The Air Lift 1000 is an air spring suspension support system that installs inside the rear coil springs of compatible vehicles. It provides adjustable load support by allowing you to add air pressure to level the vehicle and improve ride quality when carrying cargo or passengers. The system consists of two air springs, air lines, inflation valves, and mounting hardware.
The Air Lift 1000 fits specific General Motors, Ford, Lincoln, Mercury, Nissan, Isuzu, Kia, and Toyota models. Fitment is divided into three installation sections: Section A covers GM A and X-body front-wheel-drive cars, Ford/Lincoln/Mercury full-size and mid-size cars, Chevy Lumina APV, Olds Silhouette, Pontiac Transport, Nissan Pathfinder, and Isuzu Trooper/Amigo/Vehicross. Section B covers Camaro, Firebird, Monza, Skyhawk, Starfire, Astre, Sunbird, and Vega. Section C covers GM E and H-body cars, Kia Sedona Van, Nissan Murano, and Toyota Scion XB. Consult the manual's vehicle listing to confirm your specific model and installation section.
No. Installing air springs will not change the GAWR (Gross Axle Weight Rating), GCWR (Gross Combined Weight Rating), or GVWR (Gross Vehicle Weight Rating) of your vehicle. You must not exceed your vehicle's GVWR as stated on the Safety Compliance Certification Label. Exceeding the GVWR is dangerous and voids the Air Lift warranty.
You will need: two hoists or floor jacks, safety stands, safety glasses, an air compressor or compressed air source, and a spray bottle with a dish soap and water solution (1 part dish soap to 4 parts water). For Section B installations on 1975 and later Vega, Monza, Starfire, Skyhawk, and Sunbird models, you will also need a drill with a 1/2" bit. For Section C installations, you will need a drill with a 3/4" bit. Pliers are needed to compress air line clamps during air line installation.
The kit includes: two air springs, two protectors (part 09447), one 15-foot hose (part 20315), six air line clamps (part 10638), six zip ties (part 10466), two valve caps (part 21230), four 5/16" hex nuts (part 21233), two rubber washers (part 21234), two 5/16" star washers (part 18411), two 5/16" flat washers (part 18405), one barbed tee (part 21236), and two valves (part 21455).
For Section A installations, you do not need to remove the coil springs. For Section B installations, you must remove the coil springs. For Section C installations, you do not need to remove the coil springs. The procedure depends on your vehicle's section. Consult the appropriate section in the manual for your specific vehicle.
The manual does not specify battery disconnection as a requirement for Air Lift 1000 installation.
Yes. Some Ford, Lincoln, and Mercury models come equipped with a rubber sleeve inside the rear coil springs. This sleeve must be removed before proceeding with installation. It can either be cut out or pulled out with vise grips.
The orientation depends on your vehicle's installation section. For Section A installations, insert the air spring with the stem end first and the valve stem pointing up. For Section B installations, insert the air spring with the stem pointing down. For Section C installations, insert the air spring with the stem pointing down. Always consult your specific section in the manual.
First, remove the plastic cap from the barbed stem and exhaust all air from the air spring by rolling it up towards the barbed stem. Replace the cap so the air spring holds its flat shape. Form the air spring into a hot dog bun shape. Then insert the stem end into the coil spring opening and push it in by hand or with a blunt object such as a spoon-type tire iron. Once fully inside, remove the cap and allow the air spring to assume its original shape.
The protector (part 09447) is a protective component that prevents the air spring from rubbing against the coil spring. For Section A installations, push the air spring to the bottom of the coil and insert the protector on top of the air spring. For Section B installations, push the air spring to the top of the coil spring and insert the protector on top of the lower spring seat. For Section C installations, push the air spring to the top of the coil and insert the protector on the bottom of the air spring, on top of the spring seat.
Tee air line installation is recommended for most applications. Use a single tee that connects both air springs together. Dual air lines are used only when weight in the vehicle varies significantly from one side to the other and unequal pressures are needed to level the load. With dual lines, each air spring has its own separate inflation valve, allowing independent pressure adjustment.
The air line must be maintained at least 8 inches from the exhaust system to prevent the line from melting. Additionally, ensure there is at least 2 to 3 inches of clearance between the tail pipe and the air spring.
Use this procedure for all air line connections: (1) Slide an air line clamp onto the air line. (2) Push the air line over the barbed stem, covering all the barbs. (3) Using pliers, compress the ears on the air line clamp and slide it forward until it fully covers the barbed section. Ensure the clamp completely covers all barbs to prevent leaks.
