Lifted truck question
 

I bought a 2001 chevy Silverado 1500 recently and the truck rides pretty bad. It has a 6" block in the back and the torsion keys are maxed out I believe. All the shocks are blown out so I plan I replacing them but my question is could I buy longer shocks in the front so the shocks wouldn't be maxed out from the torsion keys being raised or could I buy a leveling kit that comes with 2" keys then buy new shocks that are 2 inches longer. Let my know what you guys think

I know the torsion keys being maxed out will make it ride more rough. Im not sure the exact fix but basically you will need more lift to lower the keys, and should help ride comfort.
