torsion bar cranking

how do i crank my torsion bar to get those 1 to 2 inches of lift everyone is talking about? i have an 1998 f150.

On the back of the bars meaning towards rear of vehicle in side the frame running across where the bars connect theres like a fifteen sixteens bolt when u crank it clockwise it pushes up causing it to turn and make it rise. You should use an impact if u can its easier be careful not to go to far itll throw ur tow in off and burn tires. Also a good idea to have allignment shop check after ur done..DAVE
