The Benefits of Adding Air Springs

9/19/2013

Whether you're towing a trailer, hauling heavy equipment, or loading up for a weekend adventure, added weight can put extra demands on your vehicle's suspension. Rear-end sag, bottoming out, and changes in handling can make towing and hauling less comfortable and more challenging.

That's where air helper springs come in.

Also commonly called air bags for trucks or towing, air helper springs work alongside your vehicle's existing suspension to provide adjustable load support. By adding or releasing air pressure, drivers can fine-tune their suspension support to accommodate changing loads.

Here are seven benefits of adding air helper springs to your vehicle.

1. Reduce Vehicle Sag When Towing or Hauling

One of the most noticeable signs that your vehicle is carrying a heavy load is rear-end sag, sometimes called squat.

2. Help Maintain Steering and Braking Performance

Heavy loads can change your vehicle's stance and affect how it handles on the road.

When the rear of a vehicle sags significantly, the change in ride height can affect steering feel and vehicle handling. Air helper springs help maintain a more level vehicle stance, supporting more predictable handling when towing or hauling.

It's important to remember that air springs don't increase your vehicle's braking capacity or weight ratings. Proper loading, weight distribution, and staying within manufacturer specifications remain essential.

3. Help Maintain Proper Headlight Aim

A heavily loaded vehicle doesn't just sit differently. It can also change where your headlights are pointing.

4. Support a More Controlled Towing Experience

Towing a trailer introduces additional forces that can affect how your vehicle feels on the road.

5. Improve Ride Comfort Under Heavy Loads

A vehicle's suspension is designed to balance comfort and load-carrying capability. Adding significant weight can change that balance.

Air helper springs provide supplemental support when your vehicle is loaded, helping reduce excessive suspension compression and improve ride comfort in appropriate conditions.

Because air pressure is adjustable, drivers can tailor the amount of support to the load they're carrying. Using the recommended pressure for your vehicle and air spring system is important, as excessive pressure can create a firmer ride than desired.

6. Help Reduce Body Roll Under Load

Carrying a heavy load, especially one with a higher center of gravity, can affect how much a vehicle leans during turns or other maneuvers.

7. Reduce Bottoming Out

Bottoming out happens when a vehicle's suspension compresses far enough to reach its travel limit, often producing a noticeable jolt.

Heavy cargo, trailer tongue weight, and uneven road surfaces can make bottoming out more likely.

Air helper springs provide additional support to help reduce excessive suspension compression under load. This can make driving over bumps, dips, and uneven surfaces more comfortable while helping the suspension manage added weight.

Are Air Helper Springs Worth It?

If you regularly tow a trailer, haul heavy cargo, or carry loads that cause your vehicle to sag, air helper springs can be a valuable addition to your suspension.

Their biggest advantage is adjustability. Unlike fixed suspension modifications, air helper springs allow drivers to change the amount of support based on what they're carrying.

Keep in mind that air helper springs do not increase your vehicle's manufacturer-rated towing capacity, payload capacity, or gross vehicle weight rating (GVWR).

From reducing rear-end sag and bottoming out to helping maintain ride height and comfort under load, air helper springs offer a practical solution for drivers whose towing and hauling needs change.

Find the Right Air Springs for Your Vehicle

Air Lift offers a range of adjustable air helper spring systems designed for different vehicles and load-support needs.

Whether you're towing a camper, hauling work equipment, or carrying extra cargo, finding the right air spring kit starts with your vehicle and how you use it.

Truck squat before and after Air Lift

When additional weight from cargo or trailer tongue weight pushes down on the rear suspension, the vehicle may sit lower in the back than it normally would.

Air helper springs provide adjustable support to help reduce sag and maintain a more level ride height under load. Whether you're towing a camper, hauling equipment, or carrying supplies in your truck bed, adjusting air spring pressure helps you accommodate the weight you're carrying.

When the rear suspension compresses under a heavy load, the front of the vehicle may rise, causing headlights to aim higher than intended. This can reduce visibility on the road ahead and create glare for oncoming drivers.

By helping maintain a more level ride height, air helper springs can help reduce load-related changes in headlight aim.

Crosswinds, passing vehicles, uneven road surfaces, and shifting loads can all influence the towing experience.

Air helper springs provide adjustable rear suspension support to help manage the effects of added weight and maintain a more consistent vehicle stance.

load distribution

Air helper springs add adjustable support to the existing suspension, helping manage load-related body movement and maintain a more controlled feel.

The amount of improvement depends on the vehicle, load, suspension setup, and air spring pressure. Proper loading and safe driving practices remain essential.
