I've got an 08 2.4 2LT with almost 50k on it. I looked around and found a set of AC Delco shocks that seem to be stiffer than the "normal" OTC replacement.The AC part number is 560-547. The dealers usually don't stock them, but I found them at Partstrain.com,[URL="http://http://www.partstrain.com/?source=adwords&s_kwcid={ifcontent:ContentNetwork} {ifsearch:{keyword}}|{creative}"][COLOR="Red" ,Thes shocks also work very nicely on a stock 08 Cobalt LS. The ride on both is firm, but not at all harsh.
