Need ideas (and/or URLs to old posts discussing this) of what kind of mods: driveshafts,steering, etc, to make 4" or even 6" spring lifts work on our Blazers. I have 3 leaves up front, and 4 in the rear right now, front right pack has a cracked one. Will be getting new lift springs as soon as I can.. I need to collect info, and decide how much trouble I want to go through, and go with as much lift as I can. Thanks for anything., So far have removed fuel tank to have flushed, has a hole, and straps are rotted, and sending unit, and all lines and hoese are junk. All 12 body mount bolts are removed as of yesterday, waiting for new bushings, gonna lift body 1" higher with big washers. Axles are cleaned and refilled. Front driveshaft is ready to install, if its correct length. <A target="_blank" HREF=http://content.communities.msn.com/isapi/fetch.dll?action=view_photo&ID_Community=RandyR72K5&ID_Topic=1&ID_Message=174>http://content.communities.msn.com/isapi/fetch.dll?action=view_photo&ID_Community=RandyR72K5&ID_Topic=1&ID_Message=174</A> '72 K-5 4x4, CST, 3.07, 4 speed, NP 205, 31' x 10.5", Olive green and primer, rusted out, rice smasher!
