Grodyman, the solid block does not eliminate the flex in the spring pack. It simply reduces or eliminates the travel for the overload contact. Typically, it will make the vehicle suspension stiffer, and for some people could be a harsh ride.

Yep, simple physics here at work. It simply engages the lower overload spring sooner. This gives you the ability to carry more weight, with less sag on the spring pack. Now...one ton trucks are able to carry more weight with less sag due to having an upper overload that engages to prevent sag and keep a 3\4 ton pack to maintain the ride customer want that want a luxury truck and a heavy hauler.
My truck rides like a truck now with the stiff 19.5's. When I load my camper, engage the stableloads and level out my bags, it rides great! Do I kiss my caddy truck ride? Sometimes, got spoiled. But... my tuck is a truck and it works fine.
