First off, I want to make my '94 Blazer sit just a tad bit higher and I want to crank the torsion bars. What all do I need to do to get this accomplished. I know I might need to throw some 2" blocks in the rear. I want it to sit higher without really lifting it and sit level. Sitting level is the important part here. It's just a 4x4 not a Z71. Thanks!
