Which Is Better: Airbag or Spring Suspension?

Author: Toby   Date Posted:24 January 2025 

 

When it comes to choosing suspension systems for your vehicle, particularly if you’re considering an upgrade, two popular options often come up: airbag suspension and spring suspension. Both systems aim to enhance ride quality and vehicle handling, but they operate quite differently. Airbag suspension, in particular, has seen a significant rise in popularity, with the global automotive air suspension market valued at USD 6.72 billion in 2023. This market is projected to grow to USD 11.96 billion by 2032, with a compound annual growth rate (CAGR) of 6.8%.

So, which one is better? Let’s break it down so you can make an informed choice for your car, 4x4, or performance vehicle.

 

What Is Airbag Suspension?

Airbag suspension (also known as air suspension) uses compressed air to support the weight of your vehicle. Airbags, made from strong rubber or fabric, inflate or deflate to adjust the ride height and firmness. This system is popular in both passenger vehicles and 4x4s due to its adjustable nature.

Key Benefits of Airbag Suspension Drawbacks of Airbag Suspension
  • Adjustable Ride Height - You can raise or lower your vehicle depending on your needs. This is particularly useful if you’re towing, off-roading, or carrying heavy loads.
  • Smooth Ride - Air suspension systems provide a smoother ride by absorbing bumps and irregularities in the road better than traditional springs.
  • Load Levelling - The system automatically adjusts to maintain a level ride, which is especially beneficial when carrying heavy loads or towing.
  • More Expensive - Air suspension kits are generally pricier than traditional spring systems, both in terms of initial cost and maintenance.
  • Complexity - With all the air compressors, valves, and sensors, airbag suspension systems can be more complex to install and repair.
  • Less Durability - While the system is excellent for comfort, airbags can sometimes be less durable than springs, particularly in harsh conditions or extreme temperatures.

 

What Is Spring Suspension?

Spring suspension is the traditional and most common type of suspension system used in vehicles. This setup relies on steel or other materials to create coils (or leaf springs in older systems) that absorb shocks when the vehicle encounters bumps, dips, or uneven surfaces.

Key Benefits of Spring Suspension Drawbacks of Spring Suspension
  • Affordable - Springs are far less expensive than air suspension systems, both in terms of the initial cost and long-term upkeep.
  • Durability - Steel springs are highly durable and less likely to experience issues like airbag failure. They are more resilient to wear and tear and weather conditions.
  • Simplicity - A spring suspension system is relatively simple to install and maintain, making it a go-to choice for many vehicles, including 4x4s and performance cars.
  • Limited Adjustability - Unlike airbag suspension, springs do not offer height adjustment. You’re stuck with the ride height that your vehicle is designed for, which may be less than ideal for off-road use or towing.
  • Stiffer Ride - While modern spring systems are designed for comfort, they can’t match the smoothness of air suspension. Larger bumps and rough terrains might be more noticeable.
  • No Automatic Load Levelling - Unlike air suspension, springs don’t automatically adjust to the load of the vehicle. This means you may need to manually adjust or replace your suspension components if you're carrying heavy loads frequently.

 

Airbag Suspension vs. Spring Suspension: Which Is Better?

Now that we’ve outlined the pros and cons of each, let’s compare them head-to-head based on common use cases. The decision ultimately depends on your vehicle’s needs, budget, and personal preferences.

1. For Comfort

If comfort and a smooth, adjustable ride are your top priority, airbag suspension is the way to go. Airbags absorb bumps better and provide a softer ride, especially for vehicles that deal with rough roads or uneven terrain.

2. For Off-Roading

Airbag suspension is great for off-road vehicles because it allows you to adjust the ride height to suit different terrains. If you're heading into rugged areas or need more ground clearance for obstacles, air suspension gives you the flexibility to raise your vehicle. However, if you’re into hard-core off-roading with a focus on durability, springs might be a better choice, as they’re less prone to damage.

3. For Towing and Heavy Loads

Both systems perform well when it comes to towing, but airbag suspension has the upper hand. It automatically adjusts to maintain a level ride, making it ideal for carrying heavy loads or towing. Spring suspension, on the other hand, is not as flexible in this area, and you may need to replace or upgrade components for better load management.

4. For Cost Efficiency

If you're on a budget, traditional spring suspension is the more cost-effective option. It’s less expensive to purchase and maintain. Airbag suspension requires a larger investment upfront, and repair costs can be higher if something goes wrong with the air compressor or the airbags themselves.

5. For Durability

Spring suspension is built to last. Steel springs are tough and require minimal maintenance. Airbag suspension, while offering superior comfort and adjustability, may not be as long-lasting, especially in harsh conditions. However, it can still last a good number of years with proper care.

 

Choosing the Right Suspension with Superspares

So, which is better: airbag suspension or spring suspension? It depends on your needs and how you plan to use your vehicle.

  • If you’re looking for comfort and adjustability, airbag suspension offers a smoother, more adaptable ride.
  • If you need durability and cost-effectiveness, spring suspension will keep your vehicle running reliably for years to come.

For those who use their cars or 4x4s for heavy towing, off-roading, or carrying large loads, airbag suspension kits can be an excellent upgrade. However, if you’re after a simpler and more budget-friendly option, spring suspension is the tried-and-true choice.
