5. The hydraulic suspension system for lowering the ride height of a vehicle of claim 4 wherein said inlet being positioned approximate to the bottom of said rebound chamber, whereby when fluid being moved from said central manifold to said rebound chamber said floating bearing being raised in said rebound chamber, thereby shortening the length of said hydraulic shock.

6. The hydraulic suspension system for lowering the ride height of a vehicle of claim 1 wherein, when said floating bearing being moved and said hydraulic shock being shortened, fluid may be removed from said hydraulic shock through said inlet and back into said central manifold thereby lengthening said hydraulic shock.

7. The hydraulic suspension system for lowering the ride height of a vehicle of claim 1 further comprising a fluid reservoir for each of said hydraulic shocks, each of said fluid reservoirs adapted to take up hydraulic fluid from said hydraulic shocks when the ride height of said vehicle being lowered.

8. The hydraulic suspension system for lowering the ride height of a vehicle of claim 1 wherein said central manifold comprising:

a fluid accumulator;

a pump including a power supply; and

a hydraulic connection and fluid line for each hydraulic shock;

wherein, said pump being adapted to pump fluid from said fluid accumulator through each of said hydraulic connections and fluid lines for lowering the ride height of the vehicle.

9. The hydraulic suspension system for lowering the ride height of a vehicle of claim 8 wherein said central manifold having thermal expansion means being adapted to adjust for thermal expansion of said fluid.

10. The hydraulic suspension system for lowering the ride height of a vehicle of claim 1 wherein said vehicle being an automobile with four wheels, where said system including four hydraulic shocks attached to each wheel.

11. A hydraulic shock for a suspension system for lowering the ride height of a vehicle comprising:

a floating bearing being positioned in the rebound chamber of said hydraulic shock and being mounted on a piston rod in said hydraulic shock, where said floating bearing being able to move longitudinally along said piston rod; and

an inlet being positioned approximate to the bottom of said rebound chamber and being adapted to move fluid into said hydraulic shock for moving said floating bearing;

wherein, when fluid being moved through said inlet into said rebound chamber, said floating bearing being raised in said rebound chamber thereby shortening the length of said hydraulic shock.

12. The hydraulic shock for a suspension system for lowering the ride height of a vehicle of claim 11 where said floating bearing having a first fluid tight seal between an outside wall of said floating bearing and an inside wall of said rebound chamber and having a second fluid tight seal between an inside wall of said floating bearing and an outside wall of said piston rod.

13. The hydraulic shock for a suspension system for lowering the ride height of a vehicle of claim 11 wherein said floating bearing having a donut shaped cross-section.

14. The hydraulic shock for a suspension system for lowering the ride height of a vehicle of claim 11 wherein when said floating bearing being moved and said hydraulic shock being shortened, fluid may be removed from said hydraulic shock through said inlet thereby lengthening said hydraulic shock.

15. A method for lowering the ride height of a vehicle comprising the steps of:

providing at least one hydraulic shock, where each of said hydraulic shocks including:

a floating bearing being positioned in the rebound chamber of said hydraulic shock and being mounted on a piston rod in said hydraulic shock, where said floating bearing being able to move longitudinally along said piston rod; and

an inlet being positioned approximate to the bottom of said rebound chamber and being adapted to move fluid into said hydraulic shock for moving said floating bearing;

wherein, when fluid being moved through said inlet into said rebound chamber, said floating bearing being raised in said rebound chamber thereby shortening the length of said hydraulic shock;

mounting each of said hydraulic shocks to the suspension of the vehicle;

connecting a central manifold to the inlet of each of said hydraulic shocks;

lowering the ride height of the vehicle by moving fluid from said central manifold into each of said hydraulic shocks thereby moving said floating bearing in each of the hydraulic shocks.
