Types of Shocks, Pros and Cons

I have a car with Gabriel hi jacker rear air shocks in it right now and am thinking of changing over to hydraulic shocks to get a smoother ride.  Do air shocks give a rougher ride than hydraulic (when inflated).   Anyone know the differences in ride comfort between air and hydraulic?  

Hello,

First why do you have air shocks on the rear? Air shocks are intended for the rear of a vehicle to keep the vehicle at normal ride height when carrying a light load or towing. Sometimes they are installed on a vehicle when more clearance is needed due to over sized tires and wheels. This is not their real intent.
If you do carry light loads or tow and are not carrying a load or towing a 50psi minimum air pressure is needed not to damage the air bags. This will effect the ride quality of the vehicle due to the added spring rate.
Air shocks do have hydraulic damping just like a regular shock. Air shocks are just a regular shock with an air bag attached around it.
Straight hydraulic shocks will not raise the vehicle.
So if you don't need air shocks for load carrying or added clearance a hydraulic shock will give you the best ride quality for your vehicle.

Hope this helps.  

Thanks, it helps a lot.  The original owner of the car had the air shocks installed.  Upon removal, I found that one side was not holding air.  The travel distance of the shock was about 1 inch before they bottomed out.  Having leaf springs, it made for a ride like a haytruck.  I went ahead and installed hydraulics with much more travel. Now I know why the previous owner had that air - the tires rub on tight turns.  I've since installed a lower profile tire and now I have clearance.  The previous owner just took a cheap way out I guess.  Thanks for all the input.