Select a location for the inflation valve that is protected and accessible with an air hose. Options include the gas cap well, trunk, rear bumper, fender flange, or behind the license plate. For tee systems, use a single inflation valve. For dual systems, mount separate valves in the rocker panel flange or rear bumper.
Drilling is required for some vehicles and optional for others, depending on your installation section. For Section A installations, no drilling is required. For Section B installations on 1975 and later Vega, Monza, Starfire, Skyhawk, and Sunbird models, you must drill a 1/2" hole in the lower spring seat using the template provided. For Section C installations, some vehicles do not have a hole in the lower spring seat and require drilling a 3/4" hole using the template. Always use the template provided in the manual and center punch before drilling.
Drill a 5/16" hole for the inflation valve mounting location. This hole is used for both tee and dual air line systems.
For Section A installations, shock absorber removal is optional. The manual states that if additional clearance between the coil is needed, you can remove the shock absorbers from the lower mountings and lower the suspension an additional two inches. For Section B installations, you must detach the shock absorber lower ends from the axle to permit removal of the coil spring. For Section C installations, shock absorber removal is not mentioned as required. If shock absorbers are removed, they should be reattached after the air springs are installed.
The inflation valve (part 21455) is a fitting that allows you to add or remove air from the air spring system. It is mounted on the vehicle body (such as the bumper, fender, or gas cap well) and connects to the air line system via a 5/16" hole. You attach an air hose to the valve to inflate or deflate the air springs. The valve includes a rubber washer (part 21234) that serves as an outside weather seal.
The maximum air pressure is 35 PSI. Never inflate the air springs beyond 35 PSI. Although the air springs are rated at a maximum inflation pressure of 35 PSI, the actual air pressure needed depends on your load and GVWR. Always maintain normal ride height and do not exceed your vehicle's GVWR.
The minimum air pressure is 5 PSI. The air springs can safely be run at zero air pressure, but maintaining a minimum of 5 PSI is recommended. When raising the vehicle on a hoist for service work, maintain at least 5 PSI to reduce tension on the suspension and brake components.
No. The air springs can safely be run at zero air pressure. However, it is recommended to maintain a minimum of 5 PSI. For normal operation, adjust the air pressure to maintain ride height at all times, regardless of load.
Yes, the vehicle can be lifted on a hoist for short-term service work such as tire rotation or oil changes without damaging the air springs. However, if the vehicle will be on the hoist for a prolonged period of time, support the axle with jack stands to take the tension off the air springs. Use of on-board leveling systems do not require deflation or disconnection.
Before operating the vehicle, complete the post-installation checklist: (1) Clearance test — Inflate air springs to 30 PSI and ensure at least 1/2" clearance around each bellow away from tires, brake drums, frame, shock absorbers, and brake cables. (2) Leak test — Inflate to 30 PSI and check all connections with soapy water solution. (3) Heat test — Ensure at least 6" clearance from heat sources; install heat shield if included. (4) Fastener test — Recheck all bolts for proper torque and re-torque after 100 miles. (5) Road test — Drive 10 miles and recheck for clearance, loose fasteners, and air leaks.
Inflate the air springs to 35 PSI. Spray all connections and inflation valves with a solution of 1 part liquid dish soap and 4 parts water. Spot leaks by looking for bubbles in the soapy water. After testing, deflate the springs to the minimum pressure required to restore normal ride height, but not lower than 5 PSI. Check air pressure again after 24 hours. A 2 to 4 PSI loss after initial installation is normal. If the loss is more than 5 PSI, retest for leaks.
If there is a problem with the inflation valve, check the valve core by tightening it with a valve core tool. If the leak is in the air line, remove the air line from the barbed fitting. Cut the air line off a few inches in front of the fitting and use pliers or vise grips to pull or twist the air line off the fitting. Do not cut off the air line completely as this will usually nick the barb and render the fitting useless. If these steps do not resolve the problem, call Air Lift customer service at (800) 248-0892.
Check the air pressure weekly. Always maintain normal ride height by adjusting air pressure as needed. Never inflate beyond 35 PSI.
If the air springs are properly installed and maintained, they can last indefinitely. Proper maintenance includes checking air pressure weekly, maintaining normal ride height, avoiding bottoming out or over-extension, preventing rubbing against other components, and following all installation and operation instructions.
After 30 days or 500 miles, whichever comes first, recheck the air spring system. Inspect all parts for signs of rubbing or abrasion and identify and move the source if possible. If relocation is not possible, the air spring may need to be remounted. If professionally installed, consult the installer. Check all fasteners for tightness.
