ProRyde - Duck Head Torsion Key Leveling Kits

The result? A torsion bar key that not only makes front ride height changes up to 3.0" beyond what the OE key offers, but all changes in between. Duck Head torsion bar keys have the widest adjustment range* of any key on the market, and without ever needing to remove it or "re-calibrate" it as some other manufacturer's keys require. ProRYDE has also made the effort to include special shock extenders whenever a particular truck requires it so that the vehicle rides just like it did from the factory.
