Find My Parts

If you KNOW the Original Equipment or Aftermarket part number enter it in the yellow search bar below.

If you DON’T KNOW the Original Equipment or Aftermarket part number click here for instructions on how to find your part.

(NOTE: The Original Equipment or Aftermarket part number is typically affixed to the top plate of the air spring assembly.)

FOLLOW THE STEPS BELOW IF YOU DON’T KNOW YOUR PART NUMBER

  • Use the steps below to identify key attributes of the air spring you are looking for and make notes for later reference.

1 Search for the TYPE OF AIR SPRING.

2 Search the AIR SPRING NUMBER. The number is molded into the rubber part of the air spring.

3 Determine the material of the BOTTOM PLATE / PISTON TYPE.

4 Measure the TOP PLATE DIAMETER, making a note of the bolt pattern or taps (TOP PLATE HOLE / STUD QTY).

5 Measure the BOTTOM PLATE DIAMETER (or bottom bead plate), making a note of how the bolt pattern is oriented compared to the bolt of the top plate (BOTTOM PLATE ALIGNMENT) and, if applicable, making a note of the bolt pattern or taps (BOTTOM PLATE HOLE / STUD QTY).

6 Measure the height of the air spring (with no air pressure) from the top plate to the bottom piston. This is MAX HEIGHT. Compress the bag as far as possible with no air pressure and measure the height. This is the MIN HEIGHT.

7 Measure center to center of TOP bolts (TOP PLATE C TO C DIAMETER), and center to center of BOTTOM bolts (BOTTOM PLATE C TO C DIAMETER).

Additional information, if applicable, does it have a BUMPER and a BRACKET?

  • Then: using the yellow search bar type in “the Type of Air Spring” or “Air Spring Number”, then select the appropriate results for Steps 3-7 using the sort function.
