Review on Suspension Leveling 1988 2006 Silverado Sierra by Tim Clark

As you can see from the photos, the keys do not look at all like the photos on the web. There should be two indentations at the bottom. One is for the adjustment screw and the other is needed for the torsion wedge remover. Also, the sides of the hex keyhole must be flat to hold the torsion bar securely in place. The raised ridges in these keys wear out fairly quickly, weakening the torsion bar. This will be very noisy and will eventually round off the hole, rendering it unusable. I'm about to get her back.
