We recently posted a story about the basics of lowering trucks and thought it was fitting to go beyond by explaining how some trucks are able to sit flat on the ground. Many of the vehicles we’ve featured on this page are so low that some people think they don’t function. That is a bit true as they can’t really drive like that, but with the help of an adjustable suspension system, these vehicles can lay low when parked and raise up to move around.

Although adjusting the height of a vehicle was popularized with the introduction of hydraulics on lowriders, truck enthusiasts prefer airbags. In the lowrider scene, hydraulic suspensions are a quick way to make a car go up and down and even hop on command. Well, custom trucks are more about cruising low than getting airborne and airbags are a better way of getting there.

These systems use compressed air to inflate rubber "bags" that replace conventional springs, which have a fixed height. To drop a vehicle with this setup, the air is released from the system and the bag deflates to compress the suspension. Airbags also provide a smoother ride as long as they are used in combination with shock absorbers to prevent a vehicle from bouncing vigorously. They can be also be very reliable as long as they are mounted away from hot components like an exhaust and sharp objects that might puncture them.

1. Airbags

Here is what a typical airbag looks like with a rubber bellows implemented for adjustability. Slam Specialties is one of the leading airbag providers and this example shows the solid upper and lower parts that are used for mounting locations. There is a port located up top so it can be plumbed for its supply of compressed air.

A variation to traditional airbags is the ShockWave produced by the folks at Ridetech. These are a great way to simplify installation as the airbag is integrated with a tuned shock. Though they are limited on how much height adjustment they provide versus regular airbags, ShockWaves hold up better for vehicles with high performance engines.

2. Accessories

Airbags require compressed air in order to function and that means there are a few other parts that must be installed along with them. They need a steady supply of air from a reserve and most people use single or dual 5-gallon tanks to meet the demands of a system. Filling the tanks is done with compressors and it’s a good idea to incorporate water traps to prevent corrosion from condensation that may develop.

To regulate airflow to the bags, a set of valves are required, which will need to be managed by a pressure monitoring system or a controller like the Slam Specialties MC.2. These accessories are available from many distributors like AVS, Lowrider Depot and Switch Suspension.

3. Integration

The easiest way to swap in a set of airbags is to purchase or fabricate mounting equipment. If you have a coil front suspension, the springs can be removed to allow for an airbag to go in. The preferred method for a rear suspension is to add a multi-link system.

For older trucks that are a bit more difficult to modify, there are companies like Porterbuilt that offer complete front and rear kits. These products are easy enough for the DIY builder to install in a garage or driveway with a minimal number of tools. They are also better designed for tucking large wheels and providing modern drivability.

4. Full Chassis

A common problem for those working on classic trucks is rust and worn out pieces. Also, old frame rails were never designed to handle modern components and are usually tired. To really get the most out of a truck, a new chassis will get it there. Most of the offerings come with all modern components including rack and pinion steering for a better driving experience.

Though there are many options when ordering a full chassis, these systems are designed to bolt up to existing mounting points on specific bodies. Making the switch takes a bit of labor but there is very little guess work with a new chassis. Some of our recommended chassis builders include GSI Machine and Fabrication, the Roadster Shop and Scott’s Hotrods ‘n Customs.

5. Body Modifications

The latest trend in slammed trucks is to add air suspensions along with 20-inch plus wheel and tire combos. Since trucks were not originally intended to tuck large rolling stock, truck bodies usually have to be modified. Yes, the inner fenders can simply be cut open to make room for them, but open spaces will lead to road grime getting flung everywhere.

For those that have metal working skills, trailer fenders can be used to make new inner fenders to cover openings. There are also companies like Slosh Tubz, which make prefabricated pieces to fill the void. They can also be finished off to compliment the rest of the vehicle. Once installed, an airbagged vehicle can look good rolling and shock all when completely slammed on the ground.

Key insights

• Airbags are mandatory in all states of our country for all drivers and manufacturing companies.
• It is also the duty of the driver to keep a regular check on the airbags.
• There are different types of airbags as per their role and requirements.
• The cost of airbags repair and replacement is high because of the material they are made of and the safety they provide.

There are some accidents that are out of our control like someone colliding with our vehicle intentionally or unintentionally. But our safety and protection are in our control. With advancements in the automobile industry, car manufacturing companies are adding several new devices and gears to increase the safety of drivers and passengers. One of these safety gears that has become a necessity is the AirBag.

Do you know? Airbags reduce driver fatalities by 29% in case of frontal crashes. Airbags are one of the most important elements for the safety of drivers and passengers in any car anywhere around the globe. The major advantage of airbags is they protect you from major physical injuries in a road accident. Most of the state and central governments have made it mandatory for manufacturing companies to add high-quality airbags in the cars, especially on both front seats.

This blog is written with an objective to cover everything that a driver needs to know about airbags.

History of Airbags

We found the origin of airbags under a patent by two dentists Birmingham, Arthur Parrott & Harold Round. This was for covering airplanes as well as parts of other vehicles. But if we talk about cars; then the first patent was filed by John W. Hetrick in .

