also will i have to get a front end alignment after the "lift"??

 

how do i go about doing such lift??

Depends upon if the dealer or previous owner already has them cranked up. If you do give them a couple turns or swap the keys out, yes you should always get a re-alignment.

the whole truck is completly slock...so if i do turn them up i only need about 2-3 inches...think the stock keys will get that much done???

You should be able to crank the stock keys to gain the desired height. You shouldn't crank over about 1.5", since once you go higher than that, you will start to wear out suspension & steering components much quicker. Parts like CVs, tie rod ends, ball joints, and pitman and idler arms will all wear much quicker, and could possibly fail, which would result in loss of vehicle control. Not fun.

 

Yes, you will need an alignment.

 

To crank the torsion bars, first, measure the fender heights. Next, jack the front end of the truck up. Then turn the adjustment bolts clockwise, lower the truck, and re-measure. Then bounce on the front bumper, and drive the truck around the block to allow the suspension to settle. Repeat as needed to acheive the desired lift. Then go get an alignment.

 

Oh, and welcome to the site.

Agreed, be very careful with CV angles.
