Keys refer to reindexing keys. The torsion bars that come on some Dakotas and Durangos have a hex head on it's end which the keys capture. The reindex keys have that hex hole slightly turned. This makes the torsion bars twist a little more and that raises the truck. However, in my opinion they are a waste of money because you can crank the bars as much as the reindex keys can lift, and besides you can only lift the front end by only 1.5 to 2 inches before you run into trouble with the front end geometry
