99 ProSeries Load Support Systems: Installer-Exclusive Performance for Towing and Hauling
3/10/2026
When vehicles are pushed beyond everyday driving, through towing, hauling, and demanding work applications, maintaining proper ride height and stability becomes critical. Rear-end squat, sway, and loss of control are common issues when factory suspension components are asked to manage heavy loads.
The 99 ProSeries load support systems from Air Lift Company are engineered to address these challenges with professional-grade performance and installer-exclusive quality. Designed for vehicles that work hard, 99 ProSeries delivers dependable load support that helps improve control, safety, and confidence under load.
What Makes 99 ProSeries Different
99 ProSeries is available exclusively through authorized Air Lift installers and upfitters. This installer-only distribution model ensures proper application, professional installation, and consistent performance, elements that are critical for load support systems designed for towing and hauling.
By removing 99 ProSeries from online and retail channels, Air Lift is able to focus on delivering a premium product experience built around correct fitment, proper setup, and long-term reliability.
Built to Reduce Squat and Improve Stability
At its core, 99 ProSeries is designed to help vehicles remain level and stable when weight is added. By providing additional support under load, the system helps reduce common towing and hauling issues such as:
- Rear-end squat and sag
- Trailer sway and excessive body roll
- Bottoming out under heavy loads
- Poor headlight aim and reduced steering control
The result is a more balanced, predictable driving experience, whether towing a trailer, hauling equipment, or carrying consistent payloads.
Adjustable Support for Real-World Loads
Towing and hauling demands can change from day to day. 99 ProSeries load support systems are fully adjustable, allowing support to be tailored to different load conditions while continuing to work in harmony with the vehicle’s factory suspension.
This adjustability helps maintain ride quality when unloaded, while providing the additional support needed when the vehicle is working at its limits.
Engineered for Professional Installation
99 ProSeries was designed with installers in mind. The bolt-on design requires no frame drilling and can be installed using common shop tools, helping streamline installation while maintaining a clean, professional result.
Compatibility with most fifth-wheel and gooseneck hitches makes 99 ProSeries a practical solution for a wide range of towing setups and work-truck applications.
Proven Engineering Backed by Air Lift
With more than 75 years of suspension expertise, Air Lift applies rigorous testing and proven engineering to every ProSeries product. Key components are validated through extensive cycle testing to ensure durability and long-term performance in demanding environments.
Every 99 ProSeries system is supported by Air Lift’s Limited Lifetime Warranty, 60-Day Ride Satisfaction Guarantee, and dedicated in-house customer service team, providing confidence for installers and vehicle owners alike.
A New Standard in Professional Load Support
The launch of 99 ProSeries represents Air Lift’s commitment to delivering installer-exclusive, professional-grade load support solutions. Built for towing, hauling, and real-world work, 99 ProSeries helps drivers maintain control, stability, and confidence when it matters most.
