Ride can only be better than factory. To me RR feels too soft, and sways around like a boat would, especially when turning a corner at moderate speed. RR is a very heavy vehicle, and inflated airbags just cant hold side-to-side movement as well as traditional springs. Each of the above kits comes with instructions on how to disable the entire EAS system, error messages included. I have not switched yet, but maybe bsolidgold can tell us whats involved in disabling it.
