i have no personal experience with keys but seems that using these will not effect torsion bar pre-load. cranking the bars will however make the ride stiffer. both will raise ride height and make suspension components ware faster.
if it was me i would crank the bars and get a set of mono-tube shocks, like monroe reflex or KYB's
Thats what I did, I cranked up the Tbars 4 complete turns and got some good monotube shocks (KYB MonoMax's). Yeah, it rides different, I cant say thats its a good thing or a bad thing. It is stiffer, but I did that months ago and I done got used to the way it rides. Keep in mind, these are trucks, not lincoln navigators.
