Questions about this item

How long does the rear air spring typically last under daily driving before it needs replacement?

Unity designs its Elite Suspension Line air springs for long-lasting reliability, backed by over 50 years of aftermarket manufacturing experience.

Does the air spring run hot or make compressor noise when the vehicle is loaded for a full day?

The air spring itself has no moving parts; heat and noise come from the compressor, which only runs to maintain pressure as needed.

Which O-ring seal kit is included and does it fit the 2005 GMC Envoy XUV without extra parts?

The product includes an O-ring seal kit and fits the 2005 GMC Envoy XUV directly, with no additional components required.
