7\" lift with Echobit flips, Driveshaft? I want to use the Echobit bolt on shackle flip. They claim like 5 3/4" of lift, is this true? I already have about 1 1/2" of lift out back thanks to a set of 3/4 ton capacity 6 leaf springs the previous owner installed. Thinking this wil give me somewhere around 7"s of lift out back. Will I have to lengthen my driveshaft with this? I really don't want to but if I have to its not out of the question. Also will I need longer brake lines? If it were just 6" of lift like I want I wouldn't worry but this whole number 7 scares me a little. I am going to use Superlift 6" springs and probably a zero rate to even it out up front.
