    *Air Suspension Structure:

     

    1. Stud
    A permanent part of the bead plate assembly used to attach the airspring to the suspension.

     

    2. Combo Stud
    Combination mounting stud and air fitting.

     

    3. Blind Nut
    A permanent part of the bead plate assembly providing an alternate mounting system to the stud.

     

    4. Air Fitting Hole
    A tapped hole usually 1/4" N.P.T. providing air entrance for the part.

     

    5. Bead Plate
    Permanently crimped onto the bellows at the factory allowing complete part leak testing prior to shipment.

     

    6. Bellows

    The heart of an Airide spring. Includes at least four plies, or layers, of material–an inner layer, two plies of cord-reinforced fabric, and an outer layer.

     

    7. Bumper (Optional)
    A solid molded rubber fail-safe device used on many suspension applications. Prevents excessive damage to vehicle and suspension in the case of sudden air pressure loss.

     

    8. Piston
