The Air Lift LoadLifter 5000 is a suspension support system designed to improve vehicle handling and stability, particularly when carrying or towing loads. This article details the installation process, functionality, and considerations for this system, based on available documentation. The system is applicable to vehicles such as the Ford Transit, and offers both basic air spring installation and options for onboard compressor integration. Air Lift Company has been in operation since 1949 and offers a standard limited lifetime warranty on its air springs.
System Components and Functionality
The Air Lift LoadLifter 5000 kit provides additional support to a vehicle’s existing suspension system. This support is adjustable, allowing users to modify the stiffness of the suspension based on payload requirements. The system does not increase the vehicle’s overall payload capacity or ground clearance. It functions by providing adjustable air pressure within air springs, which counteract the effects of increased or decreased weight.
The system offers two primary installation approaches: installation of the air springs alone, or installation of the air springs in conjunction with an onboard air compressor. If only the air springs are installed, an external compressor or bicycle pump is required to adjust air pressure. Installation of the Air Lift 72000 Wireless Air Leveling Compressor allows for on-the-fly pressure adjustments via a wireless remote. This compressor includes a manifold that enables independent pressure adjustment for each air spring, allowing for fine-tuning and vehicle leveling.
Installation Procedure – Air Springs
The installation process requires raising the vehicle to access the suspension components. The documentation specifically references the Ford Transit, noting the location of the jack and tools. Safety precautions, such as activating the handbrake and using wheel chocks, are recommended. The factory jounce bumper must be removed to accommodate the air spring installation. The LoadLifter 5000 Ultimate kit includes internal jounce bumpers to replace the factory units, providing protection in the event of air spring failure.
The installation steps, as outlined in the Air Lift Load Lifter 5000 Ultimate Kit #88213 Installation Manual, involve:
- Raising the vehicle body.
- Removing the factory jounce bumper.
- Installing the upper frame bracket, securing it with carriage bolts and a button head screw.
- Pre-assembling the air spring with the lower roll plate, lower bracket, and carriage bolts.
- Installing the assembled air spring onto the vehicle. The documentation notes that the air spring may initially be difficult to fit and suggests compressing the spring to facilitate installation.
- Following the installation manual for torque specifications and final assembly steps.
The documentation suggests applying 3M anti-erosion tape to protect against rubbing on the passenger side.
Installation Procedure – Onboard Compressor
Installation of the Air Lift 72000 Wireless Air Leveling Compressor involves additional steps. The compressor and manifold must be mounted in a location protected from direct water splash, though they are water-resistant, not waterproof. Air Lift provides resources with recommended compressor locations based on vehicle make and model.
The installation steps include:
- Deciding on a mounting location for the compressor and manifold.
- Mounting the compressor and manifold.
- Following the installation manual for detailed instructions and torque specifications.
System Benefits and Considerations
The Air Lift LoadLifter 5000 system offers several benefits:
- Improved Weight Distribution: The system helps distribute weight evenly across all four tires.
- Enhanced Ride Comfort and Safety: Proper weight distribution improves ride comfort and enhances safety.
- Reduced Sag: The increased stiffness reduces vehicle sag when cornering.
- Leveling Capability: The system can level the vehicle for overnight parking.
- Independent Air Spring Control: With the onboard compressor, independent pressure adjustment for each air spring allows for fine-tuning and vehicle “rolling.”
It is important to note that the system does not increase the vehicle’s payload capacity or ground clearance. The “Ultimate” kit includes internal jounce bumpers for added safety in case of air spring failure. A heat shield should be installed on the passenger side during installation.
Cost and Time Investment
According to one source, the total cost of the installation, including components, is approximately $850 USD. The estimated time required for the installation is 10 hours, although this may be reduced with prior experience.
Warranty Information
Air Lift Company provides a 60-day, money-back guarantee and a no-risk ride satisfaction guarantee. The air springs are covered by a standard limited lifetime warranty with no mileage restriction.
Conclusion
The Air Lift LoadLifter 5000 is a suspension enhancement system designed to improve vehicle handling and stability under varying load conditions. Installation involves replacing the factory jounce bumpers and mounting air springs to the vehicle’s frame and axle. The addition of an onboard compressor provides convenient on-the-fly pressure adjustments. While the system does not increase payload capacity, it offers benefits such as improved weight distribution, enhanced ride comfort, and leveling capabilities. Proper installation, following the provided manual, is crucial for optimal performance and safety.
