What's the advantage of using truxxx keys instead of adjusting the torsion bars?

That is BS ,the ride will be just as stiff and hard with keys and you will need to get an alignment with keys also . the Keys put the same stress on the T bars . anyone who thinks you don't need to get an alighment after cranking the T bars or installing keys is going to find out the hard way what new tires cost in a hurry . for an inch crank the T bars and get an aligenment ,for more get the Cognito leveling kit with the A arms .
