I feel that when you put shock absorbers on a car . Isn't that the same as mercury recoil reducer? The Edwards worked with a spring and a sliding weight . Mercury is more like a shock. Now I know I can replace my shocks with a straight bar only heaver and I won't feel the bumps . Larry
Shocks support the whole car, that is the theory of the recoil reducers added on the end of the stock. Spring or hydraulic. one inside does about the same as carrying around 4 new shocks in your trunk...... Jim
