How to Identify an Air Spring

Step 1

air spring identificationThe original equipment or aftermarket number is affixed to the top plate of the air spring assembly. Then just double-check the product photo in the main body of the Goodyear Engineered Products catalog. If this number is unknown due to wear on the sticker or other reasons, refer to steps 2 through 6.

Step 2

Begin your search with the flexible members number, which is molded into the rubber part of the air spring.

Step 3

Step 4

Measure the width of the piston or bottom bead plate, making a note of the bolt pattern or taps. Be sure to note how the bolt pattern is oriented compared to the bolt on the top plate (incline or rotated).

Step 5

Compress the bag as far as possible with no air pressure and measure from the bead plate to the bottom of the piston. This is known as the compressed or minimum height. This will help determine if there is an internal bumper.

Step 6

Measure the distance from center to center of each bolt on the top and bottom of the air spring.
