if you think about it,you are doing the same thing with the ready lift that you are already doing,the only difference is is that you have less of the bolt going in to raise the key

 

The only thing you benifit from a ready lift is the shock extensions. The stock torsion keys will give you the same amount of lift as the Readylift or theTrux kit.Your better off getting longer front shocks!

Cranking the torsion bars just gives you clearance for larger tires. Yourreducing the sag of your suspension travel so it's causing problems.
