i had the torsion bar lift keys, and they suck!!!! all they do is push the lower control arm down to max, and you can't find shocks to fit right, i snapped 2 shocks right in half, THEY KILL BALL JOINTS TOO, and if you hit a big pot hole theres no down travel left in the suspension so the whole truck drops like a lead weight into the hole.
i know they are cheep and they are easy to install but, DON'T DO IT, YOU WON'T BE HAPPY.
i say put a body lift kit in, make sure you get the brackets to relocate the bumpers front and rear, and you could fab up some metal skirts to hide the space between the bed and frame.
body lift kit will still give the clearance for tires and leave the factory ride alone for about $150 with everything i just mentioned, and you can get a 2 inch or a 3 inch lift.
