Thanks for the input, I allready have a lift for the rear, but wasn't sure about the front I was just gonna crank up the torsion bars, but after reading through all the FAQ. I ordered the new uca's from CALMINI. Still not sure if I want do do the body lift, guess I'll wait and see.
You can get two inches from a t-bar crank given that they are not already adjusted to raise the front at all. T-bar crank in the front and 2" blocks in the rear and you should be level. You will need a front-end alignment to correct your camber after the t-bar crank and longer shocks for the rear. With this you are like to need some trimming to your front bumper valance and maybe fender flares which will rub with your 33s.
UCA means for Upper Control Arm. If you wish to lift anything over 2" they are required to accomplish proper balljoint angles and more suspension droop travel. For a T-bar crank of 1-2" you do not need to replace your UCAs and longer front shocks are not needed when retaining stock UCAs.
It is definitely possibly but there are much easier ways to lift these 2wd trucks. Going from spring under to spring over is going to require some fabrication of new spring perches. I would recommend shackles or an ad a leaf kit and new shocks which is what most people do.