The first automobile company that adopted airbags was Ford. In the early ’s Ford car models had the basic version of airbags. Just after that General motors also started adding airbags to the government fleet purchased. Both Ford and General motors lept working on the idea of adding and removing airbags and finally claimed that the airbags are unfeasible and inappropriate.

Chrysler was the first company in to make airbags a standard requirement in all of its models in the driver side at least. Still, the drivers and manufacturing companies did not accept airbags until the early s.

How do airbags work?

Airbags are inflatable cushions that save the life of a driver by protecting him or her from hitting interior objects in the car or even exterior objects like a tree or another vehicle in case of an accident.

Whenever your vehicle collides with another vehicle of the object the sensors in your car detect the severity of the collision. If the crash is severe enough then the sensors will signal the inflators to fill the airbags with gas as quickly as possible.

Airbags don’t require any maintenance until they are used in an accident. If they are used even once in a crash then they must be replaced at any repair shop. Make sure the repair shop uses Original Equipment Manufacturer (OEM) parts for replacement.

What are Airbags made of?

Airbags are made of an air cushion restraint system or inflatable restraint system and consist of two parts; the airbag module and the inflator unit.

The airbag modules are made of thin, woven nylon fabric. The inflator unit consists of a small canister housing, along with an igniter, and a chemical propellant. At the time of an accident, the chemical propellant undergoes a controlled reaction that produces nitrogen gas, which results in inflation of the airbag.

There is a powdery substance also released at the time of airbag inflation. Most of the time it is either a talcum powder or cornstarch powder to keep the airbags lubricated and maintain their elasticity.

Types of Airbags

Airbags are also of different types and are added to the different areas of the car to save the driver’s different body parts. To help you understand everything about airbags and how they will protect you in case of an accident it is important to understand the types.

1. Driver’s Front Airbag
2. Driver’s Knee Airbag
3. Passenger’s Front Airbag
4. Side Airbags
5. Curtain Airbags

Front Airbags:

Frontal airbags have become a standard necessity for all passenger cars since . It is also mandatory in all vans and SUVs since . These airbags are mounted under the steering wheel of the car to protect the driver.

For the passenger side, frontal airbags are under the dashboard. Most of the front airbags work with seatbelt sensors to check if the driver and passengers are wearing seatbelts or not. Some of the modern cars have a front seat weight sensor to check if a young or small person is sitting on the front seat.

Side Airbags:

Side airbags protect the driver in case the car collides sideways, especially the head and chest area of the driver. Our head is always next to the window and in case of an accident, there are high chances that the head will collide with the window with high intensity. This is when the side airbag cushion comes into the picture.

Side airbags are not mandatory for the manufacturing companies and the drivers but they are recommended for everyone to improve the safety standards.

Knee Airbags:

Just like side airbags; knee airbags are for the protection of your knees in case of an accident. Whenever our car collides with any other car or objects our knees are at high risk of fractures because of the objects and dashboard.

In such cases, knee airbags play an important role by inflating the air cushions between the leg and dashboard. These are placed under the steering wheel of the car near the knees of the driver. And in the case of passengers, these airbags are present under the glove compartment.

Inflatable Seat Belt:

This is a modern airbag which is available in only the selected models of cars. Instead of protecting from injuries during an accident; inflatable seat belts help in spreading the force of the accident over a wider area all over the body of the driver.

When the impact is not concentrated then the injuries are not much severe hence fewer chances of fatality in case of a severe accident or collision.

16 Common Types Of Airbag Injuries

Airbags can cause multiple injuries to the drivers as they are quick to open and with high force. Following is the list of some common injuries drivers and passengers can get because of airbags:

1. Rib fractures
2. Hearing Loss
3. Traumatic brain injury
4. In the case of pregnant women; injured to the fetus
5. Impact burns
6. Facial contusions
7. Internal organs damage
8. Lacerations
9. Abrasions
10. Chemical burns
11. Asthma attacks
12. Pulmonary and cardiac complications
13. Strains or trauma to the neck or back
14. Internal bleeding
15. Organ failure
16. Eye injuries, like retinal tear or detachment

Now that we know there are chances of getting injured by airbags; we need to know ways to protect ourselves:

How to prevent injuries from airbag?

1. Always wear your seatbelt
   Seatbelts get tightened during accidents hence preventing the driver and passenger from face injuries due to airbags. Most of the face injuries occur due when the face is too close to the area where seatbelts deploy.
2. Try to sit far away from the steering if practically possible
   To protect yourself from airbags injury it is important to give airbags the space they need to inflate and get out of their way. The best way for this is by sitting far away from the steering wheel.
3. Avoid driving while pregnant
   There are high chances of your fetus getting hurt in an accident especially during the last few months of the pregnancy.
4. Don’t lean against the door
   In case of an accident, drivers tend to lean against the door as a reflexive action to get out of the car. But if your car has side airbags then it can cause severe injuries to your head and neck.

Conclusion

Airbags have saved more than 50,000 lives between to and this is actually enough to convince drivers about the importance of airbags. Even though most of the modern cars are coming with all the different types of airbags needed for the protection of drivers and passengers.
