The Blazer I just bought has some shock issues. It's currently got Heckethorn (believe that's right) shocks on it, and rides like it's got marshmallows on all the corners. I want to upgrade the shocks to either Rancho or Bilstien shocks, but I'm not 100% sure on how to determine what shocks I need, since the truck has roughly an 8" lift on it. Summit Racing splits their shocks up into 5-6" and 9-12", and I thought it would be better to go with a higher lift, rather than a shorter one (so I don't beat the shocks up if I extend it all the way). However, the only thing they show in the 9-12" category are Skyjacker shocks. Not sure how those compare to the Bilstien and Rancho stuff. Also, I want to upgrade the steering stabilizer, but I'm not sure if I should go with a single or a dual. Summit's website says single up to 35", which is what the K5 currently has on it, but I'll be going with 39s as soon as I get my body lift on. Only question I have about a dual setup, like the Rancho RS5000 setup, is if it'll simply bolt up in place of the stock single stabilizer shock, or if any work needs to be done to it to get it to fit.
