[John S Peterson]

The shock "ratio" is what determines how they react to "jounce and rebound" Typically you find ratios of 50/50 on most passenger vehicles, meaning they react equally in each direction. Aftermarket shocks ie Koni, Alden and so on can be purchased with an adjustment that allows you to taylor the ratio slightly to get it to preform to your needs. On the drag racing shock, they are usually a 90/10 shock which allows them extend very quickly to get the front end up and transfer the weight to the rear, and slower compressing.
