I put the sulastic shackles on this weekend. They helped a lot with the big jolts from potholes and bridge joints. It's still stiffer than it needs to be for a 1/2 ton 2wd truck but I can tolerate it. I found a thread on this subject on another site and someone had researched and found that the struts on Tahoes and Suburbans are identical to the trucks except the coil springs are softer. Unfortunately if any of them tried to swap them onto a truck they didn't report it in their posts. I might check into that some day but for now I'm through throwing money and labor into it. Just for the record, the sulastic shackles are a pain in the butt to install. Hopefully they'll last as long as I own the truck. Thanks for all the replies.
