Air helper springs (airbags) vs full suspension : which is the best option for your truck?
A complete comparison for pickup trucks, overlanding, and towing
When looking to improve the handling of a loaded truck—whether it’s for a camper, towing, off-road driving, or carrying a constant load—two solutions often come up: air helper springs (airbags) and full suspension systems.
In this article, we explain the differences, advantages, and limitations of each option, and when to choose one over the other—so you can make the best decision for your needs.
What is an air helper spring (airbag)?
Air helper springs are air-filled cushions installed between the axle and the vehicle’s frame. Their main purpose is to prevent rear sag in a truck when it is carrying a load.
Advantages of air helper springs
- An affordable option for managing load
- Quick and minimally invasive installation
- Adjustable based on the load being carried
- Ideal for occasional towing or variable loads
Limitations to be aware of
- Do not improve ride comfort or handling
- Not recommended for off-road use (they limit suspension travel)
- Do not replace a suspension designed for constant load carrying
- Risk of air leaks or the need for regular maintenance
What is a full suspension system?
It is a system made up of shocks, springs (often progressive), and sometimes an upper control arm (UCA) to correct suspension geometry, especially in lifted setups.
Advantages of a full suspension system
- Significantly improved comfort on and off the road
- Ideal support for constant loads (camper, rack, bumpers, overland equipment)
- Improved stability, reduced body roll, and better cornering performance
- Increased suspension travel for off-road use
- Increased component durability
Limitations of a full suspension system
- Higher cost than air helper springs
- Spring selection is important depending on the load
- More complex installation
Which option should you choose based on your use case?
Choose air helper springs if:
- You do occasional towing
- You carry a non-permanent load
- Your goal is simply to level the rear of the vehicle
Choose a full suspension system if:
- Your truck carries a permanent load (Four Wheel Camper, GFC, Alu-Cab, rack, bumpers, drawers, etc.)
- You want improved comfort and better control
- You drive off-road or on rough roads
- You are looking for a durable and high-performance solution
Conclusion: which is the best option?
There is no one-size-fits-all solution, but rather a choice that depends on your use case.
- Variable load → Air helper springs
- Constant load + performance → Full suspension system
