What’s Included?
The kit includes:
- Two rear air spring bags
- Mounting hardware (varies by package)
- Air bag assemblies
An onboard air compressor, tank, air management system, or wireless controller is not included unless specifically stated by the retailer.
7,500-Pound Load-Leveling Capacity
Each air spring is rated to support up to 3,750 pounds, providing a combined 7,500-pound load-leveling capacity.
It’s important to understand that this rating does not increase your truck’s Gross Vehicle Weight Rating (GVWR) or towing capacity. Instead, the air bags help support the factory suspension by reducing rear-end squat and improving stability when carrying heavy loads.
Benefits include:
- Better load distribution
- Reduced suspension sag
- Improved vehicle stability
- More consistent ride height
- Better towing confidence
Always stay within the manufacturer’s payload and towing limits.
Adjustable Air Pressure (5–100 PSI)
The helper springs can be inflated anywhere from 5 PSI to 100 PSI, allowing you to tailor suspension support to your current load.
Lower pressures are suitable for unloaded driving, while higher pressures can provide additional support when towing or hauling heavier cargo. Always follow the manufacturer’s recommended inflation guidelines.
Heavy-Duty Rubber Construction
The air springs are constructed from durable rubber reinforced for repeated compression cycles.
Benefits include:
- Resistance to cracking
- Flexible operation
- Consistent load support
- Long service life
- Improved ride comfort over varying road conditions
The kit also uses steel mounting components to help ensure secure installation.
Improved Towing Stability
One of the biggest advantages of rear air helper springs is improved towing performance.
Potential benefits include:
- Reduced trailer-induced squat
- Better steering response
- Improved braking balance
- More consistent headlight aim
- Increased driver confidence when towing
These improvements come from maintaining a more level suspension rather than increasing the truck’s towing capacity.
Direct Bolt-On Installation
The FLOVENTIS kit is designed as a direct replacement that mounts to the factory suspension without major modifications.
Installation features include:
- Vehicle-specific brackets
- Bolt-on design
- No welding required (on most applications)
- Compatible with factory suspension
While experienced DIY mechanics may be able to install the kit, professional installation is recommended if you’re unfamiliar with suspension work or air line routing.
