Air Suspension Compressor Installation

Tighten all nuts and bolts to manufacturer’s specifications during the installation process.

Do not remove the air fitting from the air suspension compressor. Doing so may cause damage or void warranty. Remove the white shipping pin from the new air fitting and insert the air line until fully secure.

1 Installation is in reverse order of air compressor removal.

WARNING

Cracked air springs must be changed to validate the warranty on the compressor

Please read additional warranty information on the back of your invoice

Proper procedure for assessing your air spring’s condition

1 Turn off air suspension switch if equipped.

2 Refer to owner’s manual for proper lifting techniques and jacking points.

3 Raise the vehicle.

4 Inspect air springs for any type of cracks or excessive wear. Cracks in air springs are evident if they are leaking. This will cause the compressor to overheat from continuous operation.
