle without the use of compressed air.
If you have a few common tools and know how to remove a bump stop, Timbren SES upgrades are easy to install. The basic components of an average SES suspension kit explain why:
- 2 Aeon® springs
The average SES suspension upgrade runs about $300.00 US. There are no additional features to purchase.
Airbagman or Timbren SES: Which suspension upgrade is best for you?
If money is no object, you might want to consider an air ride suspension. But at the end of the day, you’re riding on a rubber bag filled with air. If something goes wrong with this high-maintenance system, you’ll need to spend more money to get it fixed.
However, a Timbren SES upgrade does not need air to make it work. Therefore, it requires zero maintenance and remains completely bulletproof.
Additionally, an airbag system doesn’t provide enough stability if you’re hauling a top-heavy load like a truck camper or towing a heavy 5th Wheel. You will be pleased to know that Timbren SES upgrades can handle even the heaviest loads.
“Whether we’re towing with our Nissan Titan or our Toyota Tundra, our Timbren SES kit has been a game changer. Reduced all sag in the rear plus helps the tow rigs gain maximum control. Over a year with SES and we would never go back.” @ClicOutdoor
