  • FAQ

      • Q. Will adding air springs increase the Weight Rating of my vehicle?

        A. No. Adding air springs will not change the Weight Rating (GVWR, GCWR, GAWR) of your vehicle. Our air springs simply increase your suspension’s ability to support heavy loads. We strongly recommend that you never exceed your vehicle’s Weight Ratings. Exceeding your vehicle’s rating is dangerous and will void your Air Lift warranty.

      • Q. Do you have to add an On-Board Air Compressor System to your air springs?

        A. A compressor isn’t required, but it is convenient! An On Board Air System allows you to inflate and deflate your air springs on-the-go. Compressors remove the hassle of pulling over or searching for service stations with air pumps. With our onboard compressor system, all adjustments are automatic and made with the touch of a button- all while driving!

      • Q. How do I get replacement parts?

        A. You can get parts from your dealer, or directly from Air Lift Company. Contact Air Lift via email at service@airliftcompany.com or call (800) 248-0892.

      • Q. Do I always have to keep the air springs inflated? How much pressure do I need?

        A. Yes, you should always maintain the recommended minimum air pressure of 5 PSI, even if your vehicle isn’t loaded. This keeps the air springs “in shape” and able to perform without rubbing or wearing.

      • Q. How long do air springs last?

        A. Forever! If they are properly installed and maintained, our air springs can last indefinitely. Just check the pressure regularly, or use an on board air system to maintain it for you. Air Lift offers a Lifetime Warranty on all of our air spring kits.

      • Q. Can air springs raise or lower my vehicle?

        A. No. While adding air can cause your vehicle to ride an inch or two higher, air springs are not designed to raise your vehicle above factory height.

        If you DO want to lower your vehicle, visit Air Lift Performance line of products, which feature air spring systems designed to replace your existing suspension for lowered stance and higher performance.

      • Q. My vehicle rides rough. Will adding air springs improve my ride?

        A. Absolutely! Air springs are engineered to increase ride quality when carrying heavy loads and help fatigued springs ride smoothly. Our air springs greatly improve the ride of larger trucks.

      • Q. Can I use air springs with factory overload springs?

        A. Yes, most of Air Lift’s applications work with overload springs. Check our application guide for your vehicle.

      • Q. Will raising the vehicle on a hoist for service work damage the air springs?

        A. No. The vehicle can be lifted on a hoist for a short-term service work such as tire rotation or oil changes. However, if the vehicle will be on the hoist for a prolonged period of time, support the axle with jack stands in order to take the tension off the air springs.

      Air Bags with no Compressor System

      Horizontal cut in the side of the air bag. Bag leaks.Show Div

      Cause Action
      Air bag bottomed out. Rubber flex member was pinched between two ends of air bag. Insufficient pressure in air bags for load. Replace air bag and increase pressure. Work your way down to desired result. For motorhomes, start at 100 psi.
      Air bag bottomed out. Air bag is suspension limiter in compression. Add or adjust jounce bumper for full contact before air bag bottoms out, especially for 4WD vehicles.
      #1 cause of air bag mutilation is insufficient pressure for load or use. Consider adding a Load Controller for convenient air pressure adjustment.
      Insufficient pressure in air bags for amount of suspension travel.

      		 Must increase pressure when more suspension travel is needed.

      Other cut on air bag.Show Div

      Cause Action
      Road Debris Replace air bag.
      Insufficient clearance around air bag and is cut by object attached to vehicle. Move object out of the path of the air bag. Must have a minimum of ½” clearance around bag.

      Replace air bag.

      Rub mark on air bag. Bag leaks.Show Div

      Cause Action
      Road Debris Replace air bag.
      Insufficient clearance

      around air bag.

      		 Check for alignment and

      adjustment of air bag to

      frame or tire. Re-adjust

      away from frame or tire.

      Also check for clearance

      to brake cable,etc.
      Some kits call for a

      minimum clearance

      between frame and tire.

      Check installation manual.
      Call Tech Support at 1-800-248-0892.

      Air bag is melted.Show Div

      Cause Action
      Not shielded from exhaust system. Possible incorrect installation. Install heat shield kit. Replace air bag. Call Tech Support for heat shield kit.

      Air Spring will not inflate.Show Div

      Cause Action
      Air is leaking out too fast

      due to a massive leak.

      		 Make sure all air line

      connections are ok especially at air bag fitting.
        Inspect entire length of air

      line for damage or melted

      air lines. Replace as

      necessary.
      Check air bag for massive

      leak or hole.
      Call Tech Support at 1-800-248-0892 if the actions do not work.

      Air spring will not hold air (more than 2-3 psi/week).Show Div

      Cause Action
        Check to make sure

      schrader valve is tight

      Flex member is pulled away from the crimp.Show Div

      Cause Action
      Ends of air bag are not

      parallel causing uneven stress in extension. Poor installation.

      		 Adjust air bag. Replace air bag.
      Possible defective air bag. Call Tech Support at 800-248-0892.
      Over-extended air bag during rough driving. Add suspension limiting

      straps if necessary.

      System Leaks

      Leak in system.Show Div

      Cause Action
      Hose may be crimp,

      pinched, kinked, cut, or

      burst. Connections may

      not be secure, etc.

      		 If there is a small leak in

      the air system, it may be

      necessary to use a spray

      bottle with a water and

      soap solution to find it.

      Leak at the air line fitting.Show Div

      Cause Action
      Air line fitting not tight enough. Tighten air fitting ¼ to ½

      more turns.
      A piece of air line which has not been cut off square at the end. Remove air pressure from system and re-cut air line tube and ensure it has a square end.
      Air line is not completely pushed in. Push air line into the air fitting so it

      is secure.
      Loose valve core in air fitting. Tighten valve core

      Attachments

      Brackets are bent or broken, and or bracket to frame bolts are broken.Show Div

      Cause Action
      Air bag bottomed out from low pressure. Increase pressure, replace

      or repair brackets and/or

      bolts. Use Grade 8 bolts

      only.
      Air bag bottomed out from maximum suspension travel in compression. Remove air pressure from system and re-cut air line tube and ensure it has a square end.
      Air bag bottomed out due to incorrect installation.

      Brackets are too close.

      		 Review installation manual or call Tech Support for correct mounting height. Adjust installation as necessary.

      Lower bracket has moved away from the axle towards the end of the leaf spring.Show Div

      Cause Action
      Suspension over-travel

      which causes “hook” of

      lower bracket to bend up

      and detaches it from axle

      U-bolt or spring retainer.

      Over-travel could be the

      result of incorrect

      installation. See section on

      four wheel driving.

      		 Review installation manual

      or call Tech Support for

      correct mounting height.

      Adjust installation as

      necessary. Add

      suspension limiting straps

      if necessary to limit travel

      in extension. R&R lower

      bracket as necessary.
