I'm looking to lift my 81 K5 blazer pretty soon, I've already order the shackle flip kit from diy4x for the rear. But I have not yet decided what im going to do for the front. I was considering the 52" springs in the front until I heard about the on road driveability problems due to not having enough castor. I'm trying to spend the least amount of money possible being a college student, but still want to have some nice flex and be able to have a good time in it on the weekends but not effect the drivability it being my daily driver. So now I'm looking to build up my own springs. Have any of you built yourself a bastard pack? What kind of springoff of what vehicles would you start looking at to use?
