Competitive products have simply mirrored the shape of the original key, and indexed or changed the position of the hex to put more initial preload on the torsion bar. We went through the painstaking process of redesigning the entire adjustment system, as well as the shape of the key itself. And, we are the only aftermarket torsion key manufacturer that includes a complete forged replacement drive system and bolts with every kit we sell. The result? A patented, forged system that not only allows front lift options up to 3.0 in. (varying by make and model), but all changes down to near OEM at the bottom of the adjustment. Duck Head torsion keys have the widest adjustment range of any key on the market, meaning that you have control over which adjustment option is right for you. We even include special shock extenders when a particular truck requires it so that the vehicle rides just like it did from the factory guaranteed.GM TORSION KEY KIT
