Does the GX have the AHC system? The LX470 does, and it is a game changer on rough roads.
No. They have rear air ride and coil overs in the front. I swapped out the airbags in the wife’s to coils this summer. MetalTech, and others, make a kit. Airbags and the overall system generally don’t last and are expensive to replace. If you’re going to lift it anyway you’ll delete the airbags when you install a lift.