When increasing load, always adjust the air pressure to maintain normal ride height. Increase or decrease pressure from the system as necessary to attain normal ride height for optimal ride and handling. Remember that loads carried behind the axle (including tongue loads) require more leveling force (pressure) than those carried directly over the axle. When carrying a payload, it is helpful to increase tire inflation pressure by 2 PSI above normal for each 100 lbs of additional load on the axle.
No. Air pressure can be adjusted with any type of compressor as long as it can produce sufficient pressure to service the springs. Even a bicycle tire pump can be used, though it requires significant effort. However, an on-board air compressor system allows you to inflate and deflate your air springs with the touch of a button from inside or outside the vehicle. Air Lift offers single or dual path systems with wireless or analog control options.
First, leak test the air line connections by spraying them with a soapy water solution and looking for bubbles. Inspect the air lines to ensure none are pinched (tie straps may be too tight — loosen or replace them). Inspect the air line for holes and cracks and replace as needed. Look for kinks or folds in the air line and reroute as needed. If the leak is at the inflation valve, check the valve core by tightening it with a valve core tool. If these steps do not solve the problem, it may be caused by a failed air spring (factory defect or operating problem). Call Air Lift at (800) 248-0892 for assistance.
If the vehicle's headlights are shining into the trees or the vehicle is leaning to one side, it is not level. Raise the air pressure to correct either of these problems and level the vehicle. You may need to maintain different pressures on each side of the vehicle if loads such as water, fuel, or appliances cause the vehicle to be heavier on one side. As much as a 50 PSI difference between sides is not uncommon.
If the vehicle has a rough or harsh ride, it may be due to either too much pressure or not enough. Try different pressures to determine the best ride comfort. Adjust the pressure up and down to find the best ride. If the vehicle rocks and rolls, adjust the air pressure to reduce movement. Stability issues such as roll control, bounce, dive during braking, and sponginess usually require an increase in pressure.
If the front of the vehicle dives while braking, increase the pressure in the front air bags if equipped. This is a stability issue that usually requires an increase in pressure.
If it is suspected that the air springs have bottomed out, increase the pressure. Bottoming out occurs when the air spring compresses completely and loses its support function. Increasing pressure will prevent this condition.
For Section A, no. For Section B, yes. For Section C, no. Your vehicle's section determines whether coil spring removal is required.
For Section A, no. For Section B (1975+ Vega, Monza, Starfire, Skyhawk, Sunbird), yes — drill a 1/2" hole. For Section C, some vehicles require drilling a 3/4" hole. Use the template provided.
35 PSI. Never exceed this pressure. The actual pressure needed depends on your load and GVWR.
5 PSI is recommended. The air springs can safely run at zero pressure, but maintain 5 PSI when raising the vehicle on a hoist.
At least 8 inches from the exhaust system to prevent melting. Maintain 2 to 3 inches clearance between the tail pipe and air spring.
Clearance test at 30 PSI (1/2" minimum around bellows), leak test with soapy water, heat test (6" minimum from heat sources), fastener test, and 10-mile road test.
Weekly. Always maintain normal ride height and never exceed 35 PSI.
Recheck the air spring system for signs of rubbing or abrasion, check all fasteners for tightness, and verify clearances.
A 2 to 4 PSI loss after initial installation is normal. If loss exceeds 5 PSI, leak test the air line connections and inflation valves with a soapy water solution (1 part dish soap, 4 parts water) and look for bubbles. Check the valve core by tightening it with a valve core tool. Inspect air lines for pinches (loosen tie straps if needed), holes, cracks, kinks, or folds. If the leak persists, call Air Lift customer service at (800) 248-0892.
If headlights shine into the trees or the vehicle leans to one side, raise the air pressure to level it. You may need different pressures on each side if loads are uneven. As much as a 50 PSI difference between sides is normal for uneven loads.
Try different pressures to find the best ride comfort. Rough ride can result from too much or too little pressure. If the vehicle rocks and rolls, increase pressure to reduce movement. Stability issues (roll, bounce, brake dive, sponginess) usually require increased pressure.
Ensure the air line is at least 8 inches from the exhaust system. Check that the tail pipe is at least 2 to 3 inches from the air spring. Loosen clamps and rotate or move the line to obtain additional clearance. If a heat shield was included, install it. If rubbing is detected during the 30-day/500-mile check, identify the source and move it if possible. If relocation is not possible, the air spring may need to be remounted.
If the front dives during braking, increase the pressure in the front air bags if equipped. This is a stability issue that requires increased pressure.
Increase the air pressure. Bottoming out occurs when the air spring compresses completely and loses support. Higher pressure prevents this condition. If bottoming out continues, verify that the air springs are properly installed and that the vehicle is not exceeding its GVWR.
