Energy Upper Bumps ***UPDATE***
I have been using the 2 1/2" ones with a little improvement over stock, they work OK. They just mash down and give me little sooner overload engagement. http://www.summitracing.com/parts/ens-9-9109g/...

At the risk of being completely wrong , as I am by no means a suspension expert , this type of spacer seems to alter the spring dynamics in a negative way . In a spring pack the leaf above is in continuous contact with the one above over it's entire area . It seems that the lower overload leaf is meant to perform the same way , when the spring pack is loaded it will lay on the overload over it's whole length . With the Stable Loads , or similar ,it will have a point load on the spring pack above . I realize that leaf springs are not perfectly seated on each other but the principle is there .
