If the rear suspension on your vehicle is sagging on either one or both sides then there is an issue with the airbag suspension system.

One solution is to replace a suspension airbag which sometimes resolves the issue but many owners even after replacing both the rear airbags discover that the problem still exists. This is due to the many components within the air suspension system that can fail, this includes airbags, air compressor, ride height sensors, air valve block, air lines or air line connectors.

To correctly diagnose the cause of the issue can be a very lengthy and very expensive exercise.

The best solution to resolve all issues (permanently) is to convert your vehicles rear suspension to coil springs using one of our Airbag to Coil Spring Conversion Kits.
