has anyone heard of the Ready Lift leveling kit for 97-03 f150? It has torsion keys, i know they tighten up the torsion bar, they report 2.5" of front lift. Is this a good system.

 

Nope havent heard of it. Sorry.

 

Personally, I wouldn't use them. They just allow you to put more preload on your torsion bars than you can with the OEM adjustment keys. THis will cause premature wear on your steering and suspension components and destroy your ride quality. I'd just crank up the torsion bars with the OEM adjustment keys. If you want more lift inexpensively I'd suggest a body lift.
