The company even assembles G-Machine Packages with improved items in four levels of intensity. We went for the Level II, using polygraphite bushings, powdercoated front and rear sway bars, and KYB shocks in addition to the replacement ball-joints, tie-rods, and idler arm. We upgraded another notch to Edelbrock shocks.
