AIR SPRING IDENTIFICATION

To assist with the correct air spring identification a visual inspection of the air spring is recommended. There are two air spring identification markings:

The air spring part number is provided on a decal on the upper bead-plate (refer to Item 1 in Figure 9)
Moulded into the air spring rubber bellows (refer to Item 2 in Figure 9).
