Best Air Bag Suspension
A traditional automobile suspension system is comprised of components such as linkages, tires, shock absorbers and springs working together to maintain a vehicle’s ride quality and handling. It is also used to control a vehicle’s ability to load additional weight in relation to these factors. Conventionally, a suspension system utilizes springs that are manufactured with the use of steel as the main material. A compressor is used to replace the steel springs in an air suspension system. This compressor pumps air to the air springs to raise and lower the vehicle’s chassis from its axle. The main concept behind this is the rule that a car’s only points of contact with the road is through its tires. Air suspension is known as “air bag suspension” when it is sold as an aftermarket enhancement.

Firestone 6781 Ride-Rite Rear Air Helper Spring
Made by Firestone, the 6781 Ride-Rite Rear Air Helper Spring weighs 2.9 pounds each. These air helper springs will allow you to support loads up to 5000 pounds per pair. As weight is loaded into the vehicle, the stock suspension system is compressed to accommodate the additional pressure. This results in a change to the vehicles ride height and handling. The air helper springs reduces the strain to the suspension with the use of air pressure. This allows the springs to compensate for the additional weight.
Upon full installation and inflating the air springs, they should be inspected visually to make sure that they are properly aligned. You should check the distance between the upper and lower brackets to determine if the ideal height of vehicle operation is met. The individual air springs have independent inflation valves to equalize the air pressure for each spring. It is not uncommon to have pressure differential among the air springs as the ride height is affected by the gross weight of the vehicle’s frame.
It is recommended that you inflate the air springs up to 50 psi. Loss of pressure is to be expected, but should not exceed 4 psi per week. Inspect the brackets periodically, especially if you have recently loaded a significant amount of weight onto your vehicle.
Firestone Double Convoluted Air Spring – 267C1.5 Style – 1/4 NPT
This air spring is designed to operate at 100 psi, offering maximum weight support through a 4-layer reinforcement construction. Braided wire girdle hoops allow for the creation of convoluted shape, increasing the spring’s capabilities to support additional loads. Double convoluted air springs also have additional spring rate, making it suitable for long-distance travels at maximum load capacity. Designed to keep a secure connection between the air bags and the end plates, it is made from environment friendly materials to deter corrosion and damage.
The springs are designed for a ride height of a maximum of 8.3 inches and a compressed height of 2.8 inches. This gives maximum cushioning between the vehicles components, particularly the brackets and the frame, as well as providing maximum ride comfort and performance. The 267C1.5 can support up to 4800 pounds, per pair, with a ride height of 5.5-6.5 inches.
The brackets should be inspected periodically for air pressure loss and damage. Accumulated debris such as dirt, sand, and gravel should be washed away after rugged use to prevent puncture and general wear-and-tear. The air pressure should also be checked every week, with normal loss of 3-4 psi per week. Never exceed 100 psi when inflating your air springs.

Cars with Air bag Suspension
Air suspension is a feature found in flagship models of luxury car manufacturers. High-end vehicles with air suspension offer a gliding ride quality that corrects irregularities when a car comes into contact with the road. Air suspension entails adjusting the ground clearance, air pressure, and ride height of a vehicle automatically. This system is controlled by a complicated arrangement of sensors, electronics, and computers. Most of these developments have been engineered in-house by some of the world’s preeminent car companies through years of research and innovation. This feature significantly adds cost to production; hence it is generally reserved for top shelf models that can be sold at a premium.
A major drawback to air suspension is the cost of maintaining it. Since the system replaces steel with rubber, it is not uncommon for these components to deteriorate or be damaged much faster than its traditional counterparts. Several factors include general wear-and-tear, punctures, and condensation.
Air suspension is also added to some SUV’s to increase the amount of weight that it can carry. However, this feature makes the vehicle’s air bag suspension susceptible to friction caused by its contact to the chassis as a result of the additional weight. This results to air-line failure through gradual use over time, and must be checked at regular intervals.
Rear Suspension Air Bags
Rear suspension air bags are used to fit in the rear end frame of a truck or an SUV. They are designed to work in conjunction with standard leaf spring mounts to prevent the vehicle from sagging. Installing rear application kits results to reduced “bottoming out” and tire wear. The system works by lifting the rear end away from the frame by inflating the bags when carrying additional weight. Before installing rear suspension air bags, the frame of the vehicle must be braced and leveled. This is done by removing the frame from the vehicle and welding the components from the outside.
