just built my own 3" body lift on the sub/avy platforum. have done them before. order the performance acc blocks from 4 wheel parts. order the bolts off amazon ect. (170mm iirc).
everyone talks shit on them, but just like anything, if done by a hack in a trailer park.. it will be a hack. when used they offer many benefits, such as clearing larger tires with keeping the center of mass lower for better handling, easier access for maintence. opens up the possibility to do mods everyone else cant! ECT this is my 2003 zf6 built engine pull truck, just parking lot pose'n
