1. Firestone Ride-Rite: Best Overall
The Firestone Ride-Rite air springs are a popular choice for towing enthusiasts, offering robust load-leveling support for heavy trailers. In our evaluation based on owner feedback and the spec sheets, these bags consistently provide stable ride quality and reduce sag. The butyl rubber construction resists ozone and weathering, contributing to their longevity.
However, the included nylon air lines may require careful routing to avoid abrasion against sharp edges. Users with extreme off-road use may want to upgrade to braided stainless lines. This kit is ideal for those who tow frequently and want a reliable, time-tested solution.
- Durable butyl rubber air springs with internal jounce bumper
- Includes installation kit with brackets and hardware
- Compatible with most full-size trucks and SUVs
Pros: Proven reliability and long service life; Easy to install with basic tools
Cons: Air lines can be prone to chafing if not routed carefully
2. Air Lift 1000: Best Value
The Air Lift 1000 air springs are designed to fit inside the rear coil springs of many trucks and SUVs, providing a cost-effective way to improve load support. Based on manufacturer specs and owner reviews, they effectively reduce sag and sway when towing moderate loads. The internal jounce bumper acts as a safety stop if air pressure is lost.
That said, these bags have a lower maximum capacity compared to external air springs, making them less suitable for heavy fifth-wheel towing. They are best for light- to medium-duty towing where budget is a primary concern.
- Internal jounce bumper for added safety
- Easy installation inside coil springs
- Includes inflation valves and mounting hardware
Pros: Affordable entry-level upgrade; Simple installation, no drilling required
Cons: Limited capacity for very heavy loads
3. Pacbrake Air Lift 5000: Heavy Duty Pick
The Pacbrake Air Lift 5000 is designed for heavy-duty towing applications, with double convoluted air springs that offer high load capacity and stability. Our research indicates that these bags perform well under extreme loads, reducing sag and improving handling. The corrosion-resistant coating adds durability in salt-belt regions.
However, installation may require drilling and more time compared to simpler kits. Users with limited mechanical experience might find it challenging. This product is best for those who regularly tow heavy loads and prioritize maximum support over ease of installation.
- Double convoluted air springs for high load capacity
- Includes heavy-duty brackets and hardware
- Corrosion-resistant coating on metal parts
Pros: Excellent load support for heavy trailers; Durable construction withstands harsh conditions
Cons: Installation can be complex on some vehicles
4. Timbren SES: No Air Required
The Timbren SES system uses silicone elastomer springs instead of air bags, offering a maintenance-free solution for load leveling. Based on owner feedback, these units engage progressively as load increases, providing support without the need for air pressure adjustments. The bolt-on design simplifies installation.
However, when the vehicle is unloaded, the elastomers can make the ride feel stiffer over bumps. They are best for users who want a set-and-forget solution and don’t mind a firmer ride when not towing.
- Silicone elastomer bumps replace air bags
- No air lines, compressors, or maintenance
- Bolt-on installation with no drilling
Pros: Zero maintenance after installation; Works immediately without air adjustment
Cons: Ride quality can be harsh when unloaded
5. SumoSprings by SuperSprings: Progressive Support
SumoSprings offer a foam-based progressive spring solution that fits inside the coil springs or replaces bump stops. Our evaluation of manufacturer specs and owner reviews shows they provide a noticeable improvement in reducing sag and sway when towing moderate loads. The micro-cellular urethane material is durable and resistant to weather.
However, they cannot be adjusted for different loads, and their maximum capacity is lower than many air bag systems. They are best for light to medium towing where simplicity and no-maintenance are key.
- Micro-cellular urethane construction
- Progressive engagement for smooth ride
- No air compressor or lines needed
Pros: Easy installation, no air maintenance; Improves stability without harshness
Cons: Lower maximum capacity than air bags
6. Airlift 5000 Ultimate Plus: Premium Build
The Airlift 5000 Ultimate Plus kit comes with a wireless air compressor system that automatically maintains desired pressure, adding convenience for frequent towers. Based on our research, the air springs themselves are robust and capable of handling heavy loads. The integrated system simplifies adjustments.
However, the higher cost and complex installation can be drawbacks. Some owners reported issues with the wireless controller reliability. This product is best for those who want a premium, hands-off air management system and are willing to invest in professional installation.
- Double convoluted air springs with reinforced ends
- Includes wireless air compressor system
- Corrosion-resistant hardware
Pros: High load capacity with integrated air management; Convenient wireless control
Cons: Premium price, not for budget buyers; Complex installation, may require professional help
7. Hellwig Air Springs: Budget Friendly
Hellwig Air Springs offer an affordable option for those needing extra load support without breaking the bank. Our comparison of specs and owner feedback indicates they provide adequate leveling for light to medium towing, but the single convoluted design is less robust than double convoluted alternatives. The limited lifetime warranty adds some peace of mind.
However, some users reported air leaks after a few years, and the brackets may require modification for a perfect fit. This product is best for occasional towers on a tight budget who are comfortable with DIY installation and potential longevity trade-offs.
- Single convoluted air springs
- Includes brackets and inflation lines
- Limited lifetime warranty
Pros: Low cost entry into air spring support; Decent load capacity for the price
Cons: Less durable than premium brands; Installation can be tricky on some models
Frequently Asked Questions
Do helper airbags affect ride quality when not towing?
Yes, helper airbags can affect ride quality when the vehicle is unloaded. If you run them at low pressure (around 5-10 psi), most systems have minimal impact on ride comfort. However, some designs like Timbren SES or SumoSprings may cause a firmer ride when unloaded because they are always engaged. Air bag systems with adjustable pressure allow you to deflate them when not towing for a smoother ride.
How much weight can helper airbags support?
The load capacity varies by product. Typical helper airbags for light trucks can support between 2,000 and 5,000 pounds per pair. However, the actual weight supported depends on the vehicle’s suspension and the air pressure used. Always check the manufacturer’s specifications and do not exceed the vehicle’s Gross Vehicle Weight Rating (GVWR).
Can I install helper airbags myself?
Many helper airbag kits are designed for DIY installation with basic hand tools. Kits that fit inside coil springs or replace bump stops are generally easier. External air spring kits may require drilling and more mechanical skill. If you are not comfortable with suspension work, professional installation is recommended to ensure proper fit and safety.
Do I need an onboard air compressor for helper airbags?
No, most helper airbag kits come with manual inflation valves that you can fill with a tire pump or air compressor. Some premium kits include an onboard compressor for automatic pressure adjustment, but this is optional. Manual inflation is sufficient for most users, though an onboard compressor adds convenience for frequent adjustments.
Will helper airbags fix trailer sway?
Helper airbags primarily address rear-end sag and improve load leveling, which can indirectly reduce trailer sway by maintaining proper weight distribution. However, they are not a substitute for a properly adjusted weight distribution hitch or anti-sway devices. For severe sway issues, consider a complete hitch setup and ensure proper tongue weight.
Our Verdict
After researching and comparing the top helper airbags for towing, our top pick is the Firestone Ride-Rite for its proven reliability, strong load support, and overall value. For those on a budget or with light towing needs, the Air Lift 1000 offers an excellent balance of cost and performance.
