Air Suspension vs. Coil Springs: A Brief Overview

Air suspension vs coil springs is a hot issue in the transportation world. When purchasing spare parts for a freight vehicle, make sure that you are purchasing the right ones because every dime you spend, counts. 

So, the question arises, which one should you choose?

If this is a question you’ve been wondering about, this blog will provide satisfactory answers. It will go over each option and explain which of the two is the better choice and why. So, without further ado, let’s dive deep into this topic.

When selecting a suspension system, keep in mind that it should make the ride as smooth as possible. A good system insulates the driver and the vehicle from constant vibrations and bumps. When the tires make contact with the road, the cargo should be protected from the shocks.

Nowadays, air and spring suspensions are the most commonly used options in the transportation industry. If you’re not using one, you’re most likely using the other. However, as explained below, there is a difference in how they work.

Air suspension

When the trailer strikes the bottom hard, the air is trapped in spring bags and acts as a cushion. Air suspensions work in a similar way that air is used in braking systems. The air effect is made of a special rubber that undertakes the same function as metal springs.

Spring Suspension

It is an elongated and slim metal strip system. The strips are bound together to form a unit, which is known as a leaf pack. They are strategically placed directly above the axle and absorb ground shocks before they reach the cabin and the rest of the trailer.

Spring Ride vs. Air Ride

In a test of both spring and air suspension, it was revealed that metal springs provide a smoother ride than air ones. This is especially true at the trailer’s rear end. As a result, when choosing between the two, you may need to take such studies into account.

The Verdict

Spring suspension is the winner here. Apart from protecting and ensuring a smooth ride, spring suspension has additional benefits. Springs will require less upkeep. In fact, springs are more likely to last for the trailer’s lifetime. You won’t have to replace them after every trip.

Air suspension may be equally effective at protecting and guarding the entire trailer, but it necessitates ongoing maintenance. You should inspect them for any punctures on a regular basis. When they fail (which they frequently do), you will waste money and time for the client. Another disadvantage of the air system is the high cost of installation. The air suspension system will cost more money to install. To be fair, saying that air suspension is superior to spring suspension is incorrect.
