At first, you might think there wasn't a big difference between the ShockWaves and air shocks from this comparison (even the new compressor is "smaller"!). Well, there is a big difference, especially considering the Air Ride compressor is rated at .50-cfm @ 150-psi, and when you factor in a 2-gal. air reservoir tank, that's more volume than the old air shocks could ever imagine handling!
