Questions about this item

How do I install the Unity rear air spring kit on my 2003-2009 Lexus GX470 and which step is commonly missed?

Remove the old air springs, fit the two new bags, then reconnect the air lines and electrical connectors; the step often missed is torquing the mounting bolts to the vehicle specification after the vehicle sits at ride height.

What maintenance or replacement will the Unity air spring kit need later?

Inspect the two air spring bags annually for cracks or abrasion and replace them if leaks develop; the compressor and air lines should also be checked during routine service.

What is the first limit that appears under sustained heavy loading with this Unity kit?

The air springs will reach their maximum pressure and stop lifting, causing the rear to sag until the load is reduced or the compressor cycles to maintain pressure.
