Frequently Asked Questions
How do I know if the ALF60915 fits my coil springs?
The ALF60915 requires coil springs with a minimum inside diameter of 4.5 inches and a maximum inside length of 7.5 inches. To check, unload your vehicle, allow it to return to normal ride height, and measure the inside diameter and inside height of your coil springs. If your measurements fall within these dimensions, the ALF60915 is your correct Air Lift 1000 universal kit. Air Lift provides a sizing chart at airliftcompany.com to help match measurements to the correct kit number.
What vehicles does the ALF60915 fit?
The ALF60915 is a universal kit that fits any coil-spring vehicle whose springs fall within the 4.5 inch minimum inside diameter and 7.5 inch maximum inside length specifications. This includes a wide range of trucks, SUVs, CUVs, cars, minivans, and motorhomes. Because fitment is based on coil spring measurement rather than vehicle year, make, and model, Air Lift recommends measuring your springs rather than relying on a vehicle application lookup. The kit must be used only with open coil spring suspension designs, not on coilover shock applications.
What PSI should I run in the ALF60915 air springs?
The ALF60915 supports air pressure adjustment from 5 to 35 PSI. At 5 PSI, the air springs provide minimal supplemental support and allow the coil springs to function largely as designed. As load increases, increasing pressure provides progressively more support to level the vehicle and resist sag and sway. Most users adjust pressure based on their current load condition, running lower pressure for unloaded driving and higher pressure when towing or hauling. Do not exceed 35 PSI and do not allow the air springs to run at 0 PSI, as the spring requires minimum pressure to maintain its shape and seal integrity.
Does the ALF60915 replace the factory coil springs?
No. The ALF60915 installs inside the existing factory coil springs, not in place of them. The factory coil springs remain installed and the Air Lift 1000 air spring sits inside the coil, adding supplemental air-adjustable support on top of the factory spring rate. The factory springs handle the base ride quality while the air spring provides the additional load-leveling capacity when needed.
Does the ALF60915 require an onboard air compressor?
No air compressor is included with the ALF60915 kit. The air springs are inflated and deflated through the included Schrader valves using a standard air compressor, portable inflator, or tire inflator. Air Lift offers separate onboard compressor systems (WorkhorseHD, LoadController, etc.) that can be integrated for automatic pressure management, but the basic kit is designed to be inflated manually as needed. Each spring has an individual Schrader valve for independent adjustment.
Is the ALF60915 covered by a warranty?
Yes. The ALF60915 is covered by Air Lift’s Limited Lifetime Warranty against manufacturing defects, with no mileage restriction. Air Lift also offers a 60-Day Ride Satisfaction Guarantee, which allows customers to return the product if they are not satisfied with the performance improvement. Review Air Lift’s warranty terms at airliftcompany.com for full details and claim procedures.
Can the ALF60915 be used on a coilover suspension?
No. The ALF60915 and all Air Lift 1000 universal kits are designed specifically for open coil spring suspensions, not coilovers. Coilover systems use a combined shock absorber and spring assembly where the spring wraps around the shock body. The Air Lift 1000 spring cannot be installed in a coilover assembly and is not appropriate for that application.
How does the ALF60915 affect my ride quality when unloaded?
When the ALF60915 is inflated to the minimum recommended 5 PSI with no load on the vehicle, most users report minimal change to normal ride quality compared to the factory coil spring alone. The air spring adds a slight supplemental spring rate at low pressure but does not stiffen the ride noticeably under light-load conditions. For best results, deflate the air springs close to minimum pressure during normal unloaded driving and reinflate when hauling or towing.
Installation Instructions
- Unload the vehicle and allow it to return to normal, unloaded ride height before beginning installation.
- Safely lift and support the vehicle. Access the coil springs from below the vehicle.
- Measure the coil spring inside diameter and inside height to confirm the ALF60915 is the correct kit before installing.
- If applicable, install heat shields around the air spring with the supplied clamps to protect the air spring from exhaust heat.
- Compress the air spring by hand and insert it into the inside of the coil spring.
- Position the air spring so it seats properly within the coil spring travel range without contacting the shock absorber shaft or upper spring seat.
- Route the air line from the spring through a protected path away from exhaust, steering, and moving components.
- Connect the air line to the tee fitting and route both lines to the Schrader valve mounting location.
- Mount the Schrader valves in an accessible location for inflation and deflation.
- Lower the vehicle and inflate the air springs to 5 PSI minimum before driving.
- Adjust pressure based on current load requirements, up to 35 PSI maximum.
